Summer Professional Program 16.30s Tuition: $1,500 CEUs: 3.0 Robustness is the most essential quality of a properly designed control system. Thus, it is not surprising that so much research effort has been spent over the past five decades into examining ways to analyze robust stability and performance of uncertain control systems. Initiated during World War II in Russia, this research has culminated in the past decade with the derivation of closed-form solutions to the so-called Hinfinity problem and the advent of powerful computational tools to handle robustness problems. Today, the large number of results available in robust control theory makes it hard for the user to choose among many possible methodologies the one which is going to fit his/her needs best. The main goal of this course is to help the user understand a very large number of robust control methodologies in a unified way. Effort will be spent at giving an objective comparison of various stability and performance criteria. In particular, the artificial separation between frequency-domain and time-domain approaches to robustness analysis will be eliminated, and seemingly different notions such as quadratic stability, Popov's criterion, mu-analysis will be seen as particular instances of a single concept involving Linear Matrix Inequalitiess (LMIs). Objective comparison of various stability criteria will be performed, through a study between the different possible trade-off between accuracy and required computational load. We will investigate those methods which have had the most spectacular practical applications in spacecraft control engineering. We will present an overview of the currently existing software tools for robust control system analysis and synthesis, and we will spend time studying the recently developed interior-point algorithms for solving convex programs. Control engineers working in Aerospace, Electrical and Process Engineering as well as many other relevant fields will find this course a precious complement to classical, multivariable linear control theory. Numerous practical examples based on the instructors' experience will illustrate the practical value of the matreial presented in this course.

Camacho and Carlos Bordons PUBLISHER: Springer-Verlag ISBN: 3-540-19924-1 Model Predictive Control has developed considerably in the last few years, within both the research control community and industry. The reason for this success can be attributed to the fact that Model Predictive Control is perhaps the most general way of posing the process control problem in the time domain. Model Predictive Control formulation integrates optimal control, stochastic control, control of processes with dead time, multivariable control and future references when available. Another advantage of Model Predictive Control is that because of the finite control horizon used, constraints, and in general non-linear processes, which are frequently found in industry, can be handled. MODEL PREDICTIVE CONTROL IN THE PROCESS INDUSTRY seeks to fill the gap between the empirical way in which practitioners tend to use control algorithms and the powerful but sometimes abstractly formulated techniques developed by the control researchers. The book focuses on implementation issues for Model Predictive Controllers and intends to present easy ways of implementing them in industry. The book also aims to serve as a guideline of how to implement Model Predictive Control and as a motivation for doing so by showing that using such a powerful control technique does not require complex control algorithms.

It is intended that both research students and practicing engineers in general areas of control system theory use the book as a textbook or as a reference book. In preparing this book some basic background in linear systems and linear optimal control theory as well as intermediate-level mathematics is assumed. On the overall objectives of this book: It is intended to provide a broad scope of sensitivity theory as developed in the last several decades pertaining to electrical engineering. In this regard, preserving the past is one of the main features of this project. The given list of classified references, and Appendix B which in effect is a sensitivity tree, shows where most topics are, and this feature is particularly useful for new researchers who may not have followed the overall development of this theory and may need a broad view of these issues before they launch their research activities in this area. Indeed this service provides an opportunity for new researchers to review thoroughly the earlier work. It is also hoped that a clear and coherent research media in this very broad area is introduced. On the technical aspects of the book: It is intended to provide a trajectory which covers most essential features of sensitivity theory as described in the book. It is the opinion of this author that sensitivity in its most generic sense is synonymous with the notion of distance. For instance, the "distance" between the desired behavior and an actual situation represents sensitivity. The more sophisticated and the more abstract the desired and actual situations become, the more sophisticated and the more abstract mathematics are needed to measure and/or to compensate this distance. The book is prepared with the intention to direct the readers towards the advanced aspects of this theory.

Vaccaro, Department of Electrical Engineering, University of Rhode Island, U.S.A. From the Preface: This book is intended as the text for a senior-level course on the analysis and design of digital control systems. It is assumed that the reader has had a first course in control theory. This book shows how linear algebra and state-space system theory are used to design digital control systems. In addition, classical frequency-domain tools such as Bode and Nyquist plots are used to analyze digital control systems designed by state-space techniques. A collection of MATLAB functions called the STATE-SPACE DIGITAL CONTROL TOOLBOX is available. The functions implement all of the design and analysis tools covered in this book, and programs are included to simulate continuous-time systems under digital control. The Toolbox is available from The MathWorks anonymous ftp server at ftp.mathworks.com in pub/books/vaccaro/. The Toolbox comes with two demonstration scripts that illustrate most of the toolbox functions. The scripts show the design, analysis, and simulation for (1) control of an inverted pendulum on a cart, and (2) multivariable digital flight control of an aircraft. OUTLINE OF THE BOOK Chapter 1 provides an introduction and motivation for the book. Chapter 2 presents the linear algebra and matrix theory needed for the rest of the book. Chapter 3 describes state-space and transfer function models for continuous-time and discrete-time systems. In addition, state-space and transfer function models for several example systems are derived. Chapter 4 shows that when a linear, continuous-time plant is operating under digital control, it is possible to replace the continuous-time model of the plant by a discrete-time model that describes the behavior of the plant exactly at sampling instants. This chapter also shows how to obtain exact discrete-time models for plants with time delay at the input. Chapter 5 presents tools for frequency-domain analysis -- Bode plots and Nyquist plots for discrete-time systems -- and discusses stability and gain/phase margins. These tools are used to assess the robustness of control systems designed in later chapters. The topic of steady-state error and system type is also covered. Chapter 6 shows how to design regulators using digital state feedback. Normalized Bessel polynomials are introduced as a simple way to choose closed-loop pole locations to achieve a desired speed of response for the closed-loop system. The robustness of the system is assessed by looking at a Nyquist plot of the loop transfer function. The relationship between state feedback and PID control is presented. Chapter 7 considers the design of observers to estimate the value of the state vector of the plant from measurements of its input and output. Both full and reduced-order observers are presented. We show how to design observers that recover much if not all of the stability margins of the state- feedback regulator. Chapter 8 shows how to introduce a reference input into a regulator structure to obtain a tracking system. A complete algorithm to design tracking systems that are robust with respect to persistent disturbances and model inaccuracies is given. The tracking systems in this chapter are designed using full state feedback as well as observers. Chapter 9 considers multivariable regulation and tracking systems. This chapter presents an algorithm that finds the matrix of feedback gains that optimizes a robustness criterion. This chapter also includes the multivariable version of the tracking algorithm from Chapter 8. Chapter 10 is an introduction to optimal control. The linear quadratic regulator for multivariable systems is derived. Only the steady-state (infinite horizon) case is considered, and so the solution to the optimal regulation problem is constant state feedback.

One class of techniques is to specify a performance function and then optimize it, and one such performance function is the norm of the closed-loop transfer matrix, suitably weighted. The two most popular norms to optimize are the H2 and H-infinity norms. The fact that most new industrial controllers are digital provides strong motivation for adapting or extending these design techniques to digital control systems. This book is intended as a graduate text in linear sampled-data (SD) control systems. The subject of SD control is a subdomain of digital control; it deals with sampled signals and their discrete-time processing, but not with quantization effects nor with issues of real-time software. SD control systems consist of continuous-time plants to be controlled, discrete-time controllers controlling them, and ideal continuous-to-discrete and discrete-to-continuous transformers. As a prerequisite, the ideal reader would know multivariable analog control design, especially H2 and H-infinity theory---a user's guide to H2 and H-infinity theory is presented in Chapter 2.

Lewis CALL FOR PAPERS Neural Networks and Fuzzy Systems for Closed-Loop Control Applications A Special Issue of: "Journal of Intelligent Control and Systems" Special Issue Editors: F.L. Lewis and K. Liu Automation and Robotics Research Institute The University of Texas at Arlington 7300 Jack Newell Blvd. S Ft. Worth, Texas 76118-7115 Papers are solicited for a special issue on Neural Networks and Fuzzy Systems for Closed-Loop Control Applications of the "Journal of Intelligent Control and Systems". Both short papers and regular papers are desired. The format of JICS is identical to that of IEEE Transactions. Intelligent controllers have the potential to significantly improve the performance of complex nonlinear processes. Neural networks and fuzzy systems have been applied with considerable success in digital signal processing, decision-making, classification, and other open-loop applications. However, closed-loop control applications of neural networks and fuzzy systems have generally been ad hoc, with no repeatable design algorithms or proofs of guaranteed stability. In spite of the lack of rigorous techniques for intelligent control system design, neural network and fuzzy system controllers have enjoyed remarkable success in complex control applications. This motivates one to use mathematical approaches to provide understanding and to shed light on further possibilities. It is the proofs that yield valuable information concerning: (1) the structure of the neural or fuzzy control system, (2) modified learning rules that keep tracking errors small and adaptive parameters bounded, and (3) additional control input terms that ensure robustness against unforseen disturbances. Without guaranteed performance, acceptance of intelligent controllers by the control systems community and US industry will not be forthcoming. Therefore, this special issue will focus on closed-loop control applications of neural networks and fuzzy systems that offer repeatable design algorithms and mathematical proofs of stability and performance. Papers that present simulations following nonrigorous discussions cannot be included. The objective of this special issue is to provide a forum for developing paradigms for intelligent control systems in the sense of T.S. Kuhn's "Structure of Scientific Revolutions". The Special Issue will appear in early 1996. Four copies of manuscripts should be submitted for review by 15 July 1995: Neural net papers should be addressed to F.L.

Delp; Purdue University The Image and Multidimensional Signal Processing Technical Committee of the IEEE Signal Processing Society has established a tradition of biennial workshops that have been intellectually stimulating and held in interesting places. The Ninth Workshop, to be held in cooperation with the Society for Imaging Science and Technology continues this tradition. It will be held in Belize which is located on the Caribbean Sea directly south of the Yucatan Peninsula and east of Guatemala, just two hours by plane from Miami. Belize has a subtropical climate. The workshop will take place in the dry season when temperatures will average 22C. There are beautiful Mayan ruins in Belize and the longest barrier reef in the Western Hemisphere. The workshop will be held in Belize City at the Radisson Hotel. The theme of the workshop is ``Model-Based Methods in Imaging: This was partly motivated by the NSF-sponsored workshop on Future Directions in Signal Processing that was held in Keystone, Colorado in November 1991. At this workshop,the task group in the IMDSP area identified a need for more emphasis on model-based methods, including models for signal content and models for the human viewer. In addition, it was felt that there was a need for more work on image quality metrics. It is the intention of this workshop to address these topics: Physics-based models Multiresolution models Models for the human visual system Color models Image and video quality metrics Image and video compression Image and video analysis Image rendering for printing and display Color imaging Radar imaging Medical imaging Participation in the workshop will be both by invitation and application. Prospective attendees will submit a 2-page summary in final form. If the paper is accepted the summary will appear in the workshop digest as submitted. Authors should obtain the author's kit via anonymous ftp to skynet.ecn.purdue.edu (128.46.154.48) in the directory /pub/dist/imdsp96.

Statistical Process Control techniques were developed by statisticians for use in the parts industry while Automatic Process Control techniques were developed by engineers for use in process industries. The sharp lines dividing these industries have recently begun to dissolve bringing control engineers and statisticians into closer contact with each other. This conference aims to provide control engineers and statisticians with an opportunity to exchange ideas about integrating the two approaches to Process Control. The conference ( originally suggested by the Quality Improvement committee of the Business and Industry section of the Royal Statistical Society ) is being organised jointly by the University of Hertfordshire Business School, the City University School of Mathematics, Actuarial Science and Statistics, and the University of Newcastle Department of Engineering Mathematics. There will be four half day sessions entitled: Overview; Process modelling; Process control; Forward with new thinking. Each session will be introduced with a keynote talk and will be followed by a number of shorter invited and contributed case studies. Peter Caines (McGill University) and Julian Morris (Newcastle University) have agreed to introduce the Overview and Forward with new thinking sessions. The title of Professor Morris' talk is "Modelling human intelligence to solve engineering problems". Invited speakers include: Tom Fearn (University College London) on "A case study on experimentation in the food industry", Luc Pronzato (University of Nice), Ron Leigh (University of Westminster) on "Adaptive control of multivariate batch processes using digital models" , Ming Tham (Newcastle University) on "A practical application of adaptive control", and Mike Grimble (University of Strathclyde) "Advanced control and simulation techniques for the manufacturing and process industries" Titles and abstracts for contributed papers should be sent, as soon as possible, to: The Control of Industrial Processes Conference Secretary The Business School Development Unit Second Floor Business Link 45 Grosvenor Road St Albans Hertfordshire AL1 3AW ( phone: +44 (0)1727 813611 ) ( fax: +44 (0)1707 284649 ) *.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.** Contributed by: Renny E.
