Scherer (scherer@tudw03.tudelft.nl) Delft University of Technology & Philips Research Laboratories Four Year Ph.D. Position in Robust Control In a joint project of the TU Delft (Delft) and Philips Research (Eindhoven) the goal is to develop methodologies for system identification and robust control which are specially suited for high-performance motion tracking control of consumer electronic products. Particular attention should be paid to the integration of model identification with an assessment of the underlying uncertainties and the design of controllers which provide desirable performance for all models in the identified class. These aims should be achieved in close cooperation of two investigators, one responsible for identification aspects (Hans Doetsch, supervised by Dr. P.M.J. van den Hof) and one concentrating on robust controller design (vacant position, supervised by Dr. C.W. Scherer). The candidate is expected to contribute in the modeling of the occurring uncertainties, the formulation of robust control problems guaranteeing stability and performance, the assessment of applicability or the development of variations of existing synthesis techniques (H-infinity, mu-synthesis, LMI-techniques, multiobjective control), and the controller implemention on a prototype CD player mechanism. In view of this broad range of topcis we expect any applicant to have, in addition to a firm engineering background, an above average knowledge of the mathematics related to robust control. The research should start in fall 1994 and is performed in the Systems and Control Group at the TU Delft, headed by Prof. O.H. Bosgra, with regular meetings with the group around Dr. M. Steinbuch at Philips Research Eindhoven. Please send your application including a curriculum vitae and a description of undergraduate and graduate studies with details of the final year project (including marks/grades) to Dr. Carsten Scherer Mechanical Engineering Systems and Control Group Delft University of Technology Mekelweg 2 2628 CD Delft The Netherlands Phone: +31-15-785899 E-mail: scherer@tudw03.tudelft.nl The candidate should make sure that least two letters of recommendation are sent to the above address. *.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.** Contributed by Colin Bravington, Manager, Advanced Control Club.

Knobloch, Universitaet Wuerzburg, Germany / A. Isidori, Universita degli Studi di Roma, Italy / D. Flockerzi, Universitaet Wuerzburg, Germany About the Book: One of the key concerns in modern control theory is the design of steering strategies. The implementation of such strategies is done by a regulator. Presented here is a self-contained introduction to the mathematical background of this type of regulator design. The topics selected address the matter of greatest interest to the control community at present, namely, when the design objective is the reduction of the influence of exogeneous disturbances upon the output of the system. In a first scenario the disturbance signal is regarded as a deterministic time series with known dynamics but unknown parameters. The design objective is then the asymptotic disturbance compensation. In a second scenario, no information about the disturbance signal is available apart from some bounds. Here, in an H-approach, control strategies are worked out which will prove efficient for all such disturbances. The intention of this book is to present ideas and methods on such a level that the beginning graduate student will be able to follow current research. New results are included, especially for nonlinear control systems, and as a service to the reader, an extensive appendix presents topics from linear algebra, invariant manifolds and calculus of variations, information which is hardly to be found in standard textbooks.

Berenstein, University of Maryland, College Park, USA / R. Gay, Universite de Bordeaux, France / A. Vidras, A., Kyoto University, Japan / A. Yger, Universite de Bordeaux, France About the Book: The objective of this monograph is to present a coherent picture of the almost mysterious role that analytic methods and, in particular, multidimensional residue have recently played in obtaining effective estimates for problems in commutative algebra. Bezout identities, i. e., f1g1 + ... + fmgm = 1, appear naturally in many problems, for example in commutative algebra in the Nullstellensatz, and in signal processing in the deconvolution problem. One way to solve them is by using explicit interpolation formulas in Cn, and these depend on the theory of multidimensional residues. The authors present this theory in detail, in a form developed by them, and illustrate its applications to the effective Nullstellensatz and to the Fundamental Principle for convolution equations. The objective of this monograph is to present a coherent picture of the almost mysterious role that analytic methods and, in particular, multidimensional residue have recently played in obtaining effective estimates for problems in commutative algebra.

Bulirsch, TH Muenchen, Germany / D. Kraft, Fachhochschule Muenchen, Muenchen, Germany About the Book: There is public agreement that all resources should be used sparingly both from the point of view of economy and ecology. Therefore optimization is the tool of choice in controlling industrial and economic processes. This book collects the reviewed papers of the ninth IFAC Workshop on Control Applications of Optimization, which took place in Munich in September 1992. Highlights from the ensuing discussions have been incorporated by the authors. The volume reflects the state of the art in the application of finite and infinite dimensional optimization to open and closed loop control problems. Its spectrum ranges from theoretical foundations of the proposed methods and numerical implementations of algorithms to applications to real world problems. Emphasis lies on the solution of practical industrial problems in aerospace, mechanical and electrical engineering, manufacturing technology and economic and management systems. Among the theoretical papers are contributions from nonlinear programming (interior point methods, large structured problems, nonsmooth problems, and vector-valued criteria) and optimal control (multipoint boundary value problems, state and control constraints, feedback solutions, differential-algebraic systems and differential games).

Aburdene : Call For Papers Journal of the Franklin Institute Engineering and Applied Mathematics As the new editors of the journal, we are writing to tell you something of our plans and invite your collaboration in continuing the development of this historic journal, now in its 169th year. It is our intention that the journal will continue as a journal of engineering systems and the mathematics that underlies them. Its present focus is upon electrical and mechanical engineering, especially information and communication systems, including control theory; robotics; wavelets; nonlinear dynamics and fractals; neural computation; signal processing and mechanics. We realize that no description of this kinds can be comprehensive and we therefore encourage authors to put forward new topics for publication, provided that they fall within the broad scope of the journal or are related to one of the current topics. Of particular interest are emerging mathematical techniques, and especially their applications. The core of the journal will remain research papers. To encourage definitive accounts of research we emphasize that there is no arbitrary limit on the length of papers. Authors of particularly long papers, more than 6,000 words, should consult with us beforehand; but the bibliographic data for the journal shows that its papers are cited for many years and this is a trend we wish to continue. Papers are normally published within eight months of receipt and often more quickly if major revisions are not required. In addition, we are introducing a section of brief communications which will be published in 3-4 months provided they warrant the urgency. We intend to publish review articles and we invite authors to put forward proposals for such articles, to be major pieces of writing up to 10,000 words long. Review articles may either cover a relatively narrow topic at the frontiers of research or may be broader with a strong tutorial flavor. Manuscripts for publication should be sent directly to the managing editor at the Franklin Institute.

We invite you and your colleagues to submit a proposal by July 15, 1994. THE PROPOSALS SHOULD BE SENT TO THE SIAM OFFICE. The final decision on the mini-symposia will be made by the the ICIAM Program Committee to insure a balanced program. Forms for making the proposal can be obtained from SIAM (iciam@siam.org) or from the SIAM gopher. (These forms are for the genaral call for mini-symposia; ignore the dates and address of return.) We welcome suggestions for other topics and organizers. A final decision on mini-symposia will be made by Sept 15, 1994. Here is some information and helpful comments. These suggestions are guides but they are not inviolate. 1) In the interest of fairness, an individual should not participate and/or organize more than one mini-symposium. 2) The organizer should be a member of SIAM but it is desirable that the speakers be chosen to reflect the international character of the ICIAM meeting. 3) If the organizer is a speaker then he/she should nominate another person to chair the session. 4) No funding has been provided for the expenses of these mini-symposia. 5) The mini-symposium format allows for a variety of formats eg. roundtable discussions, presentations of variable length, etc. There will be a more general call for submission of mini-symposium at a later date.
