This position is roughly equivalent to a tenure track Assistant/Associate Professor in US terms. Cambridge University Engineering Department is divided into six divisions which cover all of the main engineering disciplines. This post will be in the Information Engineering division which covers the areas of signal processing, communications and computing as well as control. Undergraduates in engineering now take a four year course leading to the MEng degree. Students take a common course in the first two years and can then specialize in the third and fourth years. The second year control teaching includes one course on Linear Systems and Control together with related courses on Communications, Signal and Data Analysis, and on Dynamics. There are courses in the third and fourth years which cover many areas of control and cater for both generalists and specialists. All of the above are supported by extensive practical classes and design projects. In the fourth year, students also do a major project occupying approximately one half of their time. This may be in collaboration with industry and it is expected that the above lecturer would be fully involved is this aspect of the teaching. The person appointed to the post will be expected to teach in the above areas and to assist in their further development; in particular a significant contribution to the final year projects and experimental work will be expected as well as to the normal lecture courses. The control group currently consists of one Professor and three lecturers, and typically has about two research assistants and 15 PhD students. Active areas of research are in robust control, nonlinear control, identification and computer aided design, with applications in the aerospace, automotive and robotic industries. Candidates should have an established research record in some area of control, or outstanding research potential. In addition to the teaching requirements outlined above, the successful applicant will be expected to pursue research of distinction in control, supervise PhD students and attract funding for their research.

SUMMARY ======= The aim of this book is to present a unified theory of feedback system analysis, design and synthesis that is able to optimize the performance and robustness of control systems. The development of the LQG and H-infinity synthesis theories is split into two parts. In the first, we analyze a finite-horizon version of the problem. The second part tackles the infinite-horizon extension by invoking limiting arguments. Our approach to the synthesis theory is based, therefore, on time-domain techniques which are deeply rooted in the existing and widely known theory of linear quadratic optimal control. We also deal with the approximation of high-order systems by others of lower order. This approximation process is known as model reduction. The inclusion of model reduction is motivated by our belief that control system design cannot be separated from the process of plant modelling. Any serious application of the optimal synthesis methods in this book is bound to involve some model reduction. In addition, the similarity of the mathematical techniques involved in model reduction and H-infinity optimal control makes it appropriate to include this material. Each chapter ends with student exercises; some are straightforward, while others are much more challenging. The easy exercises offer practise in formula manipulation and are designed to help students increase their confidence in the subject. On the whole, they add only minor embellishments to the text. On the other hand, the more difficult exercises expand the text and even develop aspects of the subject we could not touch on in the main body. Answering the more difficult problems requires real work---mastering control theory is not a spectator sport! The exercises are an integral part of the text and there is no doubt that a serious attempt to answer them will greatly improve one's understanding of the subject. A solution to each of the problems is available in a separate solutions manual, a preface to which is also available via anonymous ftp. *.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.** Contributed by: S. Nikitin, nikitin@math.la.asu.edu Title: Global controllability and stabilization of nonlinear systems Author: S. Nikitin This book is based on courses of lectures on nonlinear systems given by author at the Moscow State University (1989 - 1990), at the Moscow Institute of Steel and Alloy (1990 - 1991) and at the Kaiserslautern University (summer 1990, 1991 - 1992). The main purpose of this book is to provide a self-contained, complete and geometrically clear presentation of recent results on global controllability and stabilization. A good deal of effort was put into the development of geometrical control intuition and inspiring the reader to think independently. That is why, the book contains many pictures and exercises. The material presented is organized in such a way that, for Part I, it is only assumed that the reader has mastered the very basic notions of ordinary differential equations theory, general topology and analytic geometry. For Part II the reader is assumed to be familiar with the elements of differential geometry. The present book can serve as a two-semesters course for those students and post-graduates specializing in automatic control theory and mathematical systems theory in applied mathematics departments. ******** You can order this book using the addresses listed below.

Background ---------- The ISE conference will be followed by a set of four workshops focussing on the relationships between methods of control engineering and artificial intelligence in the development of intelligent systems in engineering. The goal of the workshops is to support the exchange of background information and the development of a common understanding of the relative merits and limitations of the various approaches. The initiation of further collaborative actions is expected as a major outcome of the workshops with the long-term goal of bridging the gap between the two classes of approaches. These are intended to be highly interactive sessions leading to a better understanding of the motivation and perspectives of each discipline. The Neuro-Fuzzy Workshop ------------------------ Fuzzy systems and neural nets have been successfully applied to a wide range of application fields including signal processing, control, image analysis, pattern recognition and diagnostics. The combination of both paradigms allows the merging of the sophisticated learning algorithms developed in the realm of neural nets and the representation of qualitative and cognitive transparent rules in fuzzy inference systems. Various architectures for hybrid neuro-fuzzy systems have been proposed: serial and hierarchical coupling of fuzzy systems and neural nets and heterogenous fuzzy-neural nets. This empirical work on neuro-fuzzy combinations has recently been underpinned by theoretical results establishing the direct functional equivalence of certain types of networks and a class of fuzzy systems. The workshop aims to present a balanced overview of this rapidly expanding field both from a theoretical and an application oriented viewpoint. Recent developments in design tools will also play an important role. Specific topics for the workshop include, but are not limited to, - Functional equivalence of neural and fuzzy systems - Structure selection - Common training algorithms - Transparency/interpretation of trained systems - Knowledge-based neural networks - Fuzzy-neural adaptive control - Computational issues and implementation - Description of industrial applications - Design tools for hybrid architectures Papers will be selected according to their quality, significance, originality and their potential to generate discussions on the major theme of the workshop. Presentations should be specifically designed to support an exchange of ideas and to indicate areas where contributions from the respective other discipline are to be expected. Informal working notes will be distributed during the workshop; no copyright will be requested. A paper must not exceed 10000 words, excluding references and abstract. People who wish to attend the workshop without submitting a paper should a send a letter describing their background and research interests by the paper submission deadline.
