Congratulations, Tony! ****** AWARDS AND RECOGNITION ****** [Contributed by Rob Stengel (stengel@pucc.bitnet)] 1991 Awards of the American Automatic Control Council The Richard E. Bellman Control Heritage Award is given for distinguished career contributions to the theory or applications of automatic control. The award is the highest recognition of professional achievement for U.S. control systems engineers and scientists. It was awarded to John G. Truxal, Professor and former Dean of Engineering and Applied Sciences at the Stony Brook campus of the State University of New York, in recognition of life-long contributions to the field of automatic control as an author, teacher, and academic administrator, and for his continuing efforts to foster understanding of the role of technology in the conduct of human affairs. The Donald P. Eckman Award is given for outstanding accomplishments by a young engineer in the field of automatic control. It was established in memory of Donald P. Eckman, who made important contributions to control theory and practice in the 1950s and 1960s but who died tragically in an automobile accident in 1962. It was awarded to Carl Nett, Associate Professor of Aerospace Engineering at the Georgia Institute of Technology, for his exceptional contributions to control design methodology as a young engineer in industry and academia. The Education Award is given for outstanding contributions to education in the field of automatic control. It was awarded to Michael Rabins, Professor of Mechanical Engineering at Texas A&M University, for outstanding and lasting contributions to the field of automatic controls and dynamic systems through innovative and exemplary leadership in controls education. The O. Hugo Schuck Best Paper Award is given for the best paper presented at the previous year's American Control Conference. The award is named for O. Hugo Schuck, a pioneer in the practice of flight control design at Honeywell, Inc., and later at NASA. This year, the award is shared by Gary Yamaguchi, Assistant Professor of Biomedical Engineering at Arizona State University, and Felix Zajac, Professor of Mechanical Engineering at Stanford University and Director of the Palo Alto Veterans Affairs Rehabilitation R&D Center. Their paper, "Modeling FES Actuation and Control of Multisegment Limb Movements," was judged the best among the several hundred papers presented at the 1990 ACC. ******* CHANGES OF ADDRESS, PHONE, ETC ******* Washington University, St. Louis telephone numbers have been changed as of August 5, 1991.

Among different time-domain approaches to this class of worst-case design problems, the one that uses the framework of dynamic (differential) game theory stands out as the most natural. This is so because the original H-infinity optimal control problem (in its equivalent time-domain formulation) is in fact a minimax optimization problem, and hence a zero-sum game, where the controller can be viewed as the minimizing player and the disturbance as the maximizing player. Using this framework, the authors develop in this book a complete theory that encompasses continuous-time as well as discrete-time systems, finite as well as infinite horizons, and several different measurement schemes, including closed-loop perfect state, delayed perfect state, sampled state, closed-loop imperfect state, delayed imperfect state and sampled imperfect state information patterns. The authors believe that the theory is now at a stage where it can easily be incorporated into a second-level graduate course in a control curriculum, that would follow a basic course in linear control theory covering LQ and LQG designs. The framework adopted in this book indeed makes such an ambitious plan possible. For the most part, the only prerequisite is a basic knowledge of linear control theory. No background in differential games, or game theory in general, is required, as the requisite concepts and results have been developed in the book at the appropriate level. Furthermore, the book is written in such a way that makes it possible to follow the theory for the continuous- and discrete-time systems independently (and also in parallel). The general framework adopted, and the methodologies developed, also open new avenues of research for the reader, to extend these results to more general classes of systems, such as nonlinear plants and/or distributed parameter systems.

COMPUTATIONAL ASPECTS AND ANALYSIS By: Sabine Van Huffel and Joos Vandewalle Frontiers in Applied Mathematics 9 "...TLS (Total Least Squares) represents a technique which synthesizes statistical and numerical methodologies for solving problems arising in many applications areas. The authors of this monograph have been leaders in showing how to use TLS for solving a variety of problems, especially those arising in a signal processing context. They give an elegant presentation of the various aspects of the TLS problem. Their survey encompasses the many elements required to understand the problem. It is a pleasure to read such a clear account which is presented using standard mathematical ideas and nomenclature." - Gene H. Golub, Department of Computer Science, Stanford University This is the first book published to be devoted entirely to total least squares. The authors give a unified presentation of the TLS problem-- a description of its basic principle, the various algebraic, statistical, and sensitivity properties of the problem are discussed, and generalizations are presented. Applications are surveyed to facilitate uses in an even wider range of applications. Whenever possible, comparison is made with the well-known least squares methods.

In many cases this dominance extends into the system controls. In general, the more complex the control system, the more it costs, the harder it is to maintain, and the less reliable it is. For these reasons, control system complexity is an important issue which should be directly addressed during control system design efforts. The complexity of a control system is largely determined by the underlying control configuration. The control system configuration is arrived at through a design process which considers the organizational aspects of the control system. These organizational aspects include the selection and partitioning of the measurements and manipulations to be used for closed--loop control. These two tasks constitute particularly important aspects of control configuration design, as the complexity of the resulting control system is primarily determined by i) the number of measurements and manipulations selected for closed--loop control, and ii) the number of distinct feedback paths employed from the measurements to the manipulations. Recently, progress has been reported on the control configuration design problem in a series of papers by Reeves, Nett, and Arkun. Though the progress represents only a modest beginning, the authors hope that their work will spur others to undertake research on this most important problem. As such, the authors have decided to make their work in this area widely available to others via e-mail. The specific items available by e-mail include: 1) A postscript file of the paper ``Control Configuration Design for Complex Systems: A Practical Theory,'' by Reeves, Nett, and Arkun. 2) A postscript file of the paper ``Control Configuration Design for a Mixed Vectored Thrust ASTOVL Aircraft in Hover'', by Hoskin, Nett, and Reeves. 3) A postcript file of the manual for a MATLAB Toolbox for Control Configuration Design authored by Reeves, Nett, and Arkun. 4) The complete set of m-files for the MATLAB toolbox described above.

As a consequence of the present difficult economic situation of Philips, Philips Research Laboratory Belgium (PRLB) closed down on June 30, 1991 and all its members will be laid off. PRLB was created in 1963. Its mission had been to provide research support in applied mathematics and computer science. It is a fact that PRLB had gained in the course of years an international reputation for the excellence of its research work in various fields and especially in applied mathematics. Notable in that respect were research contributions in circuit theory, coding theory and combinatorics, signal processing, neural nets, numerical linear algebra, telecommunications and cryptography. The fate of PRLB means the disappearance of one of the very few European industrial research centers in applied mathematics. PRLB members who were working in applied mathematics include: Xavier Aubert, Chris Blondia, Pierre-Jacques Courtois, Marc Davio, Philippe Delsarte, Claude Dierieck, Yves Genin, Yves Kamp, Vinciane Lacroix, Benoit Macq, Philippe Piret, Jean-Jacques Quisquater, Christian Ronse, Guy Scheys, Pierre Semal, Dirk Slock, Andre Thayse, Vincent Van Dongen, Paul Van Dooren *.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.** End of E-LETTER 43
