Recipient of Richard E. Bellman Control Heritage Award

Citation:
For pioneering contribution to control theory and engineering, and for inspirational leadership as mentor, advisor, and lecturer over a period spanning four decades

Biography:

Petar V. Kokotović received graduate degrees in 1962 from the University of Belgrade, Yugoslavia, and in 1965 at the Institute of Automation and Remote Control, USSR Academy of Sciences, Moscow. During his studies, he worked for two six month periods in 1956, at Electricite de France, Paris and then in 1957, at AEG, Stuttgart, Germany. From 1959 until 1966, he was with the Pupin Reseach Institute in Belgrade, Yugoslvia. From 1966 until 1990 he was with the Department of Electrical and Computer Engineering and the Coordinated Sciences Laboratory at the University of Illinois, Urbana, where he held the endowed Grainger Chair. In 1991 he joined the Electrical and Computer Engineering Department of the University of California at Santa Barbara, where he is currently the Director of the Center for Control Engineering and Computation.

In the 1960’s, Kokotović developed the sensitivity points method, a precursor to adaptive control, still in use for automatic tuning of industrial controllers. In the 1970’s, he pioneered singular perturbation techniques for multi-time-scale design of control systems and flight trajectories, which found widespread applications. One of them was a coherency aggregation methodology for large scale Markov chains and power systems. In the 1980’s, Kokotović and coworkers identified the main forms of adaptive systems instability and introduced redesigns that made adaptive controllers more robust. Kokotović’s current research is in nonlinear control, both robust and adaptive. He initiated the development of a popular nonlinear recursive design-backstepping, and its use for robust and adaptive nonlinear control. As a long-term industrial consultant, Kokotovic contributed to the design of computer controls for car engines and automotive systems at Ford, and to power system stability analysis at General Electric. Recently, he led a five-year collaborative research (with United Technologies) on nonlinear control of axial compressors for jet engines.

Professor Kokotović supervised some 30 Ph.D. students and 20 postdoctoral researchers. With them he co-authored numerous papers and ten books, four of which appeared in 1995-96. Professor Kokotović is a fellow of the IEEE and a member of the U.S. National Academy of Engineering. He is the recipient of the two highest control engineering awards: 1990 Quazza Medal by the International Federation of Automatic Control, and the 1995 Control Systems Field Award by the IEEE. He also received an Eminent Faculty Award, two Outstanding IEEE Transactions Paper Awards (1983 and 1993), and delivered the 1991 IEEE Control Systems Society Bode Prize Lecture. His most recent recognition is the 2002 IEEE James H. Mulligan Jr. Education Medal.

1997: Rudolf E. Kalman
Recipient of Richard E. Bellman Control Heritage Award

Citation:
For fundamental contributions to control and system theory

Biography:

R.E. Kalman was born in Budapest, Hungary, on May 19, 1930. He received the bachelor's degree (S.B.) and the masterís degree (S.M.) in electrical engineering, from the Massachusetts Institute of Technology in 1953 and 1954, respectively. He received the doctorate degree (D.Sci.) from Columbia University in 1957. His major positions include that of Research Mathematician at the Research Institute for Advanced Study in Baltimore, 1958-1964; Professor at Stanford University 1964-1971; Graduate Research Professor at the Center for Mathematical System Theory, University of Florida, Gainesville 1971-1993. Moreover, since 1973 he has also held the chair for Mathematical System Theory at the ETH (Swiss Federal Institute of Technology) Zurich.

He is the recipient of numerous awards, including the IEEE Medal of Honor (1974), the IEEE Centennial Medal (1984), the Kyoto Prize in High Technology from the Inamori foundation, Japan (1985), the Steele Prize of the American Mathematical Society (1987). He is a member of the U.S. National Academy of Science, the U.S. National Academy of Engineering, a foreign member of the Hungarian and French Academies of Science, and has received a number of honorary doctorates. Kalman's first major contribution was the introduction of the self-tuning regulator in adaptive control. Between 1959 and 1964 Kalman wrote a series of seminal papers. First, the new approach to the filtering problem, known today as Kalman Filtering was put forward. In the meantime, the all pervasive concept of controllability and its dual, the concept of observability, were formulated. By combining the filtering and the control ideas, the first systematic theory for control synthesis, known today as the Linear-Quadratic-Gaussian or LQG theory, resulted. The next contribution was the solution of the black box modelling problem in the linear case, known as realization theory. This problem involves the construction of the state from input/output measurements. The next milestone in the sequence of contributions was the introduction of module theory to the study of linear systems.

Over the past 15 years Kalman has devoted his efforts to the understanding of the problem of identification from noisy data with particular attention to the connections with econometrics, statistics and probability theory.

1996: E.G. Gilbert
Recipient of Richard E. Bellman Control Heritage Award

Citation:
In recognition of a distinguished career in automatic control, with pioneering research contributions to a broad range of subjects including linear multivariable systems theory, computation of optimal controls, nonlinear systems theory, and motion planning in the presence of obstacles

Biography:

Elmer G. Gilbert received his B.S.E. and M.S.E. degrees in Electrical Engineering in 1952 and 1953, respectively, and his Ph.D. in Instrumentation Engineering in 1957, all from the University of Michigan. He has been with the University of Michigan's Department of Aerospace Engineering (then called Aeronautical Engineering) since 1954, becoming Professor in 1963 and Professor Emeritus in 1994. Visiting positions include the United States Air Force Academy (1965), the Johns Hopkins University (1974-1976, 1991-1992), the University of Minnesota (1985-1986), and the National University of Singapore (multiple times 1997-2005).

Dr. Gilbert has had a highly varied career in engineering development, basic research, and teaching. This has led to over 100 publications and 9 patents. In the systems and control area at the University of Michigan, he was active in curriculum development and as an advocate for cross-department cooperation. He was Chair or Co-Chair of doctoral committees for 23 students.

During his graduate studies, he was involved in the department’s analog computer and aircraft simulation research programs. This activity continued through the 1960’s, both in the department and as a consultant to Applied Dynamics Incorporated, a computer firm founded in 1957 by him and two other department professors, Robert M. Howe and Edward O. Gilbert. Up to 1970, he was a key member of the Applied Dynamics group responsible for conception and development of new products, primarily state-of-the-art analog and hybrid computers. The firm still exists, specializing in hardware and software tools for hardware-in-the-loop simulation, system prototyping, and embedded controller software.

The 1960’s were a period of rapid development for the theory and application of control systems. This was the area of work in which Dr. Gilbert’s university activities were centered. A principal interest was the design of multivariable control systems. Based on his experience in system simulation, he observed that casual use of matrices of transfer functions did not allow adequate descriptions of the underlying dynamics they represent. This led to his widely recognized work (1962-1963) on the role of observability and controllably on state-space system representations, including the Gilbert realization, now a standard topic in system textbooks. A long-standing problem in multivariable linear-systems theory, not involving transfer functions, was input-output decoupling by state feedback. Dr. Gilbert gave its first complete solution in 1969. The result led to a large body of subsequent research in the field. Computational issues motivated much of his other research in the 1960’s. This included convexity-based, abstract optimization algorithms that led to the efficient solution of practical optimal control problems (for example, minimum-fuel impulsive control).

Dr. Gilbert’s research contributions, after the 1960’s, are characterized by overlapping themes that already had appeared in his prior work: dynamic system representation and realization, optimal control, systems with hard (point-wise in time) constraints, and effective computational procedures. Specific topics treated include: periodic optimal control and its application to improved aircraft flight efficiency, feedback decoupling for nonlinear systems, power-law functional expansions for the input-output response of nonlinear systems, stability of nonlinear control systems with feedback provided by model predictive control, efficient procedures for computing the distance between objects (polytopes) in 3 space, path planning for robots in the presence obstacles, domains of attraction for linear systems with hard constraints and set bounded disturbances, and reference and command governors for linear systems with disturbances and hard constraints. Some of the papers on these topics published by Dr. Gilbert and his colleagues have become standard references in the control systems literature. Perhaps the most widely recognized paper is the one in 1988 with S. S. Keerthi on model predictive control. It was the first contribution to address in specific, rigorous ways stability issues crucial in many current control applications.

Recognitions for Dr. Gilbert’s contributions include: Fellow of the Institute for Electrical and Electronics Engineering for “Contributions to multivariable and optimal control systems” (1979), election to the Johns Hopkins University Society of Scholars (1990), a Distinguished Faculty Achievement Award from the University of Michigan (1991), Fellow of American Association for the Advancement of Science for “Contributions to theory and practice of multivariable, optimal, nonlinear, and computer control systems and to control engineering education" (1995). In 1994, he was elected to the National Academy of Engineering: "For contributions to the theory and practice of multivariable, optimal, non-linear, and computer control systems, and to control engineering education." In 1994, he received the IEEE Technical Field Award in Control Systems "For pioneering and innovative contributions to linear state space theory and its applications, especially realization and decoupling, as well as to control algorithms." In 1996, he received the Richard E. Bellman Control Heritage Award from the American Automatic Control Council "In recognition of a distinguished career in automatic control, with pioneering research contributions to a broad range of subjects including linear multivariable systems theory, computation of optimal controls, nonlinear systems theory, and motion planning in the presence of obstacles."

Text of Acceptance Speech:

July 4, 1996

I am immensely pleased by the Award! It is indeed a special honor, coming from the American Automatic Control Council, which has done so much to advance and to unify the field of control. I recall with delight the long sequence of Joint Automatic Control Conferences and the subsequent American Control Conferences. The Council's many current activities, including its participation in this 13th IFAC World Congress, continue its invaluable service to the control community.

In receiving the award I wish to recognize the support of friends, colleagues and former students. They have played a vital role in my work. I must also acknowledge the special influence of others I have known mostly or entirely through their publications. It is no surprise that Richard Bellman was one of them. Let me make a few remarks about his legacy and how it affects us today.

In examining his writings I am struck by his genuine interest in applications and obvious desire to make his findings useful to a wide audience. In this, I believe, there are lessons to be learned. I'll note four.

1. Fundamental ideas have greater power when they are elegantly expressed. There is no better example than Bellman's formulation of dynamic programming. Its wonderfully stated ideas permeate and illuminate much of what we do, ranging from deep theoretical results in optimal control to practical, on-line implementation of controllers.

2. Propagation of knowledge is enhanced by the establishment of connections across fields and disciplines. Bellman's 1960 book, "Introduction to Matrix Analysis," illustrates this point beautifully. The discussions and bibliographies and the end of each chapter are marvelous sources of insight and diversity.

3. In mathematical exposition, clarity and accessibility are precious attributes. Bellman had a special talent for keeping mathematical developments closely connected to first principles and organizing them in simple, easy to understand parcels. He had the courage to compromise generality for clarity and, on occasion, rigor for insight.

4. Numerical issues are crucial to control applications. Bellman realized this early, four decades ago, when he addressed controller implementation, algorithm design, error analysis, and computational complexity.

Over the years the field of control has become mature, complex and diverse. We now need, as Richard Bellman did so well, to give greater attention to the means by which we encourage its progress and impact on society. On that point I will end. Thank you.
