Short Biography and Research Interests
P. S. Krishnaprasad received his Ph.D. degree from Harvard University in 1977.
He was on the faculty of the Systems Engineering Department at Case Western
Reserve University from 1977 to 1980. He has been with the University of Maryland
since August 1980, where he has held the position of Professor of Electrical
Engineering since 1987, and a joint appointment with the Institute for Systems
Research since 1988. He is also a member of the Applied Mathematics Faculty.
Krishnaprasad has held visiting positions with Erasmus University
(Rotterdam); the Department of Mathematics, University of California, Berkeley;
the University of Groningen (the Netherlands); the Mathematical Sciences
Institute at Cornell University; and the Mechanical and Aerospace Engineering
Department at Princeton University.
Krishnaprasad's research interests lie in the broad area of geometric
control theory and its applications. His contributions include geometry
of parametrization problems in linear systems, the Lie algebraic foundations of
certain nonlinear filtering problems pertaining to system identification, the
Lie theory and stability of interconnected mechanical systems (e.g., spacecraft
with elastic attachments, spinning rotors, and fluid-filled cavities), and symmetry
principles in
nonlinear control theory. He has also investigated mathematical problems in
the kinematics and control of robot manipulators, the real-time control of
flexible robot arms with end-point sensing, tactile perception, and the
development of symbolic algebraic tools for design and control. In the last
several years, his interests have drawn him to: problems of modeling,
design, motion planning and control, arising in mobile robotics (legged and wheeled
vehicles, autonomous underwater vehicles and autonomous aircraft);
geometric methods in nonlinear dynamics;
wavelet analysis for signals and systems; intelligent
control architectures, in part inspired by biological paradigms such as central
patterns generators and neural networks; the technology and theory of smart materials
such as piezo-electric and magnetostrictive materials for use in actuation
and sensing; problems of integration of actuators and sensors in control networks;
and modeling, simulation, monitoring and control in semiconductor
manufacturing processes, such as rapid thermal chemical vapor deposition.
A central interest in geometric control theory, geometric mechanics,
Lie
groups, and distributed parameter systems, guides the technical approaches
taken to attack problems in the above areas. Additionally, some of this work is also
linked to the experimental efforts in the
Intelligent Servosystems Laboratory.
P. S. Krishnaprasad was elected a Fellow of the IEEE in 1990 for his contributions to
geometric and nonlinear control and engineering education. He was appointed
a 1998-2000 Distinguished Faculty Research Fellow of the University of Maryland.
He was a member of a team recognized by American Helicopter Society's
Grover E. Bell Award (2002) (for work on smart structures during 1991-96)
bestowed on the Alfred Gessow Rotorcraft Research Center. He was the Munich Mathematical Colloquium Lecturer (October 24, 2006). He is the recepient of the
2007 Hendrik W. Bode Lecture Prize of the IEEE Control Systems Society, for distinguished contributions to control systems science and engineering. He will
deliver the Bode lecture at the IEEE Conference on Decision and Control, on
December 14, 2007.
