Professor, Department of Mechanical/Aerospace Engineering

Organization: University of California, San Diego

Biography:

Miroslav Krstic received his Ph.D. in electrical engineering from the University of California, Santa Barbara, in 1994. After two years as assistant professor of mechanical engineering at the University of Maryland, he joined UCSD in 1997. Krstic presently holds the Daniel L. Alspach chair in Dynamic Systems and Control and is the founding director of the Cymer Center for Control Systems and Dynamics. Krstic has held the Russell Severance Springer Distinguished Visiting Professorship at UC Berkeley and the Harold W. Sorenson Distinguished Professorship at UC San Diego. He is a recipient of the PECASE, NSF Career, and ONR Young Investigator Awards, as well as the Axelby and Schuck Paper Prizes. Krstic was the first recipient of the UCSD Research Award in the area of engineering. He is a Fellow of IEEE and IFAC and serves as Senior Editor in IEEE Transactions on Automatic Control and Automatica. He has served as Vice President of the IEEE Control Systems Society.

Abstract:

Control over networks creates a need for feedback strategies that compensate significant delays in actuation and sensing. In the presence of state-dependent delays, the challenge is not only that the state is infinite-dimensional and the delay is timevarying, but also that the horizon for compensating the delay is not known a priori and the delay rate becomes dependent on the input. The speaker will present solutions to the problem of stabilization in the presence of state-dependent delays for general linear and nonlinear systems. For constant delays, the presenter will introduce sampled-data nonlinear controllers that compensate delays of arbitrary length, under arbitrarily sparse sampling. Illustration will be provided through several examples, including stabilization of the nonholonomic unicycle.
