Abstract

This talk presents a new supervisory control scheme, which is based on a control-relevant switching logic. Unlike most of the existing switching methods considering only estimator performance, the proposed scheme takes both estimator and controller performance into account. As an index to the controller performance, an iISS (integral-Input-to-State Stability) Lyapunov function is employed; it is ensured that the Lyapunov function satisfies a certain inequality. This Lyapunov-based switching is then coupled to the state-dependent dwell-time switching developed recently, and the state of the uncertain plant is shown to converge asymptotically. The proposed supervisory control scheme is applied to an input-constrained neurally stable linear plant.

He received the B.Sc. degree, M.Sc., and Ph.D. degrees from Korea University in 1998, 2000, and 2005, respectively, all in electrical engineering (under the supervision of Prof. Tae-Woong Yoon). He was a post-doc. in the Department of Electrical Engineering and Computer Science at Seoul National University, Korea, from March 2005 to February 2006 (under the supervision of Prof. Hyungbo Shim). Since March 2006, he has been a post-doc. at IST, University of Stuttgart. Dr. Kim's research interests include switching adaptive control, Model Predictive Control, and Systems Biology.
