ECE Colloquium: Hyungbo Shim (Seoul National University) – “State Observer Design for Hybrid Dynamical Systems by Gluing Domains”
Speaker : Hyungbo Shim
Hybrid dynamical system is a system that can be modeled by continuous-time differential equation with discontinuous state jumps. A typical example is a bouncing ball on the floor, or a jumping robot. Systematic analysis and control of hybrid dynamical systems is considered to be relatively new area in control system community.
In this talk, we propose a new state observer design approach for a class of hybrid systems. The idea is to glue the jump set (a part of domain where the jumps take place) onto its image. Then, on the glued domain, the hybrid system becomes a continuous-time system without any jumps. Therefore, it would be possible to design classical observers.
By way of the proposed method, I would also like to justify the phrase “there is nothing more practical than a good theory” (Kurt Lewin).
Hyungbo Shim received his B.S., M.S., and Ph.D. degrees from Seoul National University, Korea, in 1993, 1995 and 2000, respectively. From 2000 to 2001 he was a post-doctoral researcher at the Center for Control Engineering and Computation, University of California, Santa Barbara. In 2002, he joined Hanyang University, Seoul, Korea. Since 2003, he has been with Seoul National University. His research interests include analysis and control of nonlinear systems with emphasis on observer design. He is an Associate Editor for Automatica, and a former Associate Editor for IEEE Transactions on Automatic Control, International Journal of Robust and Nonlinear Control, and European Journal of Control. He served as the vice IPC chair for IFAC World Congress in 2008, and the program chair for Int. Conf. on Control, Automation, and Systems in 2014. He is now the director of Engineering Research Center for Advanced Control and Instrument.
