Research Abstract |
In this study we dealt with robust semidefinite programming problems (robust SDPs) that naturally appear when we analyze robust performance of control systems affected by parametric uncertainties. For the robust SDPs, we successfully constructed a sequence of SDPs that is ensured to be asymptotically exact. On the other hand, to achieve better robust performance for uncertain discrete-time systems, we conceived a novel memory-type periodically time-varying controller structure and established a concrete way to design such controllers by means of SDPs. Dr. Yoshio Ebihara received SICE Annual Conference International Award for his paper dealing with robust performance analysis of uncertain discrete-time systems.
