Robust Mixed H2=H∞ Output Tracking Control of Uncertain Discrete-Time Switched Systems with State Time-Delay
Author:
Abstract: This paper focuses on the problem of mixed H2/H∞ output tracking control for uncertain discrete-time switched systems with state time-delay. By using single Lyapunov function theory, a state feedback controller is presented to guarantee the closed-loop error system robust asymptotically stable with mixed H2/H∞ performance is developed. The controller gains are obtained by a set of linear matrix inequalities(LMIs). The corresponding stabilizing switching rule is provided. A numerical example is given to demonstrate the effectiveness of the pro- posed approach.
