Abstract:

H∞ and H2/H∞robust control for a class of switched discrete systems with parameter uncertainty and external disturbance are studied. Firstly, stability and H∞ control performance of the switched systems under consideration with state feedback controller are presented, based on multiple Lyapunov function method. Secondly, the convex optimization problem is established for H-2/H∞ control and its optimization solution is given which has smaller conservative property. The simulation further verifies the feasibility of the proposed scheme posed.
