摘要：
This study deals with (Q, S, R)gamma-dissipative output feedback control design for a class of switched systems with time-varying delay and unmeasurable states. The purpose is to design an observer-based controller and a switching rule to ensure both exponential stability and strict dissipativity of the resulting closed-loop switched systems. Using an augmented switched Lyapunov-Krasovskii functional with triple sum and the improved reciprocally convex combination approach, new sufficient conditions are developed in terms of linear matrix inequalities. Simulation examples are included to demonstrate the validity and effectiveness of the proposed design technique.
