| Abstract: | The problem of robust stabilized control for a class of switched hybrid systems with unknown nonlinear disturbance is studied.Based on sliding mode control techniques,a decentralized output feedback robust control scheme is proposed.The sliding mode reachability condition is given.And output feedback sliding mode controller for each sub-system is designed.Furthermore,according to the values of Lyapunov function and state variables,the switching strategy is submitted to guarantee the asymptotic stability of the closed-loop system.Simulation results demonstrate the effectiveness of the proposed approaches. |
