摘　　要：基于线性矩阵不等式和控制理论,针对由一组由随机微分方程描述的子系统组成的切换系统,研究此类切换系统在任意切换策略下的鲁棒控制问题,并给出控制器的设计方法。仿真结果表明,所设计的控制器能保证闭环系统在一定意义下的随机稳定。The switched systems under consideration consist-of stochastic equations, firstly, the problem of robust control for uncertain Stochastic Switched Systems under arbitrary switching laws based on LMI is studied, next, sufficient conditions of Stochastic stabilization for switched systems are obtained . The simulation results show that the designed controllers and switching laws guarantee the clcsed - loop systems stochastic stable.
