摘　　要：研究一类Delta算子切换系统的鲁棒可靠控制问题。首先基于多Lyapunov函数和平均驻留时间方法,以线性矩阵不等式的形式给出了参数不确定Delta算子切换系统指数稳定性条件,然后通过对执行器故障建模,进一步给出Delta算子切换系统鲁棒可靠控制器存在的充分条件和设计方法,所设计的鲁棒可靠控制器能保证系统参数不确定时闭环系统指数稳定。仿真结果证明了设计方法的有效性和可行性。The problem of robust reliable control for uncertain switched systems using Delta operator is studied. Firstly,based on multiple Lyapunov function theory and average dwell time, a sufficient condition for the existence of stability of the parameter uncertain Delta operator switched system is presented in terms of LMI .Then, Through fault modeling, a sufficient existence condition and designing method of robust reliable controller for Delta operator switched system are proposed. The reliable controller that designed guarantee the closed-loop system with uncertain parameter to be exponentially stable. A simulation example is given to illustrate the effectiveness and feasibility of the proposed method.
