研究一类执行器可能发生部分故障的不确定多时滞离散切换系统的滑模可靠控制问题。针对每个子系统设计相应的拟积分型切换面,保证系统状态轨迹从开始时刻就位于切换面上。利用Lyapunov稳定性理论和线性矩阵不等式技术给出滑模动态系统鲁棒渐近稳定的充分条件,进而给出可实现的滑模可靠切换控制器的设计方案。最后用仿真例子说明设计方法的有效性。 This paper studies the problem of sliding mode reliable control of uncertain discrete-time systems with multiple delays that may occur in partial actuators. For each subsystem designed the corresponding quasi-integral type switching surface, to ensure that the system state trajectory from the beginning on the switching surface. By using the Lyapunov stability theory and the linear matrix inequality technique, sufficient conditions for the robust asymptotic stability of the sliding mode dynamic system are given. Then a design scheme of the reliable sliding mode switching controller is given. Finally, simulation examples illustrate the effectiveness of the design method.
