摘要 为提高动态系统的可靠性,研究了带有执行器故障的变时滞不确定系统的鲁棒可靠控制.给出了系统在正常运行和带有可预期执行器故障情况下,闭环系统保持二次稳定的时滞依赖充分条件.运用线性矩阵不等式方法实现了可靠状态反馈控制的综合问题.通过仿真算例,说明了本文方法的可行性和有效性. The robust reliable control well as actuator failures in the input that the closed-loop system quadratic possible actuator failures. The condit synthesized within the framework of efficacy and validity of the approach. design problem for uncertain systems with time-varying state delay as channels was discussed. A sufficient condition was established such stability is satisfied for both the normal system and the system with ion is a delay-dependent one. A reliable state feedback controller was linear matrix inequalities. The simulation results demonstrate the
