| 摘 要： | 研究了一类具有时滞不确定性系统的鲁棒容错控制问题,针对既有传感器失效,又有执行器失效的故障情形,通过引入一种无记忆的状态反馈控制器,基于Lyapunov稳定定理和运用线性矩阵不等式(LMI)的方法,给出了在传感器失效和执行器失效故障下具有鲁棒完整性的充分条件,并进行了证明。最后利用Matlab中的LMI工具箱进行了算例仿真,证实了这种设计方法的有效性和可行性,减少了当出现故障时需要先判断哪类故障的任务,为容错控制提供了便利。

| Abstract: | The problem of robust fault-tolerant control for the uncertain time-delay system is studied.The considered system has sensor and actuator failures.Based on Lyapunov stability theory and linear matrix inequality(LMI),a method of robust fault-tolerant against sensor and actuator failures for uncertain system was proposed via memoryless state feedback control law.The sufficient conditions for the closed-loop system possessing integrity against sensor and actuator failures are given,and it is proved.At last,the... |
