| 摘 要： | 研究了不确定时滞非线性混沌的鲁棒容错控制问题.基于Lyapunov泛函,运用线性矩阵不等式(LMI)的方法,利用不稳定不动点的控制,引入一种带时滞的状态反馈控制律,对传感器或执行器失效的情况,证明了一类非线性不确定时滞混沌系统对于传感器和执行器故障都具有完整性.结果表明,所给出的控制律不但可以实现对某些传感器故障的容错,而且在正常和故障情况下对于传感器和执行器故障都具有完整性.

| Abstract: | Based on Lyapunov method and linear matrix inequality(LMI),a kind of state feedback controller with time-delay is presented and the sufficient conditions for the closed-loop system possessing integrity against sensor and actuator failures are given.The results show that the proposed controller accomplishes the fault tolerant for some sensor failures,in addition under normal and failure conditions it possesses integrity against sensor and actuator failures. |
