| 摘 要： | 研究了非线性系统中部分执行器可能失效的T—S模糊系统的容错控制问题。基于新的稳定性条件，采用线性矩阵不等式的方法，得出了系统在执行器故障时控制器存在的充分条件。在此条件下所设计的控制器，不仅使闭环系统渐近稳定而且具有适当的性能指标。仿真结果表明了该方法的有效性。

| Abstract: | The problems of fault-tolerant control for T-S fuzzy system with possible actuator failure were studied.Based on the new stability condition,a sufficient condition for the existence of fault-tolerant controller was given by using the method of LMI while actuators were of fault.Under the condition,the designed controller not only provided the asymptotical stability of the closed-loop system but also guaranteed the performance at an adequate level.The simulation results expatiated the validity of this method. |
