| 摘 要： | 针对一类连续非线性时滞系统,在状态不完全可测的情况下,研究了带有传感器故障的容错控制问题。采用T-S模型对非线性系统进行模糊建模,通过构造广义系统设计了观测器,同时估计出系统的状态与故障,进一步利用平行分布补偿算法（PDC）设计基于观测器的模糊容错控制器,给出了保证该模糊容错控制系统稳定的充分条件。仿真例子进一步验证了所提出方法的有效性。

| Abstract: | Against a class of nonlinear continuous system with time delay and sensor failure,the T-S fuzzy model was adopted for fuzzy modeling of the nonlinear system,in the case of state variables unmeasured,observers were designed through constructing a generalized system.At the same time the state and the faults were estimated for the system,a reliable observer-based controller was proposed by（PDC） method,a sufficient condition for the stability of the closed-loop system controller was given.Simulation examples are given to have illustrated the effectiveness of the proposed control approach. |
