| 摘 要： | 研究了一类离散不确定时滞模糊系统的容错控制问题。针对非线性离散系统，构造T-S模型，引入参数不确定项和时滞项，使得模糊模型能够更精确逼近原系统。基于T-S模糊模型，利用Lyapunov方法，证明了所采用的模糊控制律使得闭环模糊系统对于执行器故障以及传赢器故障具有完整性和鲁樟挂。不确定项具有范数有界时，利用求解线性矩阵不等式（LMI）的方法，得出了闭环模糊系统在执行器故障以及传意器故障时具有完整性的充分条件。仿真结果说明了该方法的有效性。 |

| Abstract: | The fault tolerant control design for uncertain discrete fuzzy system with time-delay was investigated by utilizing the fuzzy control method. Constructing T-S model and introducing parametric uncertainty and time-delay terms for nonlinear discrete systems, there made the fuzzy model approach to the original system more exactly. Based on T-S fuzzy model, the possessing integrity and robustness for actuator failure and sensor failure to closed-loop fuzzy system which used fuzzy control law was guaranteed by using Lyapunov method. The sufficient conditions for the closed-loop fuzzy system possess integrity against actuator failures and sensor failures were derived in terms of linear matrix inequalities (LMI) when there existed the bounds for uncertainties. The simulation results illustrate the effectiveness of the proposed approach. |
