Abstract
This paper is concerned with fault-tolerant control (FTC) for a class of nonlinear discrete-time systems. A dynamic output feedback controller is designed for Takagi-Sugeno (T-S) fuzzy systems with state and input parameter uncertainties, exogenous disturbances, measurement noise and multiple intermittent faults. Compared with the existing research results, the proposed controller has a wider application range. The stability of the closed-loop systems is guaranteed by H∞ performance and sufficient conditions are proposed for the considered system with multiple sensor faults, multiple actuator faults, multiple sensor and actuator faults, respectively, by solving linear matrix inequalities (LMIs). Finally, two numerical examples are provided to demonstrate the effectiveness of the proposed FTC method in the paper.
