Reliable H221E; Control for T-S fuzzy systems with time varying delay and actuator faults

This paper is concerned with the design of reliable H221E; fuzzy controller for continuous-time nonlinear systems with time delay and actuator faults. Based on a parameter-dependent Lyapunov Function and general actuator failure (which covers the cases of normal operation, partial degradation and outage), a novel design method of reliable fuzzy controller for T-S Fuzzy system with time varying delay is proposed. The corresponding closed-loop system is asymptotically stable not only when all actuator components are operating well, but also in the presence of some actuator failures. Sufficient conditions are proposed in Linear Matrix Inequality (LMIs) terms by employing different model transformations and techniques. Simulation example shows the effectiveness of the proposed method.
