Non-fragile Fault-Tolerant Guaranteed Cost Control for Uncertain T-S Fuzzy Systems

This paper proposes a new non-fragile fault tolerant guaranteed cost controller design method for a class of Takagi-Sugeno (T-S) fuzzy uncertain systems with state-delay. Two sufficient conditions for the asymptotic stability of the closed-loop fuzzy system in actuator failure have been derived under the condition that the controller uncertainties are additive and multiplicative, and the sufficient conditions are presented in terms of a set of linear matrix inequalities (LMIs). The simulation results demonstrate the effectiveness of the proposed method.
