摘要
We investigate robust fault-tolerant control pertaining to Takagi-Sugeno (TS) fuzzy nonlinear systems with bounded disturbances, actuator failures, and time delays. A new fault model based on a sampled-data scheme that is able to satisfy certain criteria in relation to actuator fault matrix is introduced. Specifically, we formulate a reliable controller with state feedback, such that the resulting closed-loop-fuzzy system is robust, asymptotically stable, and able to satisfy a prescribed H-& INFIN; performance constraint. Linear matrix inequality (LMI) together with a proper construction of the Lyapunov-Krasovskii functional is leveraged to derive delay-dependent sufficient conditions with respect to the existence of robust H-& INFIN; controller. It is straightforward to obtain the solution by using the MATLAB LMI toolbox. We demonstrate the effectiveness of the control law and less conservativeness of the results through two numerical simulations.
