Improved criteria for the stabilization of T-S fuzzy systems with actuator failures via a sampled-data fuzzy controller

This paper studies a problem of the sampled-data stabilization for Takagi-Sugeno fuzzy systems with actuator failures. An improved Lyapunov functional is constructed, which is dependent on the fuzzy membership functions FMFs and includes the sampling states with two sampling instants. A new integral term including the FMFs is introduced into this Lyapunov functional for the first time. Each term in this Lyapunov functional need not be positive,...
