摘要：

For discrete-time Takagi-Sugeno (TS) fuzzy systems, we propose an H-infinity state-feedback fuzzy controller associated with a fuzzy weighting-dependent Lyapunov function. The controller, which is, designed via parameterized linear matrix inequalities (PLMIs), employs not only the current-time but also the one-step-past information on the time-varying fuzzy weighting functions. Appropriately selecting the structures of variables in the PLMIs allows us to rind an LMI formulation as a special case.
