H/sub /spl infin// controller design for discrete-time fuzzy systems using fuzzy weighting-dependent Lyapunov functions
Tóm tắt
For discrete-time Takagi-Sugeno (TS) fuzzy systems, we propose an H/sub /spl infin// state-feedback fuzzy controller associated with a fuzzy weighting-dependent Lyapunov function. In terms of parameterized linear matrix inequalities (PLMIs), the controller employs not only the current-time but also one-step-past information on the time-varying fuzzy weighting functions. Appropriately selecting the structures of variables in the PLMIs allows us to find an LMI formulation as a special case.
