State feedback H/sup /spl infin// controller design of fuzzy dynamic systems using LMI techniques

This paper presents robust H/sup /spl infin// controller design for fuzzy dynamic systems with state feedback. Three kinds of controller design methods are proposed, and the boundary conditions are given when the controller designs are considered based on a piecewise smooth Lyapunov function. The control laws are obtained by using LMI techniques and the global stability with disturbance attenuation of the closed-loop fuzzy control system is established.
