Abstract:In this paper, the passivity property is applied to stability analysis, controller synthesis and observer design of the discrete affine Takagi-Sugeno (T-S) fuzzy systems. A fuzzy controller is designed to achieve Lyapunov stability of system and strictly input passivity for all exogenous disturbances. The proposed fuzzy controller design approach is developed based on the Parallel Distribution Compensation (PDC) technique. Moreover, an Iterative Linear Matrix Inequality (ILMI) algorithm is applied to solve the feasible solutions for the proposed observer feedback fuzzy control problem. Finally, the application of present approach is illustrated by a numerical example.
