Abstract :
Combining fuzzy T-S model with adaptive fuzzy logic systems, this paper presents a quadratically stable control scheme for a class of uncertain nonlinear systems. Firstly, the fuzzy T-S model is used to model the nonlinear systems. Secondly, the effect of the modeling errors a and the modeling errors and the uncertain nonlinear parts are eliminated by a compensator based on the adaptive fuzzy logic systems. The control scheme guarantees the quadratic stability of the closed loop system and the L2 norm bound. The simulation results demonstrate that the control scheme is effective.
