Abstract :
The generalized stabilization and the controller design problems are studied for a class of continuous nonlinear systems described in T-S fuzzy model, which has uncertainties in state and input, The non-fragile fuzzy controller is designed based on piecewise Lyapunov function theory, PDC and Linear Matrix Inequation method, which ensure the asymptotically stability and the performance of the resulting closed-loop systems for all admissible uncertainties. The simulation is presented to show the feasibility and effectiveness of the proposed method.
