T-S Fuzzy Controller in Consideration of Input Constraint

This paper deals with stability analysis and control de- sign for a class of nonlinear systems with input constraint when using T-S fuzzy model. After leading the control de- sign to LMIs approach, the attention is paid to 1) how to easy the LMIs conditions so that the system is asymptoti- cally stable in a so-called ellipsoid to be made as large as possible; 2) how to relax the LMIs conditions so that the LMIs problem is more feasible.
