摘      要：This study deals with H2 guaranteed cost control problem for discrete time nonlinear systems with parameter *** Takagi and Sugeno（T-S） fuzzy model with parameter uncertainties is employed to represent an uncertain discrete time nonlinear *** on the structural information in rule base,an output feedback controller design method is *** conditions for the existence of H2 guaranteed cost output feedback controllers are *** more,a convex optimization problem with linear matrix inequality（LMI） constraints is applied to design the suboptimal H2 guaranteed cost output feedback controller which minimizes the guaranteed cost of the closed-loop uncertain *** example is given to demonstrate the effectiveness of the proposed method.
