H∞ control for parameter uncertain T-S fuzzy systems with time-delay in state and control input

This paper focuses on the problem of H^∞ fuzzy control for a class of nonlinear uncertain delay systems in both state and control input through Takagi-Sugeno (T-S) fuzzy model approach. Sufficient conditions for the existence of H^∞ state feedback controller for the systems are presented on the basis of the linear matrix inequalities(LMIs) approach. Design example of robust H^∞ controller is given to illustrate the effectiveness of approaches proposed in this paper.
