Abstract

This paper concerns the decentralized dynamic output feedback control for nonlinear interconnected systems with time delay in the discrete time case. We use Takagi-Sugeno (T-S) fuzzy model of nonlinear interconnected system. Based on T-S fuzzy interconnected system, the decentralized dynamic output feedback controller is design. For stabilization of interconnected systems, sufficient conditions are derived for control gains and expressed as the linear matrix inequalities (LMIs). A numerical example is given to show the verification of the proposed methodology.
