Fuzzy decentralized output feedback control for a class of nonlinear interconnected systems with time-delay

An observer based on fuzzy decentralized control method for a class of nonlinear interconnected systems with time-delay is proposed. An equivalent T-S fuzzy model is applied to the fuzzy modeling of the nonlinear interconnected system with time-delay , then the fuzzy decentralized observer and fuzzy decentralized controller are designed. The sufficient conditions for the stability of the fuzzy decentralized system with time-delay are proposed by using Lyapunov function combined with linear matrix inequalities (LMIs). Finally, the simulation results show the effectiveness of the proposed methods.
