Robust Decentralized Control for T-S Uncertain Fuzzy Interconnected Systems with Time-Delay

Decentralized state feedback control is developed for a T-S fuzzy discrete-time interconnected system with parametric uncertainties and time-delay. First, an equivalent T-S fuzzy model represents the discrete-time nonlinear interconnected system with time-delay, then fuzzy state feedback decentralized controller is designed. The sufficient conditions for the stability of the closed-loop system combined with linear matrix inequalities (LMIs) are given. A simulation example illustrates the effectiveness of the proposed approach.
