The problem of H∞ control for networked interconnected system with unknown disturbance is discussed. The Takagi-Sugeno (T-S) fuzzy model is adopted for fuzzy modeling of the networked interconnected system, considering the problems of time-delay and data packet dropouts for networked control. According to the Lyapunov stability theory and decentralized control theory of interconnected system, based on LMI method, the paper proposes the sufficient condition that ensures the asymptotic stability and satisfies the H∞ performance. Finally, the numerical example and simulations have demonstrated the validity of the method.
