Abstract: Aiming at the performance degradation of uncertain time-delay networked control system, this paper proposes stability condition and the sufficient condition of H performance criterion based on Lyapunov function and Linear Matrix Inequality(LMI), and applies the result in designing the controller of Internet-based arm wrestling contest control system. Practice indicates that the algorithm can improve the performance of the networked control system.
