Research on Robust Tracking Control of Networked Control Systems

This paper is concerned with the robust state tracking control of networked control systems. The random transmission delay of network is converted into uncertainty of discrete control system by giving some assumptions. Based on the uncertain discrete linear system, a sufficient condition for tracking errors asymptotic stability of the closed-loop control system is presented by constructing Lyapunov function. Linear matrix inequality (LMI) approach has been employed to obtain the robust tracking controller gain matrix such that system state asymptotically track to a given reference state. A simulation experiment shows the proposed control method is feasible and has satisfactory tracking result.
