H∞ control for a class of singular networked control systems with input disturbance

This paper investigates the H∞ optimal control problem for a class of singular networked control systems with input disturbance. Aiming at a class of regular singular controlled plant, comprehensive considering network-induce delay, input disturbance, node driving way of network communication and singular system characteristics etc complex factors, a mathematic model of state feedback closed loop system is developed, then asymptotic stability and H∞ optimal control method of the closed loop system are investigated, and the solving method of Hx control law and disturbance attenuation degrees are presented. A simulation example shows that the analysis method and the results are valid and feasible.
