Abstract :
The H∞ state feedback control problem for networked control systems of 2-DOF ceramic manipulators with disturbances was studied. At first, a networked robust control model of ceramic manipulators is made. Then, sufficient conditions of H∞ robust stability is given for networked control systems of ceramic manipulators under the maximum network time-delay condition. In addition, the state feedback control law were proposed by using the linear matrix inequality method. In the end, a simulation is given. Simulation results show that the networked H∞ robust control strategy proposed can effectively attenuate perturbations of ceramic manipulators based on networked control systems, and render the closed loop system stable.
