Hydraulic automatic gauge control (AGC) is a very important part of rolling mill for magnesium plate rolling. The control effect of automatic gauge control system influences the quality of the rolled product directly. AGC system is an essentially nonlinear, time delay, time-varying, large inertia, multivariable and coupling complex system, which increase the designing difficulty of control system. Based on the mathematical model of the automatic gauge control system, a simulation platform of rolling mill is set up, and a sliding mode variable structure controller is designed to realize position control for the hydraulic automatic gauge control system. The control effect of the proposed sliding mode controller is compared with that of a general PID controller whose parameters was adjusted by Ziegler-Nichols method. Simulation results show that the sliding mode controller has strong anti-interference ability and can give satisfactory control effect.
