Using of the electric motor control system and the principle of rolling plastic deformation, this paper describes the stable state mathematical model of cold rolling process is established. The dynamic process of cold rolling is simulated by using the MATLAB/ Simulink. Cold rolling control system exists time-delay, time-varying, large inertia, nonlinear and other problems. Setting parameters of traditional PID controller is difficult. This paper put forward a method which combines structure of a fuzzy control and PID control. By MATLAB simulating, results show that static and dynamic performance of fuzzy adaptive PID controller is better than the traditional PID controller.
