This paper analyzes the iterative learning control, and utilizes the theory of iterative learning control to study using PID open-loop iterative learning control algorithm to track the ordered curves for a class of the nonlinear problems which are exist actually in some control systems. According to the theory of full trace in the control of practical tracking, these experiments fully track a nonlinear system. With the increasing number of iterations, the output signal is closer to the expected signal. Finally we concluded that the PID open-loop iterative learning control algorithm is applied to such issues by analyzing the process of the simulation and the results of the simulation.
