Abstract: The paper gave an PID-type iterative learning control algorithm with initial state study aiming at a class of nonlinear system running repeatedly in limited interval.Operator theory proves the validity of the algorithm.The algorithm not only solves initial state problem of the iterative learning control,but also relaxes the convergence conditions.Results of comparing the simulation analysis of PID-type iterative learning control algorithm with the simulation analysis of PD-type iterative learning control algorithm show that the tracking accuracy of nonlinear system in the initial state conditions is significantly improved after PID-type iterative learning,and the output error curve tends to zero more quickly.The results illustrate the effectiveness of the algorithm.
