The invention proposes a PID-based iterative learning control method based on a neural network, belonging to the field of control science and engineering. For a general nonlinear difference system, the invention gives an iterative learning PID controller, and then dynamic parameters in the PID controller are fitted by using three RBF neural networks. The weights of the neural networks are estimated according to a gradient descent method and a neural network weight update expression is obtained. Since an exact model of a controlled system is complex or unknown, a real value of a system pseudo partial derivative (PPD) in a neural network weight estimation expression cannot be obtained, and an estimated value is used for numerical value substitution. In this way, a nonlinear iterative learning control algorithm that can be run is generated. Finally, an example is given to demonstrate that the numerical simulation of the algorithm in a nonlinear system and a picking and placing robot system is effective. Therefore, this algorithm can be applied to a general (unknown) nonlinear differential system.
