【Abstract】 This paper analyzes the structure and principle of the neural network PID controller,the mathematical model of the hoisting system of the excavator, and modeled this system by the Simulink toolbox of Matlab software. Finally this paper describes the step response curve of the hoisting system of the excavator under two kinds of controller. The experimental results show that the control effect of neural network PID controller is better than conventional PID controller.更多还原
