Because the driver's speed control system is a system with strong time-varying and large variation of parameters, in order to simulate the change rule of the driver's speed, this paper establishes the BP neural network PID model. In this paper, a three-layer BP neural network is designed and compared with the simulation curve of the speed variation of the classical PID control and the Speed variation simulation curve of the PID control of the BP neural network in the PID control system. The simulation results of this paper show that the BP neural network PID controller designed in this paper shows good control effect in the performance dynamic following, real-time and robustness.
