Application and Simulation Analysis of PID Control Algorithm Based on Integral Separation

In order to solve the environmental problems and traffic safety problems caused by the increasing number of automobiles,It is of great significance to study new energy electric vehicle technology. This paper focuses on the research and analysis of constant speed cruise control of new energy electric vehicle, and the paper uses the patchwork method to design PID control. There is a large overshoot, and the control effect is not ideal. The integral separation PID control algorithm is introduced and simulated in MATLAB, and the control effect is better than position PID control effect.
