说明：  基于PID控制，利用matlab编写车队运动程序，设计模型中车辆间距离会随着车速的变化而变化，可以保持车队运行的稳定。可根据实际情况稍作更改。
(Based on PID control, using MATLAB to write the team movement program, the distance between vehicles in the design model will change with the change of vehicle speed, which can maintain the stability of the team operation. It can be changed slightly according to the actual situation.)
