电机PID闭环系统在智能小车上的应用

Application on Motor PID Closed-loop System in Smart Car

“恩智浦杯”全国大学生智能汽车竞赛对智能车的稳定性及速度都有较高的要求,因此通过一套完善的PID闭环控制系统来实现对车模的速度进行精准地控制显得极其重要.该文提出基于欧姆龙编码器与PID算法相结合的闭环控制系统,实现对智能小车速度的精准控制.通过实验证明,该系统的设计方法简单且效果明显,能够更好地对小车的速度进行精确控制.

The "NXP Cup" national college student smart car competition has high requirements for the stability and speed of the smart car.Therefore,it is extremely important to achieve precise control of the speed of the car model through a complete PID closed-loop control system. This paper proposes a closed-loop control system based on the combination of Omron encoder and PID algorithm to achieve precise control of the speed of the smart car.The experimental results show that the design method of the system is simple and effective,and it can better control the speed of the car.
