摘　　要：结合对发动机管理系统中发动机怠速控制系统的研究,分析了数字PID控制的控制原理以及在发动机管理系统上的体现。对于在目标怠速附近的转速波动控制加以探讨,简化控制模型,采用GA算法整定PID控制器中的比例、积分、微分的控制参数,具有模型简单,效率高的优点。同时在车辆上做了实践指导。Combined with the research of the control system of the engine idling in engine management system, the control principle of digital PID and its application in engine management system is analyzed. The speed fluctuation control near the target idling is discussed, the control model is simplified, and the parameter of proportion, integral and differential in PID controller by GA is adjusted. The model is simple and efficient, and practical guidance is carried out in the vehicle.
