电控汽油机怠速控制方式

Idling Control Schemes for Electronically Controlled Gasoline Engine

针对怠速工况分别设计了变参数PID控制系统和模糊控制系统 ,并进行了实车试验对比。结果表明 ,怠速工况下 ,模糊控制方式比PID控制方式转速波动小 ,控制效果好。

In this paper,both PID controller with variable parameters and fuzzy logic controller for idling model are designed and evaluated by field tests on a production vehicle It is shown that in idling mode,the fuzzy logic control is better than the PID control in lower speed fluctuation and more effective control
