Abstract :
Gasoline engine idling instability is a common problem of engine idling control system. In order to improve steady and dynamic characteristics of gasoline engine idling control, a new type compound fuzzy-PID control system was designed and compared with the traditional PID system through simulation by MATLAB/ Simulink and test in dynamometer. The results confirm that the compound fuzzy-PID control system can decrease remarkably idling speed fluctuation, the maximum transient ripple value is still less than 15 r/ min with the air-conditioner load added and it has an enough robustness so that it is suitable for actual vehicles.
