汽油机怠速控制策略研究

摘要

Using self-developed electronic control system, the paper presents the fuzzy control method for idle condition of 479QE engine. The engine dynamometer test indicates; the fuzzy control strategy is a valid idling speed control method . The method can stabilize idle speed at target speed.%用自主开发的控制系统,以479QE发动机为控制对象,对发动机怠速工况的运行采用模糊控制方法进行试验.台架试验表明:采用模糊控制是一种有效的怠速控制方法,能使发动机转速稳定在怠速目标转速.
