摘要
应用模糊控制方法对汽油机怠速进行了研究,此方法的显著特点是不需要对控制目标建立精确的数学模型。应用模糊控制的怠速实验结果与开环怠速控制的实验结果进行了对比,结果表明怠速模糊控制方法应用于发动机怠速控制是可行的,而且比开环控制更加有效。
オn this paper, fuzzy control method has been used to study engine idle speed. This method has advantage in not making a mathematical model for the controlled object. The proceedings of idle speed are so complex that it is very difficult to design a good controller based on the mathematical model of gasoline engine idle speed. But it is practical for an experienced drivers to control that well by the method of adjusting air intake or preignition angle. Fuzzy control method is just based on the knowledge base which takes its source at the experienced drivers. The experimental results obtained with this method prove that fuzzy control method is practical. Compared with an open loop control, fuzzy control is more effective. Idle speed quality is improved highly. Speed wave is decreased. Improvement of idle speed stability is obtained.
