摘要
结合小排量电喷发动机的结构特点,设计了怠速工况的模糊控制系统。利用遗传算法对模糊隶属度函数进行优化,根据优化参数得到最优模糊控制器。在发动机试验台上对基于经验参数的模糊控制系统和最优模糊控制系统怠速工况下转速变化进行了测试,绘制了速度输出曲线。研究表明,最优模糊控制系统具有较好的控制效果。
A fuzzy controller of idle speed is designed according to structural characters of EFI engine. Optimizing fuzzy congtroller is designed according to paramerers of membership function which is optimized by Genetic Algorithm. Output speed of expert fuzzy controller and optimizing fuzzy controller is measured using engine testbed. Speed ctn＇ve is drawn, which shows that optimizing fuzzy control of idle speed has better effect.
