摘要: 通过对汽油机怠速工况的分析,采用PID与模糊控制相结合的复合控制策略,即在大偏差范围内采用模糊控 制,小偏差范围内转换成PID控制,使系统在较大误差时追求速度,在较小误差时强调精度。仿真结果表明:该控 制策略使系统实现了快速、平稳、无误差跟踪的特性,怠速工况的控制精度大为提高,系统的控制品质大为改善。

Abstract: Based on analysis of petrol engine idling working condition, mixing up methods of PID and fuzzy controlling were employed. If there was large deviation, fuzzy control could be applied; if not, PID control should be employed. In this way, speed could be achieved when there was big error; accuracy could be guaranteed when there was small error. Simulation results indicated that speed, stability and accuracy were realized; accuracy under idling working condition and quality of the system were improved.
