| 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. |
