摘　　要：根据点火提前角与怠速转速之间的规律性,并与神经网络控制器CMAC(CerebellarModelArticula-tionController)相结合,提出了基于点火提前角的怠速稳定性控制方法,对燃用LPG单缸汽油机进行了怠速稳定性控制的试验研究。结果表明点火提前角的自动调节对怠速稳定性的控制效果明显,CMAC控制器能有效地用于发动机怠速控制。Based on the regularity between spark advance angle and idling speed, the method of idling speed controlling through spark advance angle combined with neural network CMAC(Cerebellar Model Articulation Controller) controller is proposed. The experimental study on the idling speed stability was conducted in a LPG-fueled single cylinder spark ignition engine. The results showed that the adjustment by spark advance angle on the idling speed was notable, thus, CMAC controller is an effective approach for controlling engine idling speed.
