<正>设计了汽油发动机怠速动态矩阵预测控制 (DMC)系统 ,用已建立的发动机怠速控制的数学模型和DMC算法 ,对发动机怠速速度予以控制。结果表明 ,DMC算法适用于发动机怠速控制 ,且具有稳定性好 ,抗干扰强等优点。

This paper gives a DMC system for idle speed of a gasoline engine. Engine idle speed can be controled by the model of idle speed and DMC algorithm. The result of engine test shows that the DMC algorithm is adaptable for idle speed control of a gasoline engine and its stable and strong to resist interference.
