摘　　要：本文阐述了发动机空燃比控制的研究现状及发展趋势 ,介绍了基于神经网络及模糊控制的智能PID控制、带有调节因子的模糊控制等控制方法 ,并具体讨论了CMAC模型人工神经网络在空燃比控制中的应用 。This paper explicates the R&D status and trend of the A/F ratio control for engines. The control techniques of intelligent PID controller based on neural networks and fuzzy theory, and of fuzzy control with self adjusted factor are introduced. The application of CMAC model of artificial neural networks for A/F ratio control is discussed detailedly. The applicative perspective of modern control techniques for A/F ratio control on engines is indicated.
