模糊神经网络在发动机怠速控制中的应用

Application of Fuzzy Neural Network in Eng ine Idling Control

讨论了发动机怠速控制方法,对用模糊控制、BP神经网络控制方法进行了深入研究。给出了模糊控制和PID调节在怠速控制上的对比以及BP神经网络用于学习模糊控制器的输入与输出之间的函数关系,以取代模糊控制规则表。在BP网络的训练过程中,采用了自调整的学习算子以加速收敛,并给出了仿真结果。

Engine idling control methods are discussed.Control methods applying fuzzy control and BP neural network control are studied deeply.Comparison between application of fuzzy control and that of PID ad justing in en gine idling control is given.BP neu ral network is used to learn the function relation between fuzzy controller's input and output,which is used to sub-stitute for fuzzy con trol rule list.During train ing of BP neural network,self-adjusting learning operator are used to accelerate its convergence.Sim ulating re sults are given.
