The Grey Forecasting Control for the Fuel Supply System of LPG Automobile

介绍液化石油气汽车燃料供给系统的组成结构 ,以灰色系统思想和灰色模型为基础 ,对发动机的空燃比进行预测 ,并以此控制液化石油气的供给量。文中还给出了灰色预测控制系统电控单元的硬件设计原理 ,实验结果表明 。

This paper describes the primary principle and structure of the fuel supply system for Liquid Petroleum Gas (LPG) automobiles Based on the grey system idea and grey model, the air?fuel ratio of the engine is forecasted The mass of LPG which flows into the engine is controlled according to the value of air?fuel ratio. The procedure of grey forecasting control aigorithm is presented.The hardware design of the grey forecasting electronic control unit is also introduced.Meanwhile,the anti?interference method is described for improving the system reliability The experimental results show that the algorithm of grey forecasting control for the fuel supply system can achieve ideal control effect
