EFI系统自学习模糊控制的研究

本文提出了一种电子汽油喷射系统的智能控制方案－自学习模糊控制，自学习控制通过对燃油喷射脉冲宽度的调控，使发动机在运行的全过程中始终在保证动力性的基础上达到油耗最低的最佳或满意状态，自学习控制中喷射脉宽的增量是由模糊控制来确定的，实验证明，该智能控制系统改善了发动机的性能。

Study on Self-learning Fuzzy Control of EFI System

This paper puts forward a scheme of Intelligent Control of Electronic Fuel Injection (EFI) System-the self- learning fuzzy control. The scheme keeps the engine at optimum state in all operation modes, namely,minimizes the fuel consumption while maintains output power needed by changing the injection pulse width, whose increments are determined by fuzzy control. Test result shows that the control system has improved the performance of the engine.
