摘　　要：柴油机燃油喷射的控制高精度、响应快速度是保证其燃油经济性、排放清洁性的基本要求,所以本文利用智能权函数的改进模糊控制方法来实现对燃油系统的快速、精确控制,并对燃油压力阶跃升高控制进行仿真。仿真结果表明,该改进模糊控制方法相对PID控制而言,具有更好的控制稳定性和时效性,是一种具有广泛应用前景的智能化控制方法。The high precision and quick response of fuel injection control is the postulate to achieve fuel economy and exhaust cleanness, so an improved fuzzy control method with intelligent weight function was used to control the fuel system quickly and accurately. According to the simulation of control for the step hoist of fuel pressure, it indicates that this method has better control stability and speed. It＇s an intelligent control method with wide application foreground.
