摘　　要：针对柴油机全气缸取样系统对试验缸电控燃油喷射的特殊要求及喷油压力模型难以确定的特点,采用模糊控制方法,对电控燃油喷射系统的喷油压力进行控制研究。将所设计的控制算法应用于全气缸取样试验单缸机,结果表明,喷油压力在20-120MPa范围内任意可调,且具有较强的鲁棒性和较高的稳定性,取得了良好的控制效果。By using fuzzy control method,the injection pressure electronic control system was studied for an electronically controlled diesel total cylinder sampling system.The fuzzy controller was designed based on control strategy of injection pressure and character of injection.The experimental results indicated that the control system of injection pressure was flexible and reliable in 40-120MPa and good adaptability and stability of the control algorithm were achieved.
