摘　　要：本研究针对船舶双燃料发动机燃料低压供储气系统的燃料泵控制,提出一种改进后的PID调节算法的控制算法,满足各工况下双燃料发动机供气压力及流量要求。在样机台架试验过程中,对比经典PID控制方法和该算法控制的燃料泵后端压力等,该方法输液稳定,确保缓冲罐压力平稳,控制精度高,反应时间快,超调量小。Aiming at the fuel pump control of the low pressure gas supply and storage system of the marine dual fuel engine,this paper proposes a PID control algorithm to meet the requirements of the fuel supply pressure and flow of the dual fuel engine under various working conditions.During bench test of the prototype,the fuel pump controlled by the algorithm has stable fluid,stable pipeline pressure,high control accuracy,fast response time and small overshoot.
