基于模糊控制的燃油泵系统建模与仿真

Modeling and Simulation of Fuel Pump System Based on Fuzzy Control

建立了无刷直流电动机(BLDCM)、离心泵和模糊控制器的模型,并将其有机组合构建了BLDCM驱动的燃油泵系统的模糊控制仿真模型,设计了基于流量的燃油泵转速闭环,并进行了仿真,仿真结果显示:采用模糊控制系统上升时间短,无超调,无震荡,无稳态误差,比PID控制具有更快的动态响应和更好的稳态特性。

This paper established models of BLDCM,centrifugal pump and fuzzy controller,then established a model of fuel pump system drived by BLDCM based on fuzzy control.Designed a flow loop,then made simulation.The simulation results show that the fuzzy controller has no overshoot,no concussion and no steady-state error.It has faster dynamic response and better Static characteristics than PID control.
