Abstract: 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.
