Design of flow controller for aviation electric fuel pump

In order to meet the demand of high-precision flow control and modular design of aviation electric fuel pump control system, the flow controller is analyzed and designed from the demand of aviation engines for electric fuel pump. Tests show that the steady-state control deviation of the controller is no more than 1% for mass flow rate, and the dynamic control deviation of mass flow rate is no more than 3% in the range of 50kg/h~2000kg/h. A flow controller with high integration degree, high control accuracy and excellent dynamic characteristics for new pump-control system was designed for aero engine.
