Abstract

As the core component of more electric engine (MEE), electric fuel pump is composed of a permanent magnet synchronous motor (PMSM) integrated with a high-pressure gear pump. Rotation speed is controlled by the motor and the pump discharges the fuel with required amount into the engine combustor. How the speed control system works largely determines the delivery flow rate of the pump, although delivery pressure can disturb the flow rate as well. Hence, it must be capable of delivering the maximum needed flow at appropriate pressure to obtain satisfactory nozzle spray and accurate fuel regulation. In order to improve modulation performance of the electric fuel pump with all conditions accessible, a complete mathematical model of the pump is built and the hybrid control strategy within the scope of whole operation is proposed, considering the measured parameter of fuel flow as feedback. The control strategy consists of a feed-forward compensation based on differential pressure and backstepping non-singular fast terminal sliding mode control with extend state observer. Results show that the hybrid control strategy can meet the requirements of fuel flow regulation for aeroengines including accuracy of wide range flow and quick response ability. Additionally, the effectiveness of redundancy design is shown, which contributes to its reliability as an airborne component.
