“…However, the electric fuel system eliminates the AGB, metering unit, bypass valves, and air-cooled oil cooler, making it possible to reduce weight and improve oil heat management and system efficiency [9]. These goals are achieved by utilizing a motor-driven fuel pump, fuel pressurizing valve and pressure sensors.…”

More electric engines (MEEs) and more electric aircraft (MEA) are mainly implemented to address the global warming issue and make engines more fuel efficient. Developing technology has made them applicable. This paper presents a detailed introduction to the MEE for civil aircraft, including its architecture, characteristics and performance, as well as the potential benefits of fuel consumption and emissions reduction. It is obvious that the adoption of electric components, such as active magnet bearings, electric starters and generators and electric fuel pumps, is beneficial. It is especially

“…Electric motor drives are capable of converting electrical power to drive actuators, pumps and compressors at variable speed [15]. Electric motor‐driven fuel pumps provide variable speed solutions to control the fuel flow rate which matches the actual demand [16]. EMDPs can provide variable speed to control the output flow rate of hydraulic pump through the order of flight control computer.…”

“…Through the study of different motor drive control strategies, reference 16 proposed to replace the current control method of the electric driven centrifugal pump with an improved open and closed loop strategy, which could reduce the overshoot of the fuel flow and the fluctuation of the fuel pressure. As a key component of the more electric actuator, 17 the performance of the motor drive fuel pump fuel supply system inevitably affects the working state of the engine. Especially for the afterburner fuel system, it adopts the method of zoned fuel supply to improve the combustion efficiency.…”

More electric engine (MEE) with electric pump metering fuel has the problem of unstable engine control due to the dead-zone characteristics of afterburner fuel actuator. On the basis of conventional μ modified adaptive control method, a compound modified adaptive control (CMAC) system based on neural network inverse model is proposed in this study. At first, the afterburner fuel actuator model of MEE is established through Simulink/AMESim co-simulation to study its fuel supply characteristics and reveal the reasons for dead-zone characteristics of the actuator. Subsequently, an integrated model of afterburner fuel actuator/MEE is established to investigate the effect of dead-zone characteristics on engine performance. Finally, the CMAC system for afterburner fuel flow closed-loop control based on neural network inverse model and improved μ modified adaptive control method is designed. The simulation results show that the dead-zone characteristics of afterburner fuel actuator can cause engine shaking and unstable operation. The engine thrust has a continuous fluctuation with amplitude of about 0.2%. The proposed CMAC system can effectively avoid the dead-zone interval of actuator and achieve stable transition of the engine state in the entire operating range of the afterburner fuel actuator. Thus, the stability of the control system can be significantly improved. Meanwhile, the improved μ modified adaptive control algorithm in the CMAC system has better dynamic characteristics when compared with the conventional μ modified adaptive control algorithm.
