AI Technical Summary
Existing aviation electric fuel pump control devices suffer from sensor accuracy degradation under high temperature and vibration environments, resulting in low control precision, phase lag causing motor step loss, complex control strategies, and large parameter errors, all of which affect the reliability and accuracy of the electric fuel pump.
By employing a dual extended Kalman filter estimator and a vector controller, combined with a phase lag compensator, sensorless control is achieved by estimating motor parameters and rotor position. Real-time compensation is performed using a DSP, thereby improving control accuracy and reliability.
The control accuracy and reliability of the electric fuel pump are improved under high temperature and vibration conditions, avoiding motor speed fluctuations and instability caused by sensor failure, and ensuring accurate estimation of motor speed and flow control.
