Design and development of photoelectric pod permanent magnet torque motor control system
Aiming at the problems of target tracking lag and poor stability in the current optoelectronic pod control system,a three-closed-loop motor control method based on position feedforward is proposed.According to the control performance parameters and indicators of a photoelectric pod,a motor drive controller using STM32 as control core is designed,and the current,speed and displacement response curves during operation are given,and the waveforms under the traditional control system are analyzed and compared.Considering that the position sensor is damaged in harsh environment,a sensorless control algorithm based on extended Kalman filtering (EKF)is proposed.The results show that the control strategy improves the target tracking performance during the motor operation and effectively suppresses motor torque pulsation.The designed controller is reliable in design and stable in performance.
