AI Technical Summary
Existing technologies cannot effectively control the periodic scanning motion of the moving mirror in a moving mirror scanning system, resulting in a large periodic error of the moving mirror.
A pre-set active disturbance rejection control system is adopted. By inserting a repetitive controller, combined with a linear extended state observer and a state error feedback control law, the motor parameters of the voice coil motor and the target voltage signal are determined to correct the difference between the actual angular velocity and the target angular velocity of the moving mirror during the periodic scanning motion.
It improves the tracking accuracy and anti-interference capability of the moving mirror scanning system, ensures that the difference between the actual angular velocity of the moving mirror and the target angular velocity is maintained within the preset threshold, and reduces periodic errors.
