Research on Synchronous Control Method of Dual Motor Based on ADRC Speed Compensation

To solve the problem of inconsistent speed response time of dual motors under load disturbance, a synchronous control method of dual motors based on the combination of virtual spindle and fuzzy-LADRC (VS-FLADRC) is proposed in this paper. In this method, the speed error between two motors is corrected and compensated by the fuzzy linear active disturbance rejection speed compensator, which is input into the virtual spindle together with the target speed to achieve accurate control, so as to solve the problems of the double motor synchronous control system in practical application, such as hysteresis and poor load characteristics. The experimental results show that VS-FLADRC can significantly improve the speed response ability and synchronization control precision of the synchronous control system under load disturbance, also has strong anti-interference ability and robustness, which effectively realizes the precision collaborative control of dual motors.
