Abstract
The current traditional motor cross-coupling synchronous control method is designed by adaptive control algorithm of neural network observer to achieve synchronous control of multi-servo motors, which leads to poor control effect due to the lack of analysis of the friction force generated in the cross-coupling process. In this regard, a friction compensation-based synchronous control method for multi-servo motor cross-coupling is proposed. The Stribeck friction model is selected as the object of identification and compensation, the virtual spindle synchronization control strategy is adopted as the main strategy, and the fuzzy PID compensation controller is designed. In the experiment, the control accuracy of the proposed control method is verified, and the analysis of the experimental results shows that the synchronization error of the motor is small and has high synchronization control accuracy when the proposed control method is used to cross-couple the multi-servo motor.
