Abstract
Aiming at the problem of poor position synchronization accuracy in the process of multi-motor lifting, a multi-motor lifting synchronization control method based on digital twin is proposed. Firstly, a four-column multi-motor synchronous lifting digital twin of heavy-duty stacker with high stability and security is established to realize virtual and real time synchronous mapping between physical entity and digital twin. Then, an improved Seagull optimization algorithm (ISOA) is proposed to optimize the quantization factor and scale factor of fuzzy PID controller to realize the adaptive stable synchronous control of multi-motor lifting mechanism. Finally, through simulation analysis and engineering project practice, the reliability of the design of four-column multi-motor lifting heavy-duty stacker and the effectiveness of the multi-motor synchronous control method based on digital twin are proved.
