A group of independent rolling motley is an important feature of the electronic shaft driving printing machine, and the multi-motor synchronization in the control system is the key. This work aimed to study the multi-motor synchronous control strategy to ensure the quality of printing. The master-slave structure and parallel structure were compared. Modeling and simulation were conducted for the two different structures using Matlab. The parallel structure strategy for electronic shaft driving synchronous control was determined and improved. Velocity compensator based on the fuzzy PI algorithm was proposed to replace the synchronous control structure with coupling coefficient of K1 and K2. This strategy improved the synchronous tracking performance and anti-interference ability of the double-motor synchronous control system, and enhanced the synchronous coordination of multi-motor electronic shaft driving gravure printing machine.
