Research on synchronous control method of dual servo electric cylinder based on PLC

In this research work, Three non coupled dual servo electric cylinder synchronous motion control schemes based on PLC control have been designed, which are parallel synchronous control, master-slave synchronous control, and virtual axis synchronous control. A dual servo motor synchronous control experimental platform was built, with the core controller being PLC. Three synchronous control schemes were tested under the same load, different loads, and variable loads. Among them, the synchronization performance of dual servo motors under virtual axis synchronization control is better than the other two methods. Then, a dual servo electric cylinder synchronization control experiment was conducted on the virtual axis synchronization control method. The results showed that under this method, the position difference between the two servo electric cylinders was small, and there was no cumulative deviation, indicating good synchronization.
