Strategic Analysis and Experimental Research on Synchronization Control of Dual-Motor in Crane

In order to ensure work safety, large cranes generally use two motors together to upgrade the load, so often there is a synchronization error, control accuracy is affected. To address this issue, the paper crane hydraulic lifting system to study proposed control strategy based on fuzzy PID's. The results show that the method used to effectively reduce the synchronization error between the two motors to improve the control precision crane, a certain reference value.
