Research on a Multi-Motor Coordinated Control Strategy Based on Fuzzy Ring Coupling Control

Targeting the problem of multi-motors coordinated control on offshore jack-up platforms, fuzzy control technology is introduced into the ring coupling synchronous control structure, with a new multi-motor speed tracking and synchronization control method is proposed. Every motor is couple with adjacent electric machines to form a Multiple motors ring network structure to ensure speed tracking performance. The fuzzy controller is used to adjust the parameters of the synchronization error compensator of this strategy. Take the synchronization error and the change of the synchronization error of two neighboring motors as the entered of the fuzzy controller, and the output is compensated to the first motor of the adjacent motor. On the four-motor synchronous control system, the performance comparison with traditional cross coupled control and the effectiveness of the proposed control-strategy are studied is experimentally verified by the simulations. Four motor synchronous speed established experimental platform system, and show the validity by the Fuzzy control loop coupling experiment proposed structure.
