Speed Synchronized Control of Dual Motors System Using Fuzzy Logic

This paper proposes a cross-coupling control based on fuzzy controller for dual motors. To guarantee the requirement for high accuracy in speed synchronization, the system synchronous error feedforward control and fuzzy logic based cross-coupling control algorithm are applied to dual motor to counteract the influence of different motor parameters. The improved cross coupling control dynamically adjusts the coupled feedback coefficient through the fuzzy controller, which significantly improves the synchronization performance during the startup phase, and the system can maintain good synchronization under the unbalanced disturbance. The simulation results show that the improved control method is effective and yield superior performance over traditional cross-coupling control.
