Dual-motor Cross-coupling Control Strategy Based on Fuzzy Feedback Gain
The mathematical model of dual permanent magnet synchronous motors is established.Aiming at the problem of synchronous performance degradation during system startup and unbalanced load conditions in traditional cross-coupled control,a fuzzy feedback gain controller is designed to adjust the feedback gain based on the synchronous error and its rate change in the dual motor system,thereby improving the synchronous performance.The simulation analysis in MATLAB/Simulink verifies that the proposed improved cross-coupled control based on fuzzy feedback gain improves the system's synchronous performance during startup and under unbalanced disturbances.
