摘　　要：建立双永磁同步电机的数学模型,针对传统交叉耦合控制存在的系统起动阶段和受不平衡负载情况下同步性能下降问题,从反馈增益的角度出发,通过设计模糊反馈增益控制器,使得系统能够根据双电机系统的同步误差及其变化率调整反馈增益以达到提升同步性能的效果,通过MATLAB/Simulink仿真建模分析,验证所提出的基于模糊反馈增益的改进交叉耦合控制策略改善了系统在起动过程以及不平衡扰动情况下的同步性能。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 crosscoupled 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.
