摘　　要：采用动态解耦方法对定子电压进行解耦,提高解耦控制器对电机参数估计误差的鲁棒性,充分消除励磁电流内环与转矩电流内环之间的耦合。采用调节器常规工程设计方法,提出了一套异步电动机无速度传感器矢量控制系统双闭环PI调节器整定方法,实验结果验证了其良好的性能。A dynamic decoupling strategy is adopted to decouple the stator voltage.This method improves the robust- ness of motor parameter estimation error occurred by the controllers, and eliminates completely the coupling between field current and torque current.A conventional engineering regulator design is presented,and a design method based on double closed-loop PI regulator for speed sensorless vector control system is proposed.The experimental results demonstrate its good performance.
