矢量控制系统动态电压解耦与调节器整定

摘要

A dynamic decoupling strategy is adopted to decouple the stator voltage.This method improves the robustness 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.%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.
