Robustness Analysis and Realization of Parameters Adaptive Control for Vector-Controlled Induction Motor

摘要:
采用矢量控制的感應電動機,其控制性能與它激直流電機類似,用這種控制方法,電機的轉矩電流分量和磁通電流分量可實現解耦控制。本文討論矢量控制系統的魯棒性。針對前饋矢量控制系統中由于電機參數與速度檢測小誤差造成磁場定向錯誤,提出了一種新的自適應校正策略,該策略采用PRBS在線辨識技術,算法簡單,不需要額外的傳感器。最后給出了系統實現及實驗結果。
Abstract:Some incorrectness of field orientation system made by motorparameter and speed detecting errors are presented in vcctor control system. The robustness of a field-forward vector control system is studied. A new adaptive correction strategy used PRBS on-line identification technique is proposed. This method is simnle and doesn't need extra sensors.
