本文論文利用高頻電流注入法以及PI-MRI控制器，估測出永磁同步馬達的電氣參數。並運用電機參數估測的方法，可以應用在永磁同步馬達的三種方法1)極性估測:準確的極性位置，可結合一般的無感測角度估測技術，用於啟動方法上。2)鐵損電阻的估測:獲得鐵損電阻依頻率的變化量，有助於研發更有效率的演算法。3)高頻注入轉子位置估測器參數的適應性調整:線上估測馬達電氣參數的變動，即時補償估測器的參數，以獲得更好的估測性能。

This thesis utilizes the high-frequency current injection method and the PI-MRI control topology to estimate the electrical parameters of the permanent magnetic synchronous motor (PMSM). Through the motor parameter estimations under various operating conditions, three methods and possible applications concerning PMSM drive and control are developed. 1) Magnetic polarity detection method: The accurate detection of the magnetic polarity combined with the conventional rotor position estimation method enables the start-up of the sensorless PMSM at standstill. 2) Core-loss resistance estimation method: The identification of the frequency-dependent core-loss resistance helps develop a loss minimization control algorithm for PMSM. 3) On-line tuning of high-frequency-injection estimator of the rotor position of the PMSM : On-line estimations of the electrical parameters of the PMSM enable the tuning of the estimator for better performance.
