    Abstract: 本篇論文主要是透過調節交軸(q 軸)電流控制器的比例積分器增益值來達成永磁式同步電動機電氣參數的估測,並與傳統參數量測方法的結果做比較。首先,探討永磁式同步電動機的數學模型。發現在旋轉座標系中各參數間為非耦合,有利於控制架構的簡化。然後根據此數學模型,可以推導出本論文的參數估測方法之理論,同時詳細說明其實驗步驟。接著,介紹驅動器硬體架構。依功能性不同做模組化設計,共區分成載板、數位訊號處理器模組、電源模組、編碼器模組。其中數位訊號處理器模組將DSP2407 及CPLD95288 兩種晶片整合為一個完整的功能模組。 最後,將參數的估測結果與傳統方法的量測結果做比較與討論,以驗證其正確性。 The focus of this thesis is to achieve the purpose of estimating parameters of SPMSM by tuning the proportion-integral(P-I) gain of the current controller,and we compare the results with traditional methods. First, we researched on mathematical model of PMSM, and found that the variables are not coupling in rotating coordinate state, and control structure become simpler. Then, We derive the formula for estimating parameters according to the mathematical model of PMSM and specifiy the processes of the experiment. Second, we briefly state the hardware structure of motor driver. Each part of the driver is designed according to its function separately. There are four modules that construct the motor driver. They are carrier board, DSP module, power module and encoder module. Finally, we verify the parameters by comparing the results of the experiment with traditional methods.
