本文探討空間向量調變補償法的內藏式永磁同步電動機驅動系統的轉軸角/速度估測以及預測型速度控制器的設計。文中經由計算三相定子的電流斜率，再由電流斜率估測轉軸角度及轉軸速度。由於電動機在靜止或低轉速時，空間向量脈波寬度調變的主動電壓向量導通區間甚短，無法準確地計算電流斜率，達成轉軸角度估測。故本文使用三段式空間向量脈波寬度延伸及補償的方式，增加主動電壓向量的導通時間，避免產生過大的電流諧波量。實驗結果說明本文所提方法，可以改善傳統磁滯電流控制器所造成電流諧波量過高的缺點。
為了增進電動機的暫態響應、追蹤能力及加載性能，文中使用預測型速度控制器應用於無轉軸偵測元件的驅動系統。利用性能指標函數，推導出預測型的最佳控制量。

This thesis investigates the rotor position/speed estimation using space-vector modulation compensation method and the predictive speed-loop controller design for interior permanent magnet synchronous motor drive systems. By computing the three-phase current slopes, the rotor position and speed of the motor can be estimated. The duty cycles of the active vectors could be too small; as a result, it is impossible to obtain the current-slopes of the active vectors when the motor is operated at standstill or low-speed operating region. An extension and compensation of three-level space-vector pulse width modulation method is proposed here. By using this method, the duty cycle of the active voltage vector is increased and the current harmonics are not obviously increased. The experimental results show that the current-slope computing method can be employed to estimate the rotor position/speed to improve the performance of the traditional hysteresis current control method, which causes too much current harmonics.
To improve the transient response, tracking ability and load disturbance rejection capability, the predictive speed-loop controller is used for the sensorless IPMSM drive systems. An predictive optimal control input is derived by using the performance index for the whole drive system.
A digital signal processor, TMS-320F-2808 is used as a control center to execute the control and estimation algorithms. Experimental results show the correctness and feasibility of the proposed methods.
