本文旨在研製一套全數位化矩陣轉換器驅動永磁同步電動機系統。文中，首先說明永磁同步電動機的結構、特性及數學模式，其次，提出新型的矩陣轉換器控制策略，以期延長矩陣轉換器在電源中斷時，瞬停再啟動的時間。本文以TMS-320-LF-2407A之數位訊號處理器與EPM-570-GT-100-C4之高複雜度可程式化邏輯元件，達成電流及速度控制，使得硬體電路大為簡化。相關的分析均以實測加以驗證，實測結果說明本文所提出的相關法則確實可行，且具有良好的暫態及加載性能，並可延長瞬停再啟動的時間。

This thesis investigates the design and implementation of a full-digital matrix converter for PMSM drive systems. First, the structure, characteristics, and mathematical model of the permanent magnet synchronous motor are discussed. Next, a new control strategy is proposed to extend the ride-through time when the power of the matrix converter is interrupted. The implemented system uses a digital signal processor, TMS-320-LF-2407A, and a CPLD, EPM-570-GT-100-C4, to achieve the current and speed control. As a result, the hardware is simple. Experimental results validate the theoretical analysis. In addition, satisfactory transient responses, load disturbance responses, and extended ride-through interval are obtained.
