摘要

本文主要目的為發展永磁同步馬達變頻驅動器之技術，首先分析馬達的數學模型，並基於脈波寬度調變技術發展弱磁控制技術，以充分利用DC-Bus電壓與變頻器可輸出之電流，達到最大轉矩與功率。
本文利用德州儀器公司所生產的數位訊號處理器TMS320F28035為控制平台，驗證具有弱磁控制之內崁式永磁同步馬達變頻驅動器的實作及設計分析的正確性。所使用的內崁式永磁同步馬達詳細規格為額定功率750 W、額定轉矩2.4 Nt-m、額定轉速3000 rpm、最高轉速4500 rpm、極數4極、額定電壓194V。由實驗結果可知此系統之動態響應和暫態響應皆符合規格要求，驗證所研製之永磁同步馬達變頻驅動器的可行性。

This objective of this thesis is to develop the techniques for inverter-controlled permanent magnet synchronous motor driver. First, the mathematical model of IPMSM is analyzed. Vector-controlled IPMSM drives with proposed flux weakening control technique to achieve fully utilization of DC-bus voltage is implemented based on pulse-width modulation technique.
In the thesis, Texas Instruments produced Digital Signal Processors (DSP) TMS320F28035 is used as the control platform. It is confirmed that flux weakening control will successfully accomplish the developed technique required for the design and implementation of IPMSM drives. The used interior permanent magnet synchronous motor is with specifications of rated power 750W, rated speed 3000 rpm, maximum speed 4500 rpm, number. of poles 4, rated voltage 194V, rated current 4A. Experimental results show satisfied results for both dynamic response and steady state response. These results confirm the design and implementation of the vector-controlled IPMSM drives.
