摘 要
本論文的研究目的是建立一套完整的直流無刷馬達驅動器電腦模擬系統，涵蓋馬達數學模型、脈波寬調變(PWM)策略、無量測器速度控制等。本論文首先針對永磁式直流無刷馬達進行數學模式的推演，再以MATLAB-SIMULINK建立馬達的模擬架構。在輸入設定的三相端電壓於馬達模擬模組，可獲得並分析馬達旋轉所造成的各種物理現象，如定子三相電壓、反電動勢、電流、電壓等。接著本論文探討如何藉所建立的電腦模擬程式去檢測反電動勢以獲得轉子位置的估測資訊來進行速度控制。最後本論文將模擬的結果與利用DSP-FPGA混合系統獲得的實驗結果分別做分析與比較。比較結果顯示本論文所提出的模擬系統可以配合實體系統之開發，提供有效的電腦輔助設計工具。
Abstract
The prupose of this thesis is to establish a complete computer simulation system for a dc brushless motor drive, which includes the motor model, pulse-width modulation (PWM) strategy, and sensorless speed control. The thesis first derives the mathematical model for the permanent magnet dc brushless motor and then uses MATLAB Simulink to establish the motor simulatior programs. Applying the designated three-phase voltage commands to the motor simulator modules, various physical phenomena, such as three-phase stator voltages, back electromagnetic forces (BEMF), and currents can be obtained and analyzed. The thesis further investigates the establishment of the simulation programs to detect the back EMFs and to obtain the estimated rotor position for speed control. Lastly, the thesis gives a comparison of the simulation results with the experimental results obtained from a DSP-FPGA system. The comparison results show that the proposed simulation system can accommodate the development of the hardware system and provide an effective computer-aided design tool.
