本論文以硬體描述語言VHDL實現感應馬達向量控制之FPGA硬體數位電路設計，並以DSP晶片產生控制命令與參數存取，完成實驗與驗證。論文中使用Altera Quartus II發展硬體合成電路，並藉由模擬分析其時序功能。設計方法採由上而下(top-down)之方式，將向量控制法則分成數個獨立模組，以模組為單位設計與驗證電路，再逐一組合成完整之向量控制架構。
實驗方面，以FPGA進行向量控制之數位電路設計，搭配DSP系統完成馬達回授與檢測的功能，形成DSP-FPGA整合式數位控制系統。DSP系統主要負責參數與暫存器寫入與讀取、光編碼器解碼、電流回授訊號、以及PWM訊號之產生。FPGA系統負責實現向量控制演算法與介面電路之設計。論文中所進行之實驗以此為平台，實驗初期先以DSP軟體程式為基礎，次將向量控制各模組，逐一以硬體取代，驗證其功能正確性，並由內部擴展至外部，最後以FPGA實現整個感應馬達向量控制運算法則。
本論文成功的驗證了向量控制在感應馬達驅動IC實現上之可行性，也顯示未來馬達驅動技術在IC設計上，深具潛力與發展性。

This thesis uses the VHDL to design the FPGA-based hardware digital circuits for realizing the vector control laws for an induction motor. In order for experiments and verification, a DSP chip is utilized for control command generation and parameters read/write. The design approach is top-down, in which the vector control laws are divided into several modules; the circuit for each module is developed and verified. They are combined together to form the complete vector control structure.
In setting up the experimental system, a DSP-FPGA integrated digital control system is developed, in which the FPGA is used for implementing the digital circuits for vector control and the DSP is used for feedback signal processing, sensing, and measurement. The DSP is responsible for parameter and register read/write, optical encoder and current feedback signal processing, and PWM signal generation. The FPGA is to realize the vector control algorithms and interfacing circuits. Based on this integrated system platform, the experiments are initially based on soft-based DSP programs only. Then, starting from the innermost control loop and working outward, the vector control modules are gradually replaced by the FPGA-based digital circuits. In the final step, the complete vector control algorithms are realized by the FPGA.
This thesis has demonstrated the feasibility of implementing a vector control IC for induction motors. It also shows the future potential in developing control ICs for motor drivers.
