本論文主要建立感應馬達向量控制系統,因此首先對感應馬達的模型進行分析及推導,討論純量控制法(Scalar Control)與向量控制法(Vector Control)的差異,並且使用向量控制來建立控制系統,包含扭力控制、速度控制;接著,針對向量控制所需的參數進行參數系統鑑別,分別是直流、堵轉-單相、無載試驗,最後再介紹自行設計並建立的驅動電路。在實作方面上,我們使用德州儀器所生產的TMS320F28335數位訊號處理器作為運動控制卡,進行感應馬達向量控制實驗,利用自行設計的驅動電路,透過自行編寫的韌體驅動電力模組,驗證感應馬達向量控制理論可經由DSP控制卡及驅動電路所驅動。
This thesis describes how I to creat a vector control system for an induction motor. First analyzed the model of the induction motor, and then research the viability of two control theories, scalar control and vector control. It was decided upon to use vector control. I also researched vector control theory of torque control and speed control. Then I identified the system parameters which are required in order to implement vector control. The experiments used were DC, Stall-signal phase, and no load. Finally I introduced the driver, which was designed by my department. In the implementation I used TMS320- 28335 digital signal processor (DSP) microcontroller, designed by Texas Instruments and the DSP control card which was produced by C.C.U. Auto-Control Lab. I then conducted the induction motor experiments on the driver and firmware in order to verify the feasibility of an induction motor vector control systems via a driver and DSP is acceptable.
