本論文主要是以DSP為基礎,結合Matlab Simulink輔助,於感應馬達中建立向量控制系統,因此首先對感應馬達模型和向量控制進行介紹與分析,並針對感應馬達原理及轉子時間常數進行理論推導,將得出理論建立Matlab Simulink模擬。實驗方面,我們使用德州儀器公司所生產之TMS320F28335數位訊號處理器作為訊號控制卡進行向量控制,並經由訊號控制卡量測與計算出實驗數據,接著進行轉子時間常數理論推導,結合Matlab Simulink,將推導模型建立、以及設計轉子時間常數估測流程,省去傳統透過儀器量測馬達定轉子電阻參數後計算轉子時間常數的流程,能夠在速度迴路下進行時驗後估測出轉子時間常數,最後結合模擬與實驗之結果進行討論,以及當馬達參數改變時,對其轉子時間常數估測與加速度之影響提出說明。 This thesis is to develop a DSP-based vector control system of the induction motor,and then we analyze the (IM) MATLAB Simulink simulation Since the main structure of this thesis is induction motor(IM), And theoretical deduction with Induction motor principle and rotor time constant. We can get the Matlab Simulink model.By the experimental aspects, we use TMS320F28335 digital signal processor motion control card for vector control, And through the signal control card measurement and calculation of experimental data, then we find theoretical derivation of rotor time constant. In the end, we combined with Matlab Simulink, the derivation model is established. As well as the design of the rotor time constant estimation process. When we design the rotor time constant estimation flow, we can eliminates the process of calculating the motor parameters. The rotor time constant can be estimated after the time loop is executed in the speed loop. Finally, the results of simulation and experiment are discussed, and when the motor parameters change, describe the rotor time constant estimation and the effect of acceleration
