摘要: | 本論文主旨為三相內藏式永磁同步電動機控制策略之設計及實現,此電動機將永久磁鐵埋入於轉子內部,具有強健的機械結構,適合應用於高速運轉及高性能電動機車驅動系統中,文中有介紹兩種電動機操作區域:定轉矩區及定功率區,於定轉矩區採用每安培最大轉矩控制,選擇此控制有最小的電流,且產生最大轉矩及最小的銅損,當反電動勢高於三相變頻器直流限制電壓,需藉由反向d軸電流弱化磁通鏈,因此於定功率區採用弱磁控制,延伸轉速操作範圍。在控制器設計上,本論文採用模糊控制器取代傳統的比例積分控制器,藉由調整模糊控制器之參數區間, 使得永磁同步電動機有較好的響應。最後,於軟體MATLAB/SIMULINK 上建立不同控制策略應用在電動機驅動系統中,並使用德州儀器TMS320F28069M 數位信號處理器實現三相內藏式永磁同步電動機驅動系統實驗,實驗結果顯示上述控制策略具有可行性。 This thesis aims to design and implement the control strategies for three phase interior permanent magnet synchronous motor (IPMSM). IPMSM has a robust mechanical structure for permanent magnets inside the rotor, which can be applied to the electrical motorcycle drive system of high speed operation and high performance. The two motor operational regions will be mentioned in the thesis, including the constant torque region and constant power region. The Maximum torque per ampere (MTPA) control strategy is adopted to generate the maximum torque and minimize the copper losses in the constant torque region, which is a better choice for the minimum current. When the back electromotive force (back EMF) is higher than three phase inverter DC limit voltage, the flux linkage needs to be weakened by demagnetizing the effect of the d-axis current. Therefore, the flux weakening control strategy is adopted to extend the speed operational region of IPMSM in the constant power region. In terms of controller design, the fuzzy controller is adopted to replace the conventional proportional integral (PI) controller in this thesis. By tuning the interval parameters of the fuzzy controller, IPMSM can receive better reviews. Finally, the different types of the control strategies established in the MATLAB/SIMULINK software are applied to IPMSM drive system. Also, Texas Instruments TMS320F28069M digital signal processor is used to implement the experiments of three phase interior permanent magnet synchronous motor drive system. The results show the feasibility of the aforementioned control strategies. |
