摘要: | 本文研究主軸為電動載具系統內逆變器與電動機之建模,目標使產品在開發前擁有精準的模型,以縮短開發週期與提高效率。在逆變器方面,本文使用矽基金氧半場效電晶體(Si-Metal-Oxide-Semiconductor Field-Effect Transistor, Si-MOSFET)作為功率元件,以Enz-Krummenacher-Vittoz (EKV)模型作為SPICE建模基底,並經由改良使功率元件不管是靜態或動態特性都能更加精準,也同時提高模型之強健性,對於不同操作電壓與溫度模型皆能精準輸出。在電動機方面,本文利用Ansys Motor-CAD對市售4 kW內藏式永磁同步馬達進行建模,並且藉由調整設計參數來優化此永磁馬達,提升其輸出扭力與降低轉矩漣波,同時也將田口法實驗概念套用至設計上,使馬達達到最佳化設計。而為了驗證優化模型,本文也針對驅動控制做研究,先以MATLAB/Simulink軟體結合空間向量脈寬調變與向量控制技術模擬電動載具驅動系統,分析不同控制策略對永磁馬達之響應,再使用數位信號處理器TMS320F28069M與三相逆變器等硬體設備開發驅動控制系統,驗證優化馬達的動力輸出是否符合設計目標。 This thesis studies the modeling of the inverter and motor for the electric vehicle system. In order to make the product have an accurate model before development, so as to shorten the development cycle and improve the efficiency. In terms of inverters, this thesis uses silicon-based Metal-Oxide-Semiconductor Field-Effect Transistor (Si-MOSFET) as power devices, and Enz-Krummenacher-Vittoz (EKV) model as the SPICE modeling substrate. Through the improvement, the power devices can be more accurate in both static and dynamic characteristics. At the same time, the robustness of the model is improved, and the model can be accurately output for different operating voltages and temperatures. In terms of electric motors, this thesis uses Ansys Motor-CAD to model a commercially 4 kW Interior Permanent Magnet Synchronous Motor (IPMSM), and optimizes it by adjusting the design parameters to increase its output torque and reduce torque ripple. At the same time, the experimental concept of Taguchi method is applied to the design to optimize the motor design. In order to verify the optimized model, this thesis also studies the drive control. The electric vehicle drive system is simulated by MATLAB/Simulink software combined with SVPWM and vector control technology, and the response of different control strategies to the IPMSM is analyzed. Then use the digital signal processor TMS320F28069M and hardware equipment such as three-phase inverters to develop the drive control system to verify whether the power output of the optimized motor meets the design goals. |
