【摘要】:在當(dāng)今能源短缺的情況下,電動車的發(fā)展變的尤為重要。車用電機控制器是電動汽車的最關(guān)鍵的部分之一,受到了國內(nèi)外學(xué)者的高度重視,近些年來發(fā)展也非常迅速。永磁同步電動機因有高效率、高功率密度、調(diào)速性能好等優(yōu)點,被用作電動汽車驅(qū)動電機,對其控制方法的研究很有意義。IGBT是永磁同步電機控制器的核心部件,然而IGBT驅(qū)動效果的好壞對電機驅(qū)動的安全性和可靠性有非常大影響,所以對IGBT驅(qū)動技術(shù)的研究很意義。 本文首先對永磁同步電機建立了數(shù)學(xué)模型,并介紹了矢量控制方法和空間矢量脈寬調(diào)制(SVPWM)技術(shù),并在MATLAB/Simulink環(huán)境下對SVPWM進行仿真。本論文以TMS320F2812為主控芯片,在該控制器中還包括了電源電路、信號檢測電路和保護電路等,在論文中對每一硬件部分做了詳細的介紹,分析了每個電路的功能和作用。同時介紹了軟件流程,重點介紹了中斷部分的軟件流程,并對位置信號處理和校正做了詳細說明。在硬件電路中著重分析了驅(qū)動電路部分。對IGBT的選型做了詳細的介紹,并對驅(qū)動電路的要求做了進一步的說明。在本論文中驅(qū)動芯片選用的是HCPL-316J,而IGBT開通和關(guān)斷所需的+15V和-5V電壓,由所設(shè)計的開關(guān)電源電路提供。同時對IGBT的通態(tài)損耗和開關(guān)損耗做了分析,并對引起損耗的參數(shù)做了分析說明。最后為了驗證控制器的特性,在實驗臺架上做了大量的實驗,,驗證了控制器的整體方案的設(shè)計。通過實驗證明該控制器能夠在電動車中可靠運行。
[Abstract]:Under the circumstance of energy shortage, the development of electric vehicle becomes more and more important. Motor controller is one of the most important parts of electric vehicle, and has been attached great importance by scholars at home and abroad. In recent years, permanent magnet synchronous motor (PMSM) has been used as a driving motor for electric vehicles because of its advantages of high efficiency, high power density and good speed regulation performance. The research on the control method is very significant. IGBT is the core component of PMSM controller. However, the effect of IGBT driving has a great impact on the safety and reliability of the motor drive, so it is very important to study the IGBT driving technology. In this paper, the mathematical model of permanent magnet synchronous motor is established, and the vector control method and space vector pulse width modulation (SVPWM) technology are introduced, and the SVPWM is simulated under the MATLAB/Simulink environment. In this paper, TMS320F2812 is used as the main control chip. The controller also includes power supply circuit, signal detection circuit and protection circuit. In this paper, each hardware part is introduced in detail, the function and function of each circuit are analyzed, and the software flow is introduced. The software flow of interrupt part is introduced emphatically, and the position signal processing and correction are explained in detail. The driving circuit is emphatically analyzed in hardware circuit. The selection of IGBT is introduced in detail. In this paper, HCPL-316J is selected as the driver chip, and the 15V and -5V voltages needed for IGBT turn-on and turn-off are introduced. At the same time, the on-state loss and switching loss of IGBT are analyzed, and the parameters that cause the loss are analyzed. Finally, in order to verify the characteristics of the controller, a large number of experiments have been done on the experimental bench. The overall design of the controller is verified, and it is proved by experiments that the controller can run reliably in electric vehicles.
