【摘要】：在當(dāng)今能源短缺的情況下，電動(dòng)車(chē)的發(fā)展變的尤為重要。車(chē)用電機(jī)控制器是電動(dòng)汽車(chē)的最關(guān)鍵的部分之一，受到了國(guó)內(nèi)外學(xué)者的高度重視，近些年來(lái)發(fā)展也非常迅速。永磁同步電動(dòng)機(jī)因有高效率、高功率密度、調(diào)速性能好等優(yōu)點(diǎn)，被用作電動(dòng)汽車(chē)驅(qū)動(dòng)電機(jī)，對(duì)其控制方法的研究很有意義。IGBT是永磁同步電機(jī)控制器的核心部件，然而IGBT驅(qū)動(dòng)效果的好壞對(duì)電機(jī)驅(qū)動(dòng)的安全性和可靠性有非常大影響，所以對(duì)IGBT驅(qū)動(dòng)技術(shù)的研究很意義。 本文首先對(duì)永磁同步電機(jī)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(duì)SVPWM進(jìn)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(hào)檢測(cè)電路和保護(hù)電路等，在論文中對(duì)每一硬件部分做了詳細(xì)的介紹，分析了每個(gè)電路的功能和作用。同時(shí)介紹了軟件流程，重點(diǎn)介紹了中斷部分的軟件流程，并對(duì)位置信號(hào)處理和校正做了詳細(xì)說(shuō)明。在硬件電路中著重分析了驅(qū)動(dòng)電路部分。對(duì)IGBT的選型做了詳細(xì)的介紹，并對(duì)驅(qū)動(dòng)電路的要求做了進(jìn)一步的說(shuō)明。在本論文中驅(qū)動(dòng)芯片選用的是HCPL-316J，而IGBT開(kāi)通和關(guān)斷所需的+15V和-5V電壓，由所設(shè)計(jì)的開(kāi)關(guān)電源電路提供。同時(shí)對(duì)IGBT的通態(tài)損耗和開(kāi)關(guān)損耗做了分析，并對(duì)引起損耗的參數(shù)做了分析說(shuō)明。最后為了驗(yàn)證控制器的特性，在實(shí)驗(yàn)臺(tái)架上做了大量的實(shí)驗(yàn)，，驗(yàn)證了控制器的整體方案的設(shè)計(jì)。通過(guò)實(shí)驗(yàn)證明該控制器能夠在電動(dòng)車(chē)中可靠運(yùn)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.
