【摘要】：隨著電力電子器件和永磁材料的不斷發(fā)展和進步，出現(xiàn)了無刷直流電機，它用電子換向裝置取代了普通直流電動機的機械換向裝置，消除了普通直流電機在換向過程中存在的換向火花，電刷磨損，維護量大，電磁干擾等問題，延長了電機的壽命。使用適當(dāng)?shù)目刂撇呗�，能夠使無刷直流電機擁有和普通直流電機的一樣優(yōu)點，例如調(diào)速范圍大、運行穩(wěn)定、轉(zhuǎn)矩大、功率密度高等。所以無刷直流電機控制系統(tǒng)的研究有著深遠的意義。 首先，論文介紹了研究無刷直流電機的背景及意義，說明了無刷直流電機的優(yōu)勢、應(yīng)用領(lǐng)域等，推導(dǎo)了無刷直流電機的動態(tài)數(shù)學(xué)模型，描述了無刷直流電機的工作原理，搭建了無刷直流電機控制仿真模塊。對矢量控制理論進行了研究，深入研究了坐標(biāo)變換和SVPWM控制，并推導(dǎo)了有關(guān)id=0矢量控制的數(shù)學(xué)方程式，設(shè)計了基于勵磁電流分量為零的無刷直流電機矢量控制系統(tǒng)，根據(jù)推導(dǎo)建立了無刷直流電機矢量控制系統(tǒng)的仿真模型，通過仿真驗證了基于勵磁電流分量為零的無刷直流電機矢量控制系統(tǒng)在理論上的可行性與可靠性。 其次，給出了控制系統(tǒng)的軟硬件設(shè)計，硬件使用IPS-2電氣信息綜合實驗系統(tǒng)，功率電路部分選用的是智能功率模塊IPM，并以此為核心進行相應(yīng)電路的設(shè)計，而控制電路則是選用TI公司的DSP芯片TMS320F2812作為核心處理器。論文實現(xiàn)了控制策略的DSP編程，在DSP中完成了基于勵磁分量為零的控制算法，實現(xiàn)了對電機的控制。 為了便于調(diào)試，論文還設(shè)計編寫了基于LabVIEW電機運行狀態(tài)監(jiān)控系統(tǒng)，，這樣使得調(diào)試過程更加直觀，方便。 最后進行了聯(lián)機調(diào)試，將本文得到的實驗結(jié)果和使用其他算法的文獻中的實驗結(jié)果進行對比，說明本文提出的控制系統(tǒng)具有更好的動態(tài)性能。
[Abstract]:With the development and progress of power electronic devices and permanent magnetic materials, brushless DC motor appears, which replaces the mechanical commutator of ordinary DC motor with electronic commutator. The problems of commutating spark, brush wear, large maintenance, electromagnetic interference and so on in commutating process of DC motor are eliminated, and the life of motor is prolonged. With proper control strategy, brushless DC motor can have the same advantages as common DC motor, such as wide speed range, stable operation, large torque, high power density, etc. So the study of brushless DC motor control system has profound significance. Firstly, the paper introduces the background and significance of brushless DC motor, explains the advantages and application fields of brushless DC motor, deduces the dynamic mathematical model of brushless DC motor, and describes the working principle of brushless DC motor. The control simulation module of brushless DC motor is built. The theory of vector control is studied, coordinate transformation and SVPWM control are deeply studied, the mathematical equation of id=0 vector control is deduced, and a brushless DC motor vector control system based on zero excitation current component is designed. The simulation model of the brushless DC motor vector control system is established according to the derivation. The feasibility and reliability of the brushless DC motor vector control system based on zero excitation current component are verified by simulation. Secondly, the hardware and software design of the control system is given. The IPS-2 electrical information synthesis experiment system is used in the hardware, and the intelligent power module is used in the power circuit. The control circuit uses TI's DSP chip TMS320F2812 as the core processor. In this paper, the DSP programming of the control strategy is realized, and the control algorithm based on zero excitation component is completed in DSP, and the control of the motor is realized. In order to facilitate debugging, the paper also designs and compiles the monitoring system of motor running status based on LabVIEW, which makes the debugging process more intuitive and convenient. Finally, the on-line debugging is carried out, and the experimental results obtained in this paper are compared with those in the literature using other algorithms. The results show that the proposed control system has better dynamic performance.
