【摘要】：20世紀(jì)70年代初，矢量控制技術(shù)的問(wèn)世使得交流電動(dòng)機(jī)能夠獲得與直流電動(dòng)機(jī)相仿的高動(dòng)態(tài)性能，給交流調(diào)速系統(tǒng)帶來(lái)了巨大的變革。論文主要討論了矢量控制的基本思想，在基于模型參考自適應(yīng)的理論基礎(chǔ)上，設(shè)計(jì)出了異步電機(jī)的無(wú)速度傳感器矢量控制系統(tǒng)，在仿真的基礎(chǔ)上進(jìn)行了相關(guān)的實(shí)驗(yàn)，取得了較好的效果。論文主要的研究?jī)?nèi)容包括： (1)通過(guò)對(duì)矢量控制原理的探討，分析矢量控制方式的優(yōu)缺點(diǎn)并結(jié)合空間電壓矢量脈寬調(diào)制技術(shù)(SVPWM)，建立異步電機(jī)的矢量控制系統(tǒng)。 (2)先對(duì)模型參考自適應(yīng)的理論支持(Popov超穩(wěn)定性理論)做了相應(yīng)的探討，然后對(duì)它的基本思想和三種不同的模型參考自適應(yīng)方法做了詳細(xì)的介紹和對(duì)比分析，最后選擇了合適的方法，在矢量控制的基礎(chǔ)上建立了基于無(wú)速度傳感器的異步電機(jī)矢量控制模型。 (3)在Matlab/Simulink環(huán)境中分別搭建出上述的異步電機(jī)有速度傳感器和無(wú)速度傳感器的控制系統(tǒng)仿真，從得到的仿真實(shí)驗(yàn)結(jié)果分析得知：異步電機(jī)在有速度傳感器和無(wú)速度傳感器的控制系統(tǒng)中，無(wú)論是在低速運(yùn)行、高速運(yùn)行、轉(zhuǎn)速突變，還是在電機(jī)空載啟動(dòng)、帶負(fù)載啟動(dòng)的情況下，上述的異步電機(jī)控制系統(tǒng)都表現(xiàn)出了良好的性能，達(dá)到了設(shè)計(jì)的要求。 (4)本課題的實(shí)驗(yàn)部分以TMS320F2812DSP為控制核心，搭建了異步電機(jī)有速度傳感器的矢量控制數(shù)字化平臺(tái)，，根據(jù)仿真模塊編寫(xiě)出相應(yīng)模塊的子程序并在軟件CCS3.1中進(jìn)行程序調(diào)試，實(shí)驗(yàn)結(jié)果驗(yàn)證了本文異步電機(jī)交流控制系統(tǒng)的可行性。
[Abstract]:At the beginning of 1970s, the advent of vector control technology enabled AC motor to obtain high dynamic performance similar to DC motor, which brought great changes to AC speed regulation system. This paper mainly discusses the basic idea of vector control. Based on the model reference adaptive theory, the speed sensorless vector control system of asynchronous motor is designed, and the relevant experiments are carried out on the basis of simulation. Good results have been achieved. The main contents of this thesis are as follows: 1) by discussing the principle of vector control, analyzing the merits and demerits of vector control mode and combining space voltage vector pulse width modulation (SVPWM) technique, the vector control system of asynchronous motor is established. (2) this paper first discusses the theory of model reference adaptation supporting Popov's hyperstability theory, and then gives a detailed introduction and comparative analysis of its basic idea and three different model reference adaptive methods. Finally, an appropriate method is selected and a speed sensorless vector control model of asynchronous motor is established based on vector control. The simulation of the control system of the asynchronous motor with speed sensor and no speed sensor is built in the Matlab/Simulink environment. The analysis of the simulation results shows that the asynchronous motor in the speed sensor and speed sensorless control system, whether in the low speed operation, high speed operation, rotational speed mutation, or in the motor no load start, In the case of load starting, the above control system of asynchronous motor shows good performance and meets the design requirements. In the experiment part of this project, the digital platform of vector control of asynchronous motor with speed sensor is built with TMS320F2812DSP as the control core. According to the simulation module, the subprogram of the corresponding module is compiled and debugged in the software CCS3.1. The experimental results verify the feasibility of the AC control system of asynchronous motor in this paper.
