【摘要】：永磁同步電機(jī)(Permanent Magnet Synchronous Motor—PMSM)結(jié)構(gòu)簡(jiǎn)單、運(yùn)行可靠、抗干擾力比較強(qiáng)、跟蹤誤差較小、超調(diào)量較小、響應(yīng)快速,又具有體積小、效率高、力矩大魯棒信好等各種優(yōu)點(diǎn),因此已經(jīng)在眾多伺服控制領(lǐng)域中得到了普遍的應(yīng)用。本文的研究是基于模糊滑模變結(jié)構(gòu)控制的PMSM矢量控制。本文先從PMSM的數(shù)學(xué)模型出發(fā),介紹PMSM的數(shù)學(xué)模型以及其的控制理論和磁鏈跟蹤控制技術(shù)(SVPWM)。然后利用MATLAB/simulink仿真軟件,搭建永磁同步電機(jī)的矢量控制系統(tǒng)的仿真模型,并對(duì)雙閉環(huán)下永磁同步電機(jī)的矢量控制系統(tǒng)進(jìn)行仿真實(shí)驗(yàn)。目前永磁同步電機(jī)的矢量控制系統(tǒng)大都采用PID控制,但是永磁同步電機(jī)的矢量控制系統(tǒng)本身具有非線性、復(fù)雜性和時(shí)變性等特性,使得普通PID控制難以獲得較好的控制特性�；Ｗ兘Y(jié)構(gòu)控制存在抖振的危害,指數(shù)趨近律能夠有效的消弱抖振,卻不能去除抖振；在此基礎(chǔ)上,分析模糊控制的優(yōu)式,可以有效的消除抖振。為了提升PMSM伺服系統(tǒng)的控制特性,本文通過(guò)采用基于模糊滑模變結(jié)構(gòu)控制的速度控制方法。通過(guò)模糊滑模變結(jié)構(gòu)控制器對(duì)速度調(diào)節(jié)器進(jìn)行優(yōu)化,此算法根據(jù)電機(jī)運(yùn)行過(guò)程中速度的變化量,通過(guò)模糊控制規(guī)則對(duì)滑模變結(jié)構(gòu)控制中的兩個(gè)參數(shù)(k,ε)進(jìn)行在線調(diào)節(jié),進(jìn)而達(dá)到優(yōu)化的目的。同時(shí)通過(guò)對(duì)模糊滑模變結(jié)構(gòu)控制、滑模變結(jié)構(gòu)控制及普通PID控制的三種速度控制器的PMSM矢量控制進(jìn)行仿真實(shí)驗(yàn),并對(duì)實(shí)驗(yàn)結(jié)果進(jìn)行細(xì)致分析和比較,結(jié)果表明基于模糊滑模變結(jié)構(gòu)控制的永磁同步電機(jī)矢量控制相對(duì)于基于普通PID控制器的及基于滑模變結(jié)構(gòu)控制的永磁同步電機(jī)矢量控制系統(tǒng)具有速度響應(yīng)快、超調(diào)量少、速度波動(dòng)小等優(yōu)點(diǎn),其魯棒性及動(dòng)靜態(tài)性能都相對(duì)優(yōu)于普通PID控制器的及基于滑模變結(jié)構(gòu)控制的永磁同步電機(jī)矢量控制。在相關(guān)控制原理和控制策略基礎(chǔ)上結(jié)合矢量控制系統(tǒng)的仿真實(shí)驗(yàn)研究上,從硬件系統(tǒng)構(gòu)建的整體思路出發(fā),進(jìn)行設(shè)計(jì)以數(shù)字信號(hào)處理器(DSP) TMS320LF2407A為核心的永磁同步電機(jī)矢量控制硬件系統(tǒng),并闡述TMS320LF2407A的最小系統(tǒng)及其外圍電路、主功率電路、檢測(cè)及保護(hù)電路等。以CCS 3.3 (Code Composer Studio 3.3)為軟件平臺(tái),從永磁同步電機(jī)矢量控制系統(tǒng)的控制思路出發(fā),分別詳細(xì)對(duì)系統(tǒng)的主程序、中斷服務(wù)子程序以及控制算法進(jìn)行設(shè)計(jì)與說(shuō)明。在系統(tǒng)軟硬件的基礎(chǔ)之上對(duì)系統(tǒng)進(jìn)行調(diào)試和測(cè)試。
[Abstract]:Permanent magnet synchronous motor (Permanent Magnet Synchronous Motor PMSM) has the advantages of simple structure, reliable operation, strong anti-interference capacity, the tracking error is small, small overshoot, fast response, and has the advantages of small size, high efficiency, large torque and good robust signal, so has been in many fields to get a servo control universal application. The research of this paper is based on the PMSM vector control of fuzzy sliding mode variable structure control. Starting from the mathematical model of PMSM, this paper introduces the mathematical model of PMSM and its control theory and magnetic chain tracking control technology (SVPWM). Then, the simulation model of permanent magnet synchronous motor vector control system is built by using MATLAB/simulink simulation software, and the simulation experiment of vector control system of double closed loop permanent magnet synchronous motor is carried out. At present, most of the vector control systems of permanent magnet synchronous motor are controlled by PID. However, the vector control system of PMSM is nonlinear, complex and time-varying, which makes it difficult for ordinary PID control to get better control characteristics. The sliding mode variable structure control has the danger of chattering. The exponential reaching law can effectively weaken chattering, but it can not eliminate chattering. Based on that, the analysis of fuzzy control's superiority can effectively eliminate chattering. In order to improve the control characteristics of the PMSM servo system, the speed control method based on fuzzy sliding mode variable structure control is adopted in this paper. A fuzzy sliding mode variable structure controller is used to optimize the speed controller. According to the speed change in the motor running process, the algorithm adjuster the two parameters of the sliding mode variable structure (k, e) online by fuzzy control rules, so as to achieve the purpose of optimization. At the same time through the simulation of PMSM vector of variable structure control, sliding mode variable structure control and conventional PID control in the three kinds of speed controller of fuzzy sliding mode control, and the experimental results are detailed analysis and comparison results show that the fuzzy sliding mode variable structure control of permanent magnet synchronous motor vector control compared with conventional PID controller and PMSM motor vector control system based on sliding mode variable structure control with fast response, less overshoot, speed advantages such as small fluctuations based on its robustness and dynamic performance are relatively better than the ordinary PID controller and based on permanent magnet synchronous motor vector control sliding mode variable structure control. The control principle and control strategy based on the combination of simulation and Experimental Research on vector control system, starting from the overall train of thought of construction of the hardware system, designed based on digital signal processor (DSP) TMS320LF2407A permanent magnet synchronous motor vector control hardware system as the core, and describes the TMS320LF2407A minimum system and peripheral circuit, power circuit, detection and protection circuit etc.. Taking CCS 3.3 (Code Composer Studio 3.3) as the software platform, starting from the control idea of PMSM vector control system, the main program, interrupt service subroutine and control algorithm of the system are designed and explained in detail. The system is debugged and tested on the basis of the software and hardware of the system.
