【摘要】：隨著工業(yè)技術(shù)水平的不斷發(fā)展,多電機同步驅(qū)動控制技術(shù)已經(jīng)被應(yīng)用到各個領(lǐng)域,例如造紙機、印刷機、紡織機、多自由度數(shù)控機床,甚至大功率的高速鐵路牽引系統(tǒng)等等。這些領(lǐng)域的同步控制性能直接影響著產(chǎn)品的質(zhì)量水平、合格率,以及用戶的安全。由于每臺被控電機的技術(shù)參數(shù)(額定功率、負載大小、抗擾動能力等等)都有所不同,這對電機同步性能提出了較高的要求。與此同時,永磁同步電機憑借其自身高效率、高轉(zhuǎn)矩電流比、高能量密度、以及節(jié)能和運行穩(wěn)定的特點,成為工業(yè)領(lǐng)域電機應(yīng)用的最新發(fā)展趨勢。所以針對多永磁同步電機傳動系統(tǒng)的同步控制策略研究具有非常重要的意義。 首先,本文針對單個永磁同步電機進行了控制算法的比較,即矢量控制和直接轉(zhuǎn)矩控制兩者之間的性能比較,總結(jié)了兩者各自的特點。然后,在此基礎(chǔ)上,本文對主令控制、主從控制、交叉耦合控制、虛擬主軸控制等四種同步控制策略進行了分析。通過Matlab/Simulink建模仿真,對比了這四種控制策略的起動響應(yīng)、同步精度和抗干擾能力等各項指標(biāo)。基于數(shù)據(jù)結(jié)果的分析,總結(jié)得出每種同步控制策略的優(yōu)缺點和各自的適用范圍。最終發(fā)現(xiàn),針對高速鐵路牽引同步系統(tǒng)這一應(yīng)用場合,基于虛擬主軸的多電機矢量控制是首選方案。 為了進一步改善系統(tǒng)的性能,本文將模糊理論與傳統(tǒng)的PID控制器進行了結(jié)合,使模糊PID控制器應(yīng)用到矢量控制系統(tǒng)中,實現(xiàn)了參數(shù)的自整定,優(yōu)化了系統(tǒng)性能。在此基礎(chǔ)上,本文以CRH2高速列車的“四動四拖”結(jié)構(gòu)作為原型,實現(xiàn)了四臺600kW永磁同步電機的虛擬主軸同步控制系統(tǒng),并且將模糊PID控制器應(yīng)用其中,以此模擬一節(jié)動車的同步系統(tǒng)。 本文最后總結(jié)所做的研究工作,將多電機同步控制算法研究中出現(xiàn)的問題進行了闡述,并對未來的進一步系統(tǒng)的研究進行了展望。
[Abstract]:With the development of industrial technology, multi-motor synchronous drive control technology has been applied to various fields, such as paper machine, printing machine, textile machine, multi-degree-of-freedom numerical control machine, even high-power high-speed railway traction system and so on. The performance of synchronous control in these fields directly affects the quality level, the qualified rate, and the safety of users. Because the technical parameters (rated power, load size, anti-disturbance ability, etc.) of each controlled motor are different, the synchronous performance of the motor is required to be high. At the same time, permanent magnet synchronous motor (PMSM), with its high efficiency, high torque / current ratio, high energy density, energy saving and stable operation, has become the latest development trend of motor application in industrial field. Therefore, it is of great significance to study the synchronous control strategy of multi-permanent magnet synchronous motor transmission system. Firstly, the control algorithms of PMSM are compared, that is, the performance of vector control and direct torque control are compared, and their respective characteristics are summarized. Then, on this basis, this paper analyzes four synchronous control strategies: master order control, master slave control, cross coupling control and virtual spindle control. Through Matlab/Simulink modeling and simulation, the starting response, synchronization accuracy and anti-jamming ability of the four control strategies are compared. Based on the analysis of data results, the advantages and disadvantages of each synchronous control strategy and its application range are summarized. Finally, it is found that multi-motor vector control based on virtual spindle is the first choice for high-speed railway traction synchronization system. In order to further improve the performance of the system, the fuzzy theory and the traditional PID controller are combined in this paper. The fuzzy PID controller is applied to the vector control system, which realizes the self-tuning of the parameters and optimizes the performance of the system. On this basis, taking the "four-action four-towing" structure of the CRH2 high-speed train as the prototype, the virtual spindle synchronous control system of four 600kW permanent magnet synchronous motors is realized, and the fuzzy PID controller is applied in the system. This simulates the synchronous system of a motor car. Finally, this paper summarizes the research work done, describes the problems in the research of multi-motor synchronous control algorithm, and looks forward to further systematic research in the future.
