【摘要】：繞組分段永磁同步直線電機(jī)(WS-PMLSM)定子特殊的分段結(jié)構(gòu)導(dǎo)致動(dòng)子在跨段過程中各關(guān)鍵電磁參數(shù)將隨動(dòng)子位置改變而劇烈變化,從而將給實(shí)施無位置傳感器控制帶來巨大的挑戰(zhàn)與困難。為解決這一問題,首先利用有限元分析及實(shí)驗(yàn)測試的方法對(duì)動(dòng)子跨段過程中關(guān)鍵電磁參數(shù)的非線性變化規(guī)律進(jìn)行分析,從而構(gòu)建WS-PMLSM的精確數(shù)學(xué)模型;然后針對(duì)相鄰兩段定子觀測反電動(dòng)勢信號(hào)幅值變化的規(guī)律,提出基于反饋?zhàn)赃m應(yīng)滑模觀測器的段間觀測反電動(dòng)勢同步合成法,以取得段間磁極位置的精確辨識(shí),最終實(shí)現(xiàn)其在寬調(diào)速范圍內(nèi)全行程無傳感器電流-速度雙閉環(huán)運(yùn)行;最后對(duì)所提算法進(jìn)行仿真分析和實(shí)驗(yàn)測試,結(jié)果證明該方法有效可行。
[Abstract]:The special subsection structure of the stator of the winding segment permanent magnet synchronous linear motor (WS-PMLSM) causes the key electromagnetic parameters of the actuator to change the position of the actuator and change dramatically during the cross-section process. In order to solve this problem, the nonlinear variation of the key electromagnetic parameters in the cross-section of the actuator is analyzed by using the finite element analysis and the experimental test method, which will bring great challenges and difficulties to the implementation of the sensorless control. The accurate mathematical model of WS-PMLSM is constructed, and the synchronous synthesis method based on feedback adaptive sliding mode observer is proposed to synchronize the observed backEMF signals between adjacent two stator segments, which is based on feedback adaptive sliding mode observer, according to the rule of amplitude variation of the signal of BEMF observed by adjacent two-stage stator. In order to obtain the accurate identification of the magnetic pole position between segments, the sensorless current-velocity double closed-loop operation is finally realized in the wide speed range. Finally, the simulation analysis and experimental test of the proposed algorithm are carried out, and the results show that the proposed method is effective and feasible.
