【摘要】：傳統(tǒng)電壓型磁鏈算法在對電機(jī)內(nèi)普遍存在的橢圓形磁場磁鏈進(jìn)行辨識時(shí)存在穩(wěn)態(tài)幅值相位誤差。為此文中提出兩種新型磁鏈算法,新算法基于反電動(dòng)勢矢量與磁鏈?zhǔn)噶康年P(guān)系得到。通過在同步旋轉(zhuǎn)坐標(biāo)系下低通濾波消除積分漂移;通過旋轉(zhuǎn)矢量,實(shí)現(xiàn)積分作用。新算法結(jié)構(gòu)簡單,易于工程實(shí)現(xiàn)。仿真結(jié)果表明:新算法有效消除了積分漂移,算法1可以對圓形磁場磁鏈進(jìn)行準(zhǔn)確辨識;算法2可以對橢圓形磁場磁鏈進(jìn)行準(zhǔn)確的辨識;對于橢圓形磁場磁鏈,算法1辨識出其與電機(jī)轉(zhuǎn)向相同的圓形分量。將新算法應(yīng)用于一臺表貼式永磁同步電機(jī)無位置傳感器調(diào)速系統(tǒng)的轉(zhuǎn)子位置估算,利用數(shù)字信號處理器TMS320F2812DSP對其進(jìn)行了數(shù)字化實(shí)現(xiàn)。系統(tǒng)在穩(wěn)態(tài)與電機(jī)轉(zhuǎn)速突變時(shí)具有良好的靜態(tài)、動(dòng)態(tài)特性,證明了新算法的有效性和實(shí)際可應(yīng)用性。
[Abstract]:The traditional voltage type magnetic flux linkage algorithm has the steady-state amplitude phase error when identifying the elliptical magnetic flux linkage in the motor. In this paper, two new magnetic chain algorithms are proposed. The new algorithm is based on the relationship between the anti electromotive force vector and the magnetic chain vector. The new algorithm has simple structure and easy to implement. The simulation results show that the new algorithm effectively eliminates the integral drift. Algorithm 1 can identify the circular magnetic flux linkage accurately; algorithm 2 can identify the elliptical magnetic field magnetic chain accurately; for the elliptical magnetic field magnetic chain, the algorithm 1 identifies its electricity and electricity. The new algorithm is used for the same circular component. The new algorithm is applied to the rotor position estimation of a permanent magnet synchronous motor speed control system with a permanent magnet synchronous motor. The digital signal processor TMS320F2812DSP is used to digitize it. The system has good static and dynamic characteristics when the steady state and motor speed change, and the new calculation is proved. The validity of the method and the practical applicability of the method.
