    摘要:

    設(shè)計(jì)了一種用于電感參數(shù)辨識的高頻響應(yīng)電流處理方法，辨識出了電機(jī)的直、交軸電感參數(shù)，并且分析推導(dǎo)了逆變器非線性因素對電感參數(shù)辨識精度的影響。通過對響應(yīng)電流進(jìn)行兩個(gè)延時(shí)濾波和兩個(gè)同步軸濾波分析，剔除了基波和其他高頻雜波，精確地得到高頻電流的正、負(fù)相序幅值，辨識出了直、交軸電感參數(shù)。該在線參數(shù)辨識方法不僅在電機(jī)靜止時(shí)能進(jìn)行辨識，而且在電機(jī)正常運(yùn)行的各個(gè)負(fù)載和速度下也能辨識出電感。電機(jī)實(shí)驗(yàn)結(jié)果表明，在不同負(fù)載和轉(zhuǎn)速下的直、交軸電感辨識結(jié)果準(zhǔn)確度較高，有助于電機(jī)驅(qū)動(dòng)系統(tǒng)性能的改進(jìn)。

    Abstract:

    A method of high frequency current processing was proposed for inductance parameters identification. The d-axis and q-axis inductance parameters were identified. The effect of inverters nonlinear factors on identification accuracy of inductance parameters was analyzed and deduced. The base current and other high frequency clutter current were excluding by applying two delay filters and two synchronous axis filters on response current. The positive and negative phase’s amplitude were obtained. The d-axis and q-axis inductance were identified. The proposed method could identify inductance in the stationary state and operating state of the motor. The results showed that under the different loads and speeds of motor, the accuracy of inductance identification was high. It could give a help for improving the real driving control system. 
