對于IPMSM,將dq軸電壓作為參考模型和可調(diào)模型的輸入,將實際電流和估計電流分別作為參考模型和可調(diào)模型的輸出,誤差信號為實際電流與估計電流的差值。
IPMSM 系統(tǒng)可以將電壓狀態(tài)空間方程改寫為如下式所示
MRAS參數(shù)辨識系統(tǒng)中的參考模型可由式上所體現(xiàn),為了分析計算方便,將上式化簡為
IPMSM 中轉(zhuǎn)速ωe以及磁鏈ψf可認(rèn)定為保持恒定,因此可將MRAS參數(shù)辨識系統(tǒng)中的參考模型改成可調(diào)模型如公司主要經(jīng)營歐美日大型控制系統(tǒng)備件、可編程控制器備件、工業(yè)機器人備件、伺服控制系統(tǒng)備件、人機界面、變頻器、編碼器、傳感器、儀器儀表、液壓氣動等種類繁多的產(chǎn)品,并以合理的價格、快捷的交貨、良好的售后服務(wù),贏得廣大國內(nèi)外客戶的認(rèn)可和信任。中海德聯(lián)系人:陳工 電話號碼:180-0500-6671
