BISON GEAR減速電機
伺服電機可使控制速度,，位置精度非常準確，可以將電壓信號轉(zhuǎn)化為轉(zhuǎn)矩和轉(zhuǎn)速以驅(qū)動控制對象,。伺服電機轉(zhuǎn)子轉(zhuǎn)速受輸入信號控制,，并能快速反應，在自動控制系統(tǒng)中,，用作執(zhí)行元件,，且具有機電時間常數(shù)小、線性度高,、始動電壓等特性,，可把所收到的電信號轉(zhuǎn)換成電動機軸上的角位移或角速度輸出。分為直流和交流伺服電動機兩大類,，其主要特點是，當信號電壓為零時無自轉(zhuǎn)現(xiàn)象,，轉(zhuǎn)速隨著轉(zhuǎn)矩的增加而勻速下降

采用以恒壓頻比方式工作的通用變頻器來直接驅(qū)動感應電機在工業(yè)生產(chǎn)領(lǐng)域中應用很廣泛,。在不改變原有的恒壓頻比變頻調(diào)速系統(tǒng)結(jié)構(gòu)的前提下，進一步提高該系統(tǒng)的控制性能意義很大,。該文根據(jù)恒壓頻比控制的特點,，把通用變頻器和感應電機看成一個整體——恒壓頻比變頻調(diào)速系統(tǒng)，給出了相應的數(shù)學模型,，并得出了適用于帶補償和不帶補償?shù)暮銐侯l比運行方式的逆系統(tǒng)模型，進一步構(gòu)造神經(jīng)網(wǎng)絡逆系統(tǒng)并與恒壓頻比變頻調(diào)速系統(tǒng)串聯(lián)復合成偽線性系統(tǒng),，再設(shè)計線性閉環(huán)調(diào)節(jié)器實現(xiàn)高性能控制。實驗結(jié)果證明了采用神經(jīng)網(wǎng)絡逆控制方法可以使恒壓頻比變頻調(diào)速系統(tǒng)獲得優(yōu)良的運行性能,。
