運(yùn)動(dòng)控制概論期末報(bào)告資料出處︰無速度感測(cè)器之直接轉(zhuǎn)矩-資料下載頁
【導(dǎo)讀】感應(yīng)馬達(dá)在本身結(jié)構(gòu)特性上有許多的優(yōu)點(diǎn)，如架構(gòu)堅(jiān)固、亦於維護(hù)、價(jià)格便宜等優(yōu)點(diǎn)，所以在工業(yè)應(yīng)用的場(chǎng)合中，感應(yīng)馬達(dá)是扮演了相當(dāng)重要的角色。近幾年來更由於向量。地成為市場(chǎng)上的主流。然而在高性能的感應(yīng)馬達(dá)控制中，為了使整個(gè)轉(zhuǎn)速操作。性及系統(tǒng)的可靠度。因此在本論文中將設(shè)計(jì)無感測(cè)器系統(tǒng)，以避免感測(cè)器所。造成上述的問題。設(shè)計(jì)的方式是以端電壓及線電流的回授，並且針對(duì)傳統(tǒng)無感測(cè)器系統(tǒng)在加載操作情況下，矩?zé)o。輸出，增加系統(tǒng)的可行性與實(shí)用性。由於本論文所設(shè)計(jì)的無感測(cè)器系統(tǒng)是以直接轉(zhuǎn)矩控制為。基礎(chǔ)，所以其效能是直接的受到磁通估測(cè)準(zhǔn)確性所影響。在感應(yīng)馬達(dá)的驅(qū)動(dòng)器設(shè)計(jì)上，編碼器。將大幅提高硬體的成本，並不符合經(jīng)濟(jì)上的效益。作控制，所以非常適合需轉(zhuǎn)矩響應(yīng)快速的場(chǎng)合；言，此種向量控制方式其系統(tǒng)強(qiáng)健性也較高。前一章節(jié)的系統(tǒng)是使用編碼器完成速度。qs是固定在靜止的定子座標(biāo)。定子磁通估算發(fā)生錯(cuò)誤，會(huì)直接的造成直接轉(zhuǎn)矩。所以由上述可知，對(duì)
