異步電機(jī)調(diào)壓調(diào)速控制系統(tǒng)設(shè)計(jì)及仿真

1、摘要我國(guó)工業(yè)不斷發(fā)展。機(jī)械化對(duì)調(diào)速系統(tǒng)的性能和精度要求越來(lái)越高。實(shí)現(xiàn)電機(jī)調(diào)速有不少方法。研究電機(jī)調(diào)速，找出符合實(shí)際的調(diào)速方法能最大限度的節(jié)約能源，所以研究調(diào)壓調(diào)速就顯得很有必要。異步電機(jī)調(diào)壓調(diào)速控制系統(tǒng)是一種比較簡(jiǎn)單實(shí)用的調(diào)速系統(tǒng)，該系統(tǒng)具有良好的運(yùn)行、控制及經(jīng)濟(jì)性能，顯示出巨大的發(fā)展?jié)摿?。本設(shè)計(jì)分析了異步電機(jī)調(diào)速的原理，介紹了MATLAB的相關(guān)知識(shí)，并通過(guò)MATLAB軟件分別對(duì)異步電機(jī)開(kāi)環(huán)控制系統(tǒng)與速度反饋閉環(huán)控制系統(tǒng)進(jìn)行了仿真。電機(jī)

2、調(diào)速開(kāi)環(huán)控制系統(tǒng)調(diào)速范圍較小，采用速度作為負(fù)反饋的閉環(huán)控制系統(tǒng)解決了這個(gè)問(wèn)題。使調(diào)速性能得到改善。本設(shè)計(jì)對(duì)這兩種系統(tǒng)分別進(jìn)行可分析。關(guān)鍵詞：異步電機(jī)；調(diào)壓調(diào)速；控制；仿真摘要.....................................................................................................................................
