1、學(xué)號(hào):中州大學(xué)電機(jī)及拖動(dòng)課程設(shè)計(jì)題目:轉(zhuǎn)速負(fù)反饋的單閉環(huán)直流調(diào)速系統(tǒng)的設(shè)計(jì)姓名:專業(yè):電氣自動(dòng)化班級(jí):指導(dǎo)老師:趙靜2014年6月10號(hào)摘要該設(shè)計(jì)是轉(zhuǎn)速負(fù)反饋的單閉環(huán)直流調(diào)速系統(tǒng),目前調(diào)速系統(tǒng)分為交流調(diào)速和直流調(diào)速系統(tǒng),由于直流調(diào)速系統(tǒng)的調(diào)速范圍廣、靜差率小、穩(wěn)定性好以及具有良好的動(dòng)態(tài)性能,因此在相當(dāng)長(zhǎng)的時(shí)間內(nèi),高性能的調(diào)速系統(tǒng)幾乎都采用直流調(diào)速系統(tǒng),為了提高直流調(diào)速系統(tǒng)的動(dòng)靜態(tài)性能指標(biāo),通常采用閉環(huán)控制系統(tǒng),對(duì)調(diào)速指標(biāo)要求不高的場(chǎng)合,采用單閉環(huán)系統(tǒng),按反饋的方式不同可分為轉(zhuǎn)速反饋,電流反饋,電壓反饋等。在單閉環(huán)系統(tǒng)中,轉(zhuǎn)
2、速負(fù)反饋單閉環(huán)使用較多。?在設(shè)計(jì)中用MATLAB軟件對(duì)電流環(huán)和轉(zhuǎn)速環(huán)的設(shè)計(jì)舉例進(jìn)行了仿真,通過(guò)比較說(shuō)明了直流調(diào)速系統(tǒng)的特性。關(guān)鍵字:轉(zhuǎn)速負(fù)反饋動(dòng)態(tài)性能IIIABSTRACThedesignspeednegativefeedbackissingleclosed-loopdcspeedregulatingsystem,thecurrentspeedregulationsystemisdividedintoacspeedregulationanddcspeedcontrolsystem,duetothewidescopeofsp
