機(jī)電控制是研究如何設(shè)計(jì)控制器并合理選擇或設(shè)計(jì)放大元件、執(zhí)行元件、檢測(cè)與轉(zhuǎn)換元件、導(dǎo)向與支承元件和傳動(dòng)機(jī)構(gòu)等,并由此組成機(jī)電控制系統(tǒng)使機(jī)電設(shè)備達(dá)到所要求的性能的一門科學(xué),在機(jī)電一體化技術(shù)中占有非常重要的地位。
機(jī)電控制系統(tǒng)是機(jī)電一體化產(chǎn)品及系統(tǒng)中承擔(dān)著控制對(duì)象輸出,并按照指令規(guī)定的規(guī)律變化的功能單元,是機(jī)電一體化產(chǎn)品及系統(tǒng)的重要組成部分。機(jī)電控制系統(tǒng)是一種自動(dòng)控制系統(tǒng)。
機(jī)電控制系統(tǒng)一般由指令元件,比較、綜合與放大元件,轉(zhuǎn)換與功率放大元件、執(zhí)行元件、工作機(jī)構(gòu)、檢測(cè)與轉(zhuǎn)換元件等6部分組成。
機(jī)電控制系統(tǒng)的工作原理是:有指令元件發(fā)出指令,通過(guò)比較、綜合與放大元件將此信號(hào)與輸出反饋信號(hào)比較,再將差值進(jìn)行處理和放大、控制及轉(zhuǎn)換,將此處理后的信號(hào)加到功率放大元件并施加到執(zhí)行元件的輸入信號(hào),使得執(zhí)行元件按指令的要求運(yùn)動(dòng);而執(zhí)行元件往往和機(jī)電裝備的工作機(jī)構(gòu)相連接,從而使機(jī)電裝備的被控量(如位移、速度、力、轉(zhuǎn)矩等)符合所要求的規(guī)律。
