過程控制，過程控制是指對溫度、壓力、流量等模擬量的閉環(huán)控制。作為工業(yè)控制計(jì)算機(jī)，PLC能編制各種各樣的控制算法程序，完成閉環(huán)控制。PID調(diào)節(jié)是一般閉環(huán)控制系統(tǒng)中用得較多的調(diào)節(jié)方法。大中型PLC都有PID模塊，目前許多小型PLC也具有此功能模塊。PID處理一般是運(yùn)行專用的PID子程序。過程控制在冶金、化工、熱處理、鍋爐控制等場合有非常廣泛的應(yīng)用。

PLC的工作原理，PLC是采用"順序掃描，不斷循環(huán)"的方式進(jìn)行工作的。即在PLC運(yùn)行時(shí)，CPU根據(jù)用戶按控制要求編制好并存于用戶存儲(chǔ)器中的程序，按指令步序號(hào)（或地址號(hào)）作周期性循環(huán)掃描，如無跳轉(zhuǎn)指令，則從第一條指令開始逐條順序執(zhí)行用戶程序，直至程序結(jié)束。然后重新返回第一條指令，開始下一輪新的掃描。在每次掃描過程中，還要完成對輸入信號(hào)的采樣和對輸出狀態(tài)的刷新等工作。

運(yùn)行性能不同，步進(jìn)電機(jī)的控制為開環(huán)控制，啟動(dòng)頻率過高或負(fù)載過大易出現(xiàn)丟步或堵轉(zhuǎn)的現(xiàn)象，停止時(shí)轉(zhuǎn)速過高易出現(xiàn)過沖的現(xiàn)象，所以為保證其控制精度，應(yīng)處理好升、降速問 題。交流伺服驅(qū)動(dòng)系統(tǒng)為閉環(huán)控制，驅(qū)動(dòng)器可直接對電機(jī)編碼器反饋信號(hào)進(jìn)行采樣，內(nèi)部構(gòu)成位置環(huán)和速度環(huán)，一般不會(huì)出現(xiàn)步進(jìn)電機(jī)的丟步或過沖的現(xiàn)象，控制性 能更為可靠。
