施耐德系統(tǒng)TSXASZ200

TSXASZ200功能用于對(duì)閉環(huán)過程進(jìn)行控制。PID控制適用于溫度、壓力和流量等物理量，是工業(yè)現(xiàn)場中應(yīng)用為廣泛的一種控制方式，其原理是對(duì)被控對(duì)象設(shè)定一個(gè)給定值然后將實(shí)際值測量出來，并與給定值比較，將其差值送入PID控制器，PID控制器按照的運(yùn)算規(guī)律，計(jì)算出結(jié)果，即為輸出值，送到執(zhí)行器進(jìn)行調(diào)節(jié)，其中的P、I和D指的是比例、積分和微分，是一種閉環(huán)控制算法。通過這些參數(shù)，可以使被控對(duì)象追隨給定值變化并使系統(tǒng)達(dá)到穩(wěn)定，自動(dòng)各種干擾對(duì)控制過程的影響。
