PLC系(xi)統中的(de)(de)(de)(de)PID控制器（Proportional-Integral-Derivative Controller）是一(yi)(yi)種常用(yong)的(de)(de)(de)(de)控制算法，用(yong)于(yu)自動調節(jie)(jie)系(xi)統的(de)(de)(de)(de)輸出(chu)，以(yi)(yi)(yi)(yi)使系(xi)統的(de)(de)(de)(de)實(shi)際(ji)值接(jie)近(jin)(jin)預設值。PID控制器的(de)(de)(de)(de)作(zuo)(zuo)(zuo)用(yong)主(zhu)要有以(yi)(yi)(yi)(yi)下幾個方(fang)面：比(bi)(bi)例(li)作(zuo)(zuo)(zuo)用(yong)（Proportional Action）：根據實(shi)際(ji)值與(yu)預設值之間(jian)的(de)(de)(de)(de)差異，以(yi)(yi)(yi)(yi)一(yi)(yi)定的(de)(de)(de)(de)比(bi)(bi)例(li)關(guan)系(xi)調節(jie)(jie)輸出(chu)。當(dang)實(shi)際(ji)值偏離預設值較大時，比(bi)(bi)例(li)作(zuo)(zuo)(zuo)用(yong)會快速(su)調整輸出(chu)，以(yi)(yi)(yi)(yi)盡快將實(shi)際(ji)值接(jie)近(jin)(jin)預設值。積分(fen)(fen)作(zuo)(zuo)(zuo)用(yong)（Integral Action）：根據實(shi)際(ji)值與(yu)預設值的(de)(de)(de)(de)累積誤差，以(yi)(yi)(yi)(yi)一(yi)(yi)定的(de)(de)(de)(de)積分(fen)(fen)關(guan)系(xi)調節(jie)(jie)輸出(chu)。積分(fen)(fen)作(zuo)(zuo)(zuo)用(yong)可以(yi)(yi)(yi)(yi)消(xiao)除比(bi)(bi)例(li)作(zuo)(zuo)(zuo)用(yong)無法完全消(xiao)除的(de)(de)(de)(de)穩態誤差，使系(xi)統更加穩定。微(wei)(wei)分(fen)(fen)作(zuo)(zuo)(zuo)用(yong)（Derivative Action）：根據實(shi)際(ji)值的(de)(de)(de)(de)變化速(su)率，以(yi)(yi)(yi)(yi)一(yi)(yi)定的(de)(de)(de)(de)微(wei)(wei)分(fen)(fen)關(guan)系(xi)調節(jie)(jie)輸出(chu)。微(wei)(wei)分(fen)(fen)作(zuo)(zuo)(zuo)用(yong)可以(yi)(yi)(yi)(yi)預測(ce)實(shi)際(ji)值的(de)(de)(de)(de)變化趨勢，避免系(xi)統的(de)(de)(de)(de)過沖和震蕩。河北化工(gong)PLC系(xi)統軟件(jian)
