PLC系(xi)(xi)统(tong)中(zhong)的(de)(de)PID控(kong)制器(qi)（Proportional-Integral-Derivative Controller）是一种常用(yong)(yong)的(de)(de)控(kong)制算法，用(yong)(yong)于自动调(diao)(diao)节(jie)(jie)系(xi)(xi)统(tong)的(de)(de)输出(chu)(chu)，以(yi)使系(xi)(xi)统(tong)的(de)(de)实际(ji)(ji)值(zhi)(zhi)(zhi)(zhi)接近预(yu)(yu)设(she)值(zhi)(zhi)(zhi)(zhi)。PID控(kong)制器(qi)的(de)(de)作用(yong)(yong)主要有以(yi)下几(ji)个方(fang)面：比(bi)例(li)(li)作用(yong)(yong)（Proportional Action）：根(gen)据实际(ji)(ji)值(zhi)(zhi)(zhi)(zhi)与(yu)预(yu)(yu)设(she)值(zhi)(zhi)(zhi)(zhi)之间(jian)的(de)(de)差异，以(yi)一定的(de)(de)比(bi)例(li)(li)关(guan)系(xi)(xi)调(diao)(diao)节(jie)(jie)输出(chu)(chu)。当(dang)实际(ji)(ji)值(zhi)(zhi)(zhi)(zhi)偏离预(yu)(yu)设(she)值(zhi)(zhi)(zhi)(zhi)较大时，比(bi)例(li)(li)作用(yong)(yong)会快速调(diao)(diao)整(zheng)输出(chu)(chu)，以(yi)尽快将实际(ji)(ji)值(zhi)(zhi)(zhi)(zhi)接近预(yu)(yu)设(she)值(zhi)(zhi)(zhi)(zhi)。积(ji)分(fen)(fen)作用(yong)(yong)（Integral Action）：根(gen)据实际(ji)(ji)值(zhi)(zhi)(zhi)(zhi)与(yu)预(yu)(yu)设(she)值(zhi)(zhi)(zhi)(zhi)的(de)(de)累积(ji)误差，以(yi)一定的(de)(de)积(ji)分(fen)(fen)关(guan)系(xi)(xi)调(diao)(diao)节(jie)(jie)输出(chu)(chu)。积(ji)分(fen)(fen)作用(yong)(yong)可(ke)以(yi)消除比(bi)例(li)(li)作用(yong)(yong)无法完全(quan)消除的(de)(de)稳(wen)(wen)态误差，使系(xi)(xi)统(tong)更加稳(wen)(wen)定。微分(fen)(fen)作用(yong)(yong)（Derivative Action）：根(gen)据实际(ji)(ji)值(zhi)(zhi)(zhi)(zhi)的(de)(de)变化(hua)速率，以(yi)一定的(de)(de)微分(fen)(fen)关(guan)系(xi)(xi)调(diao)(diao)节(jie)(jie)输出(chu)(chu)。微分(fen)(fen)作用(yong)(yong)可(ke)以(yi)预(yu)(yu)测实际(ji)(ji)值(zhi)(zhi)(zhi)(zhi)的(de)(de)变化(hua)趋(qu)势，避免系(xi)(xi)统(tong)的(de)(de)过冲和震荡。河北化(hua)工PLC系(xi)(xi)统(tong)软件
