PLC系(xi)(xi)(xi)统(tong)中的(de)PID控(kong)(kong)制器（Proportional-Integral-Derivative Controller）是一种常用(yong)(yong)的(de)控(kong)(kong)制算法，用(yong)(yong)于自(zi)动调节系(xi)(xi)(xi)统(tong)的(de)输(shu)出(chu)，以(yi)(yi)使系(xi)(xi)(xi)统(tong)的(de)实际(ji)值(zhi)(zhi)(zhi)(zhi)接近预设(she)值(zhi)(zhi)(zhi)(zhi)。PID控(kong)(kong)制器的(de)作(zuo)(zuo)用(yong)(yong)主要有以(yi)(yi)下几个方面：比例(li)作(zuo)(zuo)用(yong)(yong)（Proportional Action）：根(gen)(gen)据实际(ji)值(zhi)(zhi)(zhi)(zhi)与预设(she)值(zhi)(zhi)(zhi)(zhi)之间的(de)差异，以(yi)(yi)一定(ding)的(de)比例(li)关(guan)(guan)系(xi)(xi)(xi)调节输(shu)出(chu)。当实际(ji)值(zhi)(zhi)(zhi)(zhi)偏离(li)预设(she)值(zhi)(zhi)(zhi)(zhi)较大时，比例(li)作(zuo)(zuo)用(yong)(yong)会快速调整(zheng)输(shu)出(chu)，以(yi)(yi)尽(jin)快将实际(ji)值(zhi)(zhi)(zhi)(zhi)接近预设(she)值(zhi)(zhi)(zhi)(zhi)。积分(fen)(fen)作(zuo)(zuo)用(yong)(yong)（Integral Action）：根(gen)(gen)据实际(ji)值(zhi)(zhi)(zhi)(zhi)与预设(she)值(zhi)(zhi)(zhi)(zhi)的(de)累积误差，以(yi)(yi)一定(ding)的(de)积分(fen)(fen)关(guan)(guan)系(xi)(xi)(xi)调节输(shu)出(chu)。积分(fen)(fen)作(zuo)(zuo)用(yong)(yong)可以(yi)(yi)消除比例(li)作(zuo)(zuo)用(yong)(yong)无法完全消除的(de)稳(wen)态误差，使系(xi)(xi)(xi)统(tong)更加稳(wen)定(ding)。微(wei)分(fen)(fen)作(zuo)(zuo)用(yong)(yong)（Derivative Action）：根(gen)(gen)据实际(ji)值(zhi)(zhi)(zhi)(zhi)的(de)变化速率，以(yi)(yi)一定(ding)的(de)微(wei)分(fen)(fen)关(guan)(guan)系(xi)(xi)(xi)调节输(shu)出(chu)。微(wei)分(fen)(fen)作(zuo)(zuo)用(yong)(yong)可以(yi)(yi)预测实际(ji)值(zhi)(zhi)(zhi)(zhi)的(de)变化趋(qu)势，避免系(xi)(xi)(xi)统(tong)的(de)过冲和震(zhen)荡(dang)。
