PCS系統(tǒng)完成對工藝過程的監(jiān)測和控制，工藝過程的主要參數(shù)為溫度、壓力、流量、液位、界面、密度、含水、轉(zhuǎn)速、震動等的監(jiān)測控制和報警，常用的控制為PID控制，包括分程和串級等。PCS系統(tǒng)的核心是RS3控制系統(tǒng)，它是Rosemount 公司在70年代中期推出的DCS系統(tǒng)，經(jīng)過多次的升級和改進，具有很好的穩(wěn)定性和擴展性，功能完善，使用靈活等特點。RS3提供標(biāo)準(zhǔn)的PID模塊，可方便的組態(tài)PID控制功能，同時RS3系統(tǒng)的CB（Control Block）模塊提供方便連接功能，可以將各種基本的功能塊組合成復(fù)雜的控制方案。為保證過程控制的無擾動切換,對單回路，由自動狀態(tài)切換至手動狀態(tài)時設(shè)定值（SP）值跟蹤過程值（PV）值；對串級回路，主回路鎖定在自動模式，如果副回路不在遠(yuǎn)程模式（remote），則主回路的輸出跟蹤副回路的設(shè)定值，如果副回路在手動模式，則副回路的設(shè)定值跟蹤過程值（PV）值。
  下圖所示為兩列同軸的兩級壓縮機的級聯(lián)、負(fù)荷分配及進出口壓力控制方案，兩列壓縮機可同時工作，也可單列工作，前后兩級的入口壓力變化與出口壓力變化的比較結(jié)果控制壓縮機的轉(zhuǎn)速，保證壓縮機的負(fù)荷平衡和平穩(wěn)運行。

如圖：
① 低壓（一級）入口的壓力由分程控制PIC-5131控制，其設(shè)定值由操作員設(shè)定。
② PIC-5131的輸出同為FIC-5134和FIC-5135的遠(yuǎn)方設(shè)定值。如果一列壓縮機不運行，則該列信號不影響壓力控制，壓力控制由運行列完成。
③ PIC-5131的參數(shù)應(yīng)當(dāng)在兩列同時運行時整定，當(dāng)為一列運行時，相應(yīng)的控制響應(yīng)將會較兩列同時運行為慢，可確保控制效果的穩(wěn)定。
④ 高壓（二級）入口的壓力由分程控制PIC-5252控制，其設(shè)定值由操作員設(shè)定。
⑤ PIC-5252的輸出同為FIC-5255和FIC-5256的遠(yuǎn)方設(shè)定值。如果一列壓縮機不運行，則該列信號不影響壓力控制，壓力控制由運行列完成。
⑥ PIC-5252的參數(shù)應(yīng)當(dāng)在兩列同時運行時整定，當(dāng)為一列運行時，相應(yīng)的控制響應(yīng)將會較兩列同時運行為慢，可確保控制效果的穩(wěn)定。
