DCS在控制上的大特點是依靠各種控制、運算模塊的靈活組態(tài)，可實現(xiàn)多樣化的控制策略以滿足不同情況下的需要，使得在單元組合儀表實現(xiàn)起來相當(dāng)繁瑣與復(fù)雜的命題變得簡單。隨著企業(yè)提出的高柔性、益的要求，以經(jīng)典控制理論為基礎(chǔ)的控制方案已經(jīng)不能適應(yīng)，以多變量預(yù)測控制為代表的控制策略的提出和成功應(yīng)用之后，過程控制受到了過程工業(yè)界的普遍關(guān)注。需要強調(diào)的是，廣泛應(yīng)用各種控制與優(yōu)化技術(shù)是挖掘并提升DCS綜合性能有效、直接、也是具價值的發(fā)展方向。

在實際過程控制系統(tǒng)中，基于PID控制技術(shù)的系統(tǒng)占80%以上，PID回路運用優(yōu)劣在實現(xiàn)裝置平穩(wěn)、、運行中起到舉足輕重的作用，各DCS廠商都以此作為搶占市場的有力競爭砝碼，開發(fā)出各自的PID自整定軟件。另外，根據(jù)DCS的控制功能，在基本的PID算法基礎(chǔ)上，可以開發(fā)各種改進算法，以滿足實際工業(yè)控制現(xiàn)場的各種需要，諸如帶死區(qū)的PID控制、積分分離的PID控制、微分先行的PID控制、不完全微分的PID控制、具有邏輯選擇功能的PID控制等等
