在工程實(shí)際中，應(yīng)用為廣泛的調(diào)節(jié)器控制規(guī)律為比例、積分、微分控制，簡稱PID控制，又稱PID調(diào)節(jié)。PID控制器問世至今已有近70年歷史，它以其結(jié)構(gòu)簡單、穩(wěn)定性好、工作可靠、調(diào)整方便而成為工業(yè)控制的主要技術(shù)之一。當(dāng)被控對(duì)象的結(jié)構(gòu)和參數(shù)不能完全掌握，或得不到的數(shù)學(xué)模型時(shí)，控制理論的其它技術(shù)難以采用時(shí)，系統(tǒng)控制器的結(jié)構(gòu)和參數(shù)依靠經(jīng)驗(yàn)和現(xiàn)場(chǎng)調(diào)試來確定，這時(shí)應(yīng)用PID控制技術(shù)為方便。即當(dāng)我們不完全了解一個(gè)系統(tǒng)和被控對(duì)象﹐或不能通過有效的測(cè)量手段來獲得系統(tǒng)參數(shù)時(shí)，適合用PID控制技術(shù)。PID控制，實(shí)際中也有PI和PD控制。PID控制器就是根據(jù)系統(tǒng)的誤差，利用比例、積分、微分計(jì)算出控制量進(jìn)行控制的。 

　　比例（P）控制 

　　比例控制是一種簡單的控制方式。其控制器的輸出與輸入誤差信號(hào)成比例關(guān)系。當(dāng)僅有比例控制時(shí)系統(tǒng)輸出存在穩(wěn)態(tài)誤差（Steady-state error）。 

　　積分（I）控制 

　　在積分控制中，控制器的輸出與輸入誤差信號(hào)的積分成正比關(guān)系。對(duì)一個(gè)自動(dòng)控制系統(tǒng)，如果在進(jìn)入穩(wěn)態(tài)后存在穩(wěn)態(tài)誤差，則稱這個(gè)控制系統(tǒng)是有穩(wěn)態(tài)誤差的或簡稱有差系統(tǒng)（System with Steady-state Error）。為了穩(wěn)態(tài)誤差，在控制器中引入“積分項(xiàng)”。積分項(xiàng)對(duì)誤差取決于時(shí)間的積分，隨著時(shí)間的增加，積分項(xiàng)會(huì)增大。這樣，即便誤差很小，積分項(xiàng)也會(huì)隨著時(shí)間的增加而加大，它推動(dòng)控制器的輸出增大使穩(wěn)態(tài)誤差進(jìn)一步減小，直到等于零。因此，比例 積分(PI)控制器，可以使系統(tǒng)在進(jìn)入穩(wěn)態(tài)后無穩(wěn)態(tài)誤差。 

　　微分（D）控制 

　　在微分控制中，控制器的輸出與輸入誤差信號(hào)的微分（即誤差的變化率）成正比關(guān)系。 自動(dòng)控制系統(tǒng)在克服誤差的調(diào)節(jié)過程中可能會(huì)出現(xiàn)振蕩甚至失穩(wěn)。其原因是由于存在有較大慣性組件（環(huán)節(jié)）或有滯后(delay)組件，具有抑制誤差的作用，其變化總是落后于誤差的變化。解決的辦法是使抑制誤差的作用的變化“超前”，即在誤差接近零時(shí)，抑制誤差的作用就應(yīng)該是零。這就是說，在控制器中僅引入“比例”項(xiàng)往往是不夠的，比例項(xiàng)的作用僅是放大誤差的幅值，而目前需要增加的是“微分項(xiàng)”，它能預(yù)測(cè)誤差變化的趨勢(shì)，這樣，具有比例 微分的控制器，就能夠提前使抑制誤差的控制作用等于零，甚至為負(fù)值，從而避免了被控量的嚴(yán)重超調(diào)。所以對(duì)有較大慣性或滯后的被控對(duì)象，比例 微分(PD)控制器能改善系統(tǒng)在調(diào)節(jié)過程中的動(dòng)態(tài)特性。 

   在PID參數(shù)進(jìn)行整定時(shí)如果能夠有理論的方法確定PID參數(shù)當(dāng)然是理想的方法，但是在實(shí)際的應(yīng)用中，更多的是通過湊試法來確定PID的參數(shù)。 

   增大比例系數(shù)P一般將加快系統(tǒng)的響應(yīng)，在有靜差的情況下有利于減小靜差，但是過大的比例系數(shù)會(huì)使系統(tǒng)有比較大的超調(diào)，并產(chǎn)生振蕩，使穩(wěn)定性變壞。 

   增大積分時(shí)間I有利于減小超調(diào)，減小振蕩，使系統(tǒng)的穩(wěn)定性增加，但是系統(tǒng)靜差時(shí)間變長。 

   增大微分時(shí)間D有利于加快系統(tǒng)的響應(yīng)速度，使系統(tǒng)超調(diào)量減小，穩(wěn)定性增加，但系統(tǒng)對(duì)擾動(dòng)的抑制能力減弱。 

   在湊試時(shí)，可參考以上參數(shù)對(duì)系統(tǒng)控制過程的影響趨勢(shì)，對(duì)參數(shù)調(diào)整實(shí)行先比例、后積分，再微分的整定步驟。 

   首先整定比例部分。將比例參數(shù)由小變大，并觀察相應(yīng)的系統(tǒng)響應(yīng)，直至得到反應(yīng)快、超調(diào)小的響應(yīng)曲線。如果系統(tǒng)沒有靜差或靜差已經(jīng)小到允許范圍內(nèi)，并且對(duì)響應(yīng)曲線已經(jīng)滿意，則只需要比例調(diào)節(jié)器即可。 

   如果在比例調(diào)節(jié)的基礎(chǔ)上系統(tǒng)的靜差不能滿足設(shè)計(jì)要求，則加入積分環(huán)節(jié)。在整定時(shí)先將積分時(shí)間設(shè)定到一個(gè)比較大的值，然后將已經(jīng)調(diào)節(jié)好的比例系數(shù)略為縮小，然后減小積分時(shí)間，使得系統(tǒng)在保持良好動(dòng)態(tài)性能的情況下，靜差得到。在此過程中，可根據(jù)系統(tǒng)的響應(yīng)曲線的好壞反復(fù)改變比例系數(shù)和積分時(shí)間，以期得到滿意的控制過程和整定參數(shù)。 

   如果在上述調(diào)整過程中對(duì)系統(tǒng)的動(dòng)態(tài)過程反復(fù)調(diào)整還不能得到滿意的結(jié)果，則可以加入微分環(huán)節(jié)。首先把微分時(shí)間D設(shè)置為0，在上述基礎(chǔ)上逐漸增加微分時(shí)間，同時(shí)相應(yīng)的改變比例系數(shù)和積分時(shí)間，逐步湊試，直至得到滿意的調(diào)節(jié)效果。
