MDX61B1320-503-4-00 只要被調(diào)量變化，輸出就變化；被調(diào)量不變化，不管靜態(tài)偏差有多大，輸出也不會變化。

上面5條推論很重要，請大家牢牢記住。記住不記住其實沒有關系，只要你能把它溶化在你的思想里也行。

溶化了么？那我出個思考題：

1、被調(diào)量回調(diào)的時候，輸出必然回調(diào)么？

2、被調(diào)量不動，設定值改變，輸出怎么辦？

3、存在單純的比例調(diào)節(jié)系統(tǒng)么？

4、純比例調(diào)節(jié)系統(tǒng)會靜差么？

第一條回答：是。

第二條回答：相當于被調(diào)量朝相反

方向改變。你想啊，調(diào)節(jié)器的輸出等于輸入偏差乘以一個系數(shù)，設定值改變就相當于設定值不變被調(diào)量突變。對吧？

第三條回答：是。在電腦出現(xiàn)之前，還沒有DCS，也沒有集中控制系統(tǒng)。為了節(jié)省空間和金錢，對于一些簡單的有自平衡能力的調(diào)節(jié)系統(tǒng)，比如水池水位，就用一個單純的比例調(diào)節(jié)系統(tǒng)完成調(diào)節(jié)。

第四條回答：否。單純的比例調(diào)節(jié)系統(tǒng)可以讓系統(tǒng)穩(wěn)定，可是他沒有辦法靜態(tài)偏差。那么怎么才能靜態(tài)偏差呢？依靠積分調(diào)節(jié)作用。
