在提供輸入之前，變槳控制系統(tǒng)需要數(shù)據(jù)。有兩種選擇。風(fēng)速可以通過位于風(fēng)車上或附近的風(fēng)速計獨立于動力渦輪機來獲取。這些設(shè)備通常用于確定風(fēng)速是否足以啟動渦輪機。這種類型的監(jiān)督控制也可以集中用于集群或風(fēng)電場。一旦渦輪機在線（區(qū)域 2 和 3），大多數(shù)設(shè)計使用軸速作為控制輸入，因為它也可以用作系統(tǒng)設(shè)定點。

　　開環(huán)控制是設(shè)置風(fēng)車葉片間距的一種選擇。然而，這不是好的方法，因為它可能會導(dǎo)致轉(zhuǎn)子不穩(wěn)定，從而產(chǎn)生不的機械應(yīng)變。閉環(huán)控制是并且是風(fēng)電行業(yè)中常見的方法。比例積分微分 （PID） 控制器（圖 1）是工業(yè)控制系統(tǒng)的行業(yè)標準。它提供了簡單性和性能的平衡。PID 控制器將“誤差”值計算為測量過程變量和所需設(shè)定點之間的差值?？刂破髟噲D通過調(diào)整過程控制輸入來小化誤差。

　　圖 1：帶有 PID 控制器的閉環(huán)系統(tǒng)。（由愛特梅爾提供。）

　　PID控制算法允許系統(tǒng)根據(jù)測量信號的歷史和變化率做出響應(yīng)，從而使系統(tǒng)準確穩(wěn)定。對于槳距控制和電機控制等系統(tǒng)，通常會忽略導(dǎo)數(shù)項 （D），因為它易受噪聲影響。這給我們留下了一個 PI 控制器。

　　作為開發(fā) PI 控制器的起點，Atmel 提供了完整的文檔和 C 中離散 PID 控制器（例如AVR221）的工作實現(xiàn)。1 AVR221 代碼適用于任何 Atmel AVR 設(shè)備，從 8 位到 32 位微控制器。在操作中，PID 控制器獲取測量的輸入，在本例中為軸速度，并將其從期望值中減去以提供誤差值。該算法（圖 2）通過比例項處理當前誤差，通過整數(shù)項處理過去值，并使用導(dǎo)數(shù)項預(yù)測未來值。如前所述，電動機和發(fā)電機控制系統(tǒng)通常選擇通過將微分系數(shù)設(shè)置為零來預(yù)測能力。
