　功率放大器（可以從單個電源開關(guān)到由 6 個功率晶體管制成的三相逆變器）。

　　每個感測變量的反饋：在電機控制系統(tǒng)中，基本的反饋是速度（或位置，可以從中獲得速度）。速度/位置傳感器有多種形式。在 BLDC 系統(tǒng)中，典型的傳感器是霍爾效應(yīng)傳感器，每個相位一個，這些傳感器用于確定轉(zhuǎn)子何時移動了一步，移動發(fā)生的時間段用于確定電機的速度。進(jìn)入電機的電流是另一個重要變量，在 DC 和 BLDC 電機中，電流與電機扭矩直接相關(guān)，在正弦電機中，它也與扭矩有關(guān)，但不是線性關(guān)系。在這些電機中，它也是一種重要的反饋方法，在磁場定向控制 （FOC） 技術(shù)中，它是一個基本變量。請注意，有一些方法可以在沒有傳感器的情況下估計轉(zhuǎn)子的位置，

　　速度和電流（扭矩）參考：這是定義預(yù)期輸出的用戶或系統(tǒng)輸入。這些可以是 HMI 中用戶的直接設(shè)置，也可以是來自另一臺計算機或系統(tǒng)通過串行通信鏈路的自動控制。

　　速度和電流控制器：在基于 MCU 的電機控制中，這些模塊通常由軟件組成。 DSP 控制器和帶有 DSP 協(xié)處理器的 MCU（例如 Kinetis MCU 中的 ARM? CortexTM-M4 內(nèi)核）可以幫助進(jìn)行執(zhí)行控制功能所需的數(shù)學(xué)計算。電機系統(tǒng)中典型的控制形式是 PI（比例 - 積分）。通常不使用 PID 控制器，因為 D 項（導(dǎo)數(shù)）會使系統(tǒng)容易受到高頻噪聲的影響。D 項的優(yōu)點是提高對輸入快速變化的響應(yīng)，因為電機是緩慢的機械過程（與其他可控變量相反），并且電機緩慢啟動以避免電流峰值，適應(yīng)快速變化的優(yōu)勢確實沒有幫助。
