Philips PM5514V

電梯轎廂升降的閉環控制,在電梯提升的主機上已經裝有編碼器(例如德國海德漢的ERN1387),提供增量的A、B正餘弦信號,每周2048個脈衝周期,同時提供單圈一個周期的C、D正餘弦信號,單圈的C、D正餘弦信號經過粗糙的位置分割,可以提供電機UVW的換相信息;而每周2048個周期的正餘弦信號,經過更進一步的細分,可獲得高分辨率的位置變化,這種高分辨率的位置變化信息主要用於很短時間的加速度計算,因為在時間變量很小的情況下需要準確的加速度反饋,就需要有較多的位置變化信息,這就需要編碼器的分辨率非常高,並且位置精度準確,這樣可以保證獲得加速度反饋,以控制電機輸入電流。

但是由於電梯機械係統上的機械誤差,電梯在每層停止時仍然需要由外部的平層傳感器反饋,才能獲得準確定位,例如用平層光電開關,或者直接再用平層值多圈編碼器,才能構成一個位置準確的閉環伺服係統。

實際上伺服係統需要的編碼器可能有兩個(或者只用一個),一個是在電機上高速端,針對電機的換相與加速度反饋,這個反饋進入電機驅動器,決定電機的控制電流的換相與大小(力矩環),另一個是用於位置終端低速端的準確定位。在電機端的編碼器需要高分辨率,常用高分辨率增量編碼器,以獲得加速度的變化量;而在運動終端的編碼器需要位置上的準確與可靠,常用值多圈編碼器(也有用直線光柵尺)。如果只用一個編碼器(例如只用電機端編碼器),那就需要在位置上依賴機械傳動部分的,而目前的機械傳動幾乎都掌握在日係和德係廠家手中,由他們壟斷。在終端加裝傳感器(編碼器),是避開這種壟斷的一種辦法。

在變頻器控制係統中,由於不需要電機換相信號,編碼器也就可以直接就裝在了運動終端,也稱為低速端。
