style="text-indent:25px">一種高精度角度編碼器轉(zhuǎn)角精度檢測方法的誤差分析：針對高精度角度編碼器轉(zhuǎn)角精度的檢測，提出了一種基于雙頻激光干涉儀的光電編碼器轉(zhuǎn)角精度檢測方法，并研制了相應(yīng)的檢測裝置.該裝置以步進電機為驅(qū)動元件，通過減速機構(gòu)帶動被檢編碼器和角度基準(zhǔn)旋轉(zhuǎn)，以Renishaw雙頻激光干涉儀為角度基準(zhǔn)檢測儀器，使用RenishawRX10回轉(zhuǎn)軸校準(zhǔn)組件為角度旋轉(zhuǎn)基準(zhǔn)，檢測精度達1.36″.分別使用該裝置和傳統(tǒng)手動檢測裝置對21bit***式編碼器進行精度檢測對比實驗，結(jié)果表明，該裝置是可行的，且在檢測效率，檢測精度上均高于傳統(tǒng)檢測裝置.</p><p style="text-indent:25px">高精度角度編碼器工作原理：由一個中心有軸的光電碼盤，其上有環(huán)形通、暗的刻線，有光電發(fā)射和接收設(shè)備件讀取，獲得四組正弦波信號組合成A、B、C、D，每個正弦波相差90度相位差（相對于一個周波為360度），將C、D信號反向，疊加在A、B兩相上，可增強穩(wěn)定信號；另每轉(zhuǎn)輸出一個Z相脈沖以標(biāo)志零位參考位。由于A、B兩相相差90度，可通過比較A相在前還是B相在前，以判別編碼器的正轉(zhuǎn)與反轉(zhuǎn)，通過零位脈沖，可獲得編碼器的零位參考位。編碼器碼盤的材料有玻璃、金屬、塑料，玻璃碼盤是在玻璃上沉積很薄的刻線，其熱穩(wěn)定性好，精度高，金屬碼盤直接以通和不通刻線，不易碎，但由于金屬有一定的厚度，精度就有限制，其熱穩(wěn)定性就要比玻璃的差一個數(shù)量級，塑料碼盤是經(jīng)濟型的，其成本低，但精度、熱穩(wěn)定性、壽命均要差一些。分辨率—編碼器以每旋轉(zhuǎn)360度提供多少的通或暗刻線稱為分辨率，也稱解析分度、或直接稱多少線，一般在每轉(zhuǎn)分度5~10000線。高精度角度編碼器單圈的只能反饋單圈也就是360°范圍內(nèi)的位置編碼。</p><div

style="text-indent:25px">模擬測速電機的相關(guān)噪聲問題的處理：在系統(tǒng)沒有運行時的測速電機的反饋信號，存在不規(guī)律的數(shù)值波動，由于速度調(diào)節(jié)器采用的時PI控制，是無差系統(tǒng)，在零速給定的情況下，反饋信號在“0”附件的變化造成系統(tǒng)無法正常停車，出現(xiàn)抖動情況。問題的解決：對于疊加到模擬信號的背景噪聲，以及模擬電路中的漂移信號等，一般是高頻噪聲，可通過軟件或硬件濾波方式進行處理；對于信號電纜應(yīng)該選用雙絞屏蔽電纜，并且電纜屏蔽層要兩端可靠接地；但是需要注意的時，雙端接地對于低頻的噪聲串?dāng)_，將會在信號中疊加低頻“hum”接地環(huán)流噪聲，一方面在驅(qū)動側(cè)將屏蔽層可靠接地，現(xiàn)場端可通過MKT型電容器（容量10nF/100V）可靠接地。高精度角度編碼器在永磁同步電機位置測量中的應(yīng)用有哪些？寧夏小角度編碼器</p><p

style="text-indent:25px">在軟件方面，也可通過速度調(diào)節(jié)器的PIP控制的切換等方法解決相關(guān)問題。我們可以看到在解決有關(guān)高精度角度編碼器的干擾問題時，應(yīng)該從系統(tǒng)設(shè)計入手，根據(jù)實際現(xiàn)場的應(yīng)用與環(huán)境條件選擇合適的設(shè)備，高精度角度編碼器系統(tǒng)一般受到共模和差模干擾，對于共模干擾來講我們可選擇差分類型的高精度角度編碼器，比如雙極性類型，對于差模干擾，一般對于電纜選擇，線路路徑，電源系統(tǒng)隔離處理，信號參考等需要仔細設(shè)計與布置。由于問題的復(fù)雜性，分析與處理方法可能會有不同和不足，對于實際問題的分析，希望能拋磚引玉，深入討論，以利進一步處理實際工程問題。高精度絕對值角度編碼器哪里有賣</p></p><br
