摘  要：本文介紹一種基于專(zhuān)用RDC芯片ADS1210進(jìn)行軸角解碼的旋轉(zhuǎn)變壓器接口卡。分別從旋轉(zhuǎn)變壓器原理和RDC解碼原理進(jìn)行闡明，主要描述接口卡的硬件設(shè)計(jì)和軟件功能。目前該接口卡已成功作為速度和角度編碼器，應(yīng)用于電機(jī)的速度閉環(huán)控制及收放繩纜長(zhǎng)度的計(jì)量。 關(guān)鍵詞：旋轉(zhuǎn)變壓器；AD2S1210；軸角編碼 Abstract: A rotary transformer interface card based on ADS1210 chip RDC will be introduced. On the basis of explaining the principle of resolver and the RDC decoding principle, the hardware design and the [登陸后可查看全文]
