摘要

An amplitude-discriminating type twin-channel brushless resolver decoder based on AD2S80A chip and its decoding strategy have been proposed in this paper. The decoder uses two AD2S80A chips as resolver-to-digital converter(RDC). One of them is used to generate 16-bit coarse code and the other to 16-bit fine code. Then software uses a novel strategy to combinate the coarse code and fine code into a 19-bit high precise angle-measuring code. Finally, an experiment has verified the strategy which is practical for high precise angle position sensing.
