The design of the two-speed resolve to digital converter with coarse-fine combination

Abstract: According to the multi-polar resolver to digital converter's combination of coarse-fine axis angle and its error correction, this paper presented a two-speed resolve to digital converter with coarse-fine combination. Based on RD-19230 and CPLD, the two-speed resolve to digital converter is equipped to finish the coarse-fine data transformation, combination and correction, which meets the two-speed resolve to digital converter's requirements of high accuracy and miniaturization.
