碩士 === 國立清華大學 === 動力機械工程學系 === 90 === In this thesis, the realization and verification of the multipurpose digital position converter using CPLD is presented. It represents an integrated solution in measuring the position by means of resolvers, sine/cosine optical encoders and Hall-effect sensors. The superiority of this converter is that it produces both position and velocity in digital form and the digital circuits can be easily applied to many modern applications. The external hardware required to interface between the sensors and the CPLD is limited to two A/D converters and some analog circuits. The feasibility and effectiveness of these position sensors in measuring the mechanical displacement data using the proposed digital position converter is further validated by experiments.
