In digital servo system, aimed at the characteristics of the system, the position information of rotating angle need to be measured in real time. The rotating transformer angle measuring system was designed by use of the rotating transformer and the AD2S83. Based on working principle analysis of the rotating transformer and the AD2S83, hardware circuit of the system was designed. The transformation from analog signal of the rotating angle position information into digital signal required by the system was realized. Actual measuring results showed that the operational characteristics of the rotating transformer angle measuring system are stable, and the system can meet the requirements of precision.
