Other AbstractThe present invention relates to a rotary transformer decoding method which comprises a step of collecting the sine signal and the cosine signal outputted by a rotary transformer and the input excitation signal of the rotary transformer by a signal collection module, a step of orderly carrying out averaging processing, per-unit processing and integer processing on the collected signals orderly, a step of carrying out interval judgment on the data which is subjected to integer processing, and a step of carrying out the vector mode of CORDIC iterative processing on the data which is subjected to the integer processing, obtaining sin theta and cos theta values, and then carrying out interval substitution to obtain actual sin theta and cos theta values. According to the method, the software decoding of rotary transformer output signals is realized, a special decoding novel product and related peripheral circuits are saved, the cost is saved, the complexity of a circuit is reduced, the precision is high, and the cost of a servo control system can be reduced.
