High-precision rotary transformer signal generation method

Abstract

The invention belongs to the technical field of measurement and control, and relates to a high-precision rotary transformer signal generation method. A high-precision rotary transformer signal is implemented by a universal instrument dual-channel function generator and a high-precision digital multimeter. One channel of the dual-channel function generator generates a signal meeting the sinusoidalcomponent of the rotary transformer, and the other channel of the dual-channel function generator generates a signal meeting the cosine component of the rotary transformer. The signal phase differencebetween the two channels is zero. The digital multimeter is used for adjusting the output amplitude precision. The signal parameter range is wide, and the signal generated by using the physical rotary transformer usually only has single excitation voltage and frequency. Compared with the conventional physical generation method, the voltage range and the frequency range can be greatly extended byusing wide range setting of the dual-channel function generator, and multiple output voltage and frequency can be flexibly set. The method is simple and efficient and can be used for rotary transformer angle measurement equipment debugging, system simulation and equipment measurement calibration.
