Automatic amplitude modulation method, system and medium applied to inductive synchronizer

Abstract

The invention provides an automatic amplitude modulation method, system and medium applied to an induction synchronizer, including: data sampling and segmentation steps: sampling the amplified outputs of the sin and cos terminals of the induction synchronizer respectively to obtain sampling data at the sin terminal According to the frequency and sampling frequency of the excitation signal, segment the sampling data at the sin end and the sampling data at the cos end respectively; the amplitude modulation step of the inductive synchronizer: calculate the sum of squares for each segment according to each segment of data after segmentation , to obtain a new N×2 sequence, N is the preset value, according to this N×2 sequence, estimate the magnification of the sin and cos terminals, and dynamically adjust the magnification of the sin and cos terminals to make the two amplitudes consistent , to improve the acquisition accuracy of the inductosynchronizer. The invention realizes the dynamic adjustment of the amplitude of the output end of the inductive synchronizer, reduces the complexity of system design and debugging, and realizes the intellectualization and generalization of the amplitude adjustment.

Description

Technical field[0001]The present invention relates to the field of automatic control and measurement, and in particular, to an automatic modulation method, system, and medium applied to an induction synchronizer.Background technique[0002]As spacecraft has become more and more, and the increase in activity components on the spacecraft increases, the accuracy and reliability of the angular elements are also increasingly high, and the measurement of the round gratings and encoders are measured. The angle component has gradually been replaced by the induction synchronizer due to its difficulty to ensure that the long life and high reliability are in some applications.[0003]The operating principle of the induction synchronizer determines its amplitude of the two-phase input SIN, COS, generally adjusts the preamplifier circuit, but use this method requires precision resistance, capacitance match, adjustment cycle, and dynamic adjustment Poor performance, all need to be adjusted separately...

Problems solved by technology

[0003] The working principle of the inductive synchronizer determines that it is very sensitive to the amplitudes of sin and cos at the two-phase input terminals. Generally, a preamplifier circuit is used for adjustment, but this method requires precise resistance and capacitance matching, a long adjustment period, and dynamic adjustment Poor performance, each inductive synchronizer needs to be adjusted separately, and cannot be generalized
