Abstract

The invention provides an inductosyn angle measurement error analysis and compensation method and belongs to the technical field of detection. The method comprises: using a high-precision single-axistest rotary table as an angle measurement reference and using the least squares identification method to analyze respective harmonics of the angle measurement of the inductosyn; making targeted hardware adjustment according to an analysis result; acquiring error data again as a compensation sampling point, and using the linear interpolation method to compensate the angle measurement error software. The method solves the problems that the existing inductosyn analysis and compensation method is incomprehensive in analysis, unsatisfactory in compensation effect, limited in the number of samplingpoints, low in efficiency, and difficult in model creation.

Description

technical field

[0001] The invention relates to an angle measurement error analysis and compensation method of an inductive synchronizer, which belongs to the technical field of detection. Background technique

[0002] The paper "Separation Technology of Angle Measurement Error of Circular Induction Synchronizer" (Proceedings of the Chinese Society for Electrical Engineering, Ren Shunqing, 200104) analyzed the composition of the angle measurement error of the circular induction synchro In the actual test of the angle error, the separation method of the long-period first harmonic, short-period first harmonic and second harmonic for the angle measurement error of the inductive synchronizer is proposed, and the corresponding software and hardware compensation technology is adopted to improve the induction synchronization. angle measurement accuracy. Its disadvantages are: although the error separation technology proposed based on the mechanism of the measurement error of the i...
