Abstract

In order to improve the measurement precision of on inductosyn and to reduce the impact of noise and craft of the system on the output angle data

the paper discusses the data arithmetic and implementation on the amalgamation and correction of the actual system of inductosyn. Based on the problems from zero warp of dual channels of inductosyn

the amalgamation algorithms using correction table for dealing with the leaping dot of coarse data are presented. Then a data amalgamation method is proposed for the actual system to process the variational channel numbers. It confirms the beginning dot using actual measurement data and judges the validity using four quadrants. Finally

the angle error correction method based on the piecewise linear interpolation is discussed as well. A Field Programming Gate Array(FPGA) is used to implement and verify the proposed method. Experimental results indicate that the precision of the system of inductosyn is 3" after using the two methods above. It can satisfy the system requirements for reliability

precision

stabilization

as well as strong anti-jamming.
