Research on Modeling and Compensation Technology for Temperature Errors of FOG
Jing Jin · Journal of Astronautics · 2006
In this paper,the issue of temperature compensation for fiber optic gyroscope(FOG) is studied.The main factors causing the temperature bias changing of FOG was analyzed.Based on the artificial neutral net(ANN) and statistics,a temperature compensation modeling for FOG was established.It was trained by data from many temperature experiments on one kind of FOG,included experiments at the constant temperature and dynamic temperature of 0～50℃.Finally,the designed modeling was used to compensate the bias of FOG.The experimental results show that this method can enhance bias stability of FOG effectively.
