AI Overview
Fiber optic gyro (FOG) error modeling in a factory setting
focuses on compensating for
temperature-dependent scale factor errors
and bias drift to ensure high-accuracy performance
. Key techniques include
hyperbolic curve fitting for scale factor calibration
over full temperature ranges,
using FEA (Finite Element Method) to manage thermal deformation errors
, and employing automated winding, which causes structural variations that require individual sensor calibration.
Key Aspects of FOG Error Modeling
-
Drift Faults:
Modeled with parameters like the coefficient of drift (
) to handle increasing constant terms over time.
- Multiplicative Faults: Modeled using a multiplier factor ($k_3$) to correct for drastic changes in the scale factor caused by environmental conditions.
- Periodic Interference: Addressed by identifying and filtering out periodic signals that appear in the output.
