Иерархические тепловые модели бесплатформенной инерциальной навигационной системы на волоконно-оптических гироскопах

Abstract

Hierarchical thermal models of strapdown inertial navigation system with fiber-optical gyros and accelerometers, fig.1-4, 7-9, tabl.1 are constructed and researched. Models of thermal drift of gyros and accelerometers on experimental output signals are constructed and identified. Approaches to minimization and algorithmic com-pensation of thermal drift, fig. 5, 6, 10, formulas (1)-(5) are developed. Temperature calibration on signals of thermal sensors on the basis of the constructed mathematical models thermal compensation is conducted, minimization of drift of gyros, fig. 11, 12 formulas (6) - (8), tabl.2 is realized.
