В присутствии внешнего вибрационного ускорения, действующего на лазерный блок лазерного гироскопа (ЛГ), из-за ограниченной поперечной жесткости привода виброподставки возникает его смещение. В данной статье предложен новый метод компенсации динамической погрешности БИНС на ЛГ в условиях вибрации. Разработана модель смещений блока ЛГ при ускорениях. Выведена модель эквивалентного дрейфа гироскопа в условиях вращения и ускорения, которая позволяет описать динамическую погрешность. Проведены эксперименты по оптимизации колебаний с целью оценки неизвестных параметров. Результаты экспериментов в условиях вибрации подтверждают эффективность предложенного метода.

The dither axis bending occurs in the presence of input acceleration acting on the laser block of the ring laser gyro (RLG) due to the limited transverse stiffness of the dither motor, which will cause g-sensitive misalignments under vibration environments. A novel RLG SINS dynamic error compensation method is proposed under vibration environments in this paper. G-sensitive misalignment model of the RLG unit is developed. The equivalent gyro drift model under rotation and acceleration environments is deduced to describe the dynamic error. Optimized vibration experiments are conducted to estimate the unknown parameters. Vibration experiment results prove the validity of this method.
