【摘要】 通过对闭环干涉式光纤陀螺 ( IFOG)原理的分析 ,修正了以往闭环 IFOG输入、输出的表达式。指出在角加速度存在的情况下 ,光功率的波动产生 IFOG输出误差 ,通过仿真验证了所提出的观点。最后得出结论 ,研制高精度并能适用于剧烈运动状态的 IFOG时 ,必须考虑到角加速度这个因素 ,并补偿由其引起的输出误差更多还原

【Abstract】 This paper modifies the formula which formulates the input and output of the closed-loop Interferometer Fiber Optic Gyroscopes(IFOG) by analysing IFOG theory.We verifies the opinion through our simulating that the fluctuation of optical power make output errors of the IFOG on the condition that the angular acceleration is being.Finally,draw a conclusion must take angular acceleration into account and compensate for the output errors when we study the high precise IFOG applied to the violent motion conditions.更多还原
