摘要
在捷联惯导系统中,误差控制与补偿是影响系统精度的最重要环节和手段;结合工程实际应用,充分考虑捷联惯导系统周期性振荡的误差特性,将阻尼技术应用于捷联惯导系统误差补偿中;设计合理的阻尼回路,利用系统自身的速度信息和外界的速度信息,以消除系统的周期性振荡误差,从而提高系统的导航精度;理论分析和实验结果表明,阻尼技术可以有效地消除系统的振荡性误差,从而抑制系统误差的积累,是系统误差补偿一种有效的方法。
The error control and its compensation is a key link and method for the output precision of strapdown inertial navigation system(SINS).Airning at the engineering practical application,considering the periodic and oscillational error characteristic of SINS,the damping technique is usable in SINS error compensation.This technique designs rational damping loop and uses velocity information of the system and outside to eliminate periodic and oscillational errors of the system.Therefore,it can improve the accuracy of the system.The theoretical analysis and experiment results show the damping technique can effectively eliminate periodic and oscillational errors of the system and inhibit the accumulating errors of the system.So,it is effective error compensation method.
