【摘要】：为了研究单轴旋转惯导系统的高度通道误差抑制方法,首先分析了纯惯导高度通道的稳定性,并通过比力方程建立了误差模型。然后推导了单轴旋转惯导系统的高度通道误差方程,分析了抑制高度通道误差发散的条件,得出在旋转轴处于水平状态时可以极大地抑制高度通道误差的结论。最后,在三轴加速度计存在零偏的情况下,对惯导系统的高度通道误差进行仿真。理论分析与仿真结果均表明旋转轴处于水平状态时可以有效抑制高度通道误差。
[Abstract]:In order to study the altitude channel error suppression method of the single axis rotating inertial navigation system, the stability of the pure inertial navigation altitude channel is first analyzed, and the error model is established by the specific force equation. Then, the altitude channel error equation of the single axis rotating inertial navigation system is derived, and the conditions for suppressing the divergence of height channel error are analyzed. The conclusion is drawn that the height channel error can be greatly suppressed when the rotation axis is in a horizontal state. Finally, the altitude channel error of inertial navigation system is simulated under the condition of zero bias of triaxial accelerometer. The theoretical analysis and simulation results show that the height channel error can be effectively suppressed when the rotating axis is in a horizontal state.
