【摘要】：為了研究單軸旋轉(zhuǎn)慣導(dǎo)系統(tǒng)的高度通道誤差抑制方法,首先分析了純慣導(dǎo)高度通道的穩(wěn)定性,并通過比力方程建立了誤差模型。然后推導(dǎo)了單軸旋轉(zhuǎn)慣導(dǎo)系統(tǒng)的高度通道誤差方程,分析了抑制高度通道誤差發(fā)散的條件,得出在旋轉(zhuǎn)軸處于水平狀態(tài)時可以極大地抑制高度通道誤差的結(jié)論。最后,在三軸加速度計存在零偏的情況下,對慣導(dǎo)系統(tǒng)的高度通道誤差進(jìn)行仿真。理論分析與仿真結(jié)果均表明旋轉(zhuǎn)軸處于水平狀態(tài)時可以有效抑制高度通道誤差。
[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.
