摘要
光电稳定平台中的陀螺装调误差影响平台角速度的测量精度。研究了速率陀螺稳定平台角速度的计算方法,重点是陀螺敏感轴交叉耦合情况下平台角速度的计算。得到了稳定平台角速度的理论计算公式,在此基础上,得到了理想情况和陀螺敏感轴交叉耦合情况下的测量计算公式。仿真和试验表明,对陀螺敏感轴的交叉耦合进行补偿,可以有效改善视线角速度的测量精度。
Fixing and adjustment errors of gyros in the photoelectronic stabilized platform impact the measuring accuracy of angular rate of the platform.The calculation method of the angular rate of the gyro stabilization platform is systematically studied in this paper.The emphasis is the calculation for the angular rate of the platform with cross coupling of sensitive axes of gyros.The theoretical calculation formula of the angular rate of the stabilized platform is obtained.On this base,calculation formula are obtained under an ideal condition and under the condition of the cross coupling of sensitive axes of gyros respectively.It is shown by simulations and experiments that the compensation for the cross coupling of sensitive axes of gyros can effectively improve the measuring accuracy of line-of-sight（LOS） rate.
