| 摘 要： | 分析了温度测量误差对环形激光陀螺(RLG)零偏补偿精度的影响,通过仿真,在动态温度模型中,发现温度测量误差主要通过温度变化率对补偿结果产生影响,提出了该模型在陀螺零偏动态温度补偿中是否考虑温度测量误差的标准。仿真结果表明,对使用的温度补偿模型与温度传感器而言,在温度补偿精度明显小于0.001°/h时,要考虑温度测量误差的影响。 |

| Abstract: | The effect of temperature measuring error on the temperature compensation accuracy of RLG＇s bias is analyzed. Through simulation, the effect of temperature measuring error on compensating accuracy of bias is gained. It is found that the temperature measurement error affects the results of the compensation results primarily by temperature change rate in dynamic temperature model. The standard of considering temperature measuring error in RLG＇s dynamic temperature compensation is proposed. The simulation results show that the error of temperature should be considered when th compensa ting accuracy is less that 0. 001 °/h for temperature sensor and compensating model. |
| Keywords: | bias temperature compensation measuring error ring laser gyro |
