【摘要】 为了减小温度变化对动力调谐陀螺仪性能稳定性的影响,设计了温度补偿方案。利用控温箱,有计划地改变陀螺仪工作温度,实验测得各温度下陀螺仪的漂移,建立陀螺仪输出的温度模型,通过测温元件,实测该时刻的陀螺仪温度值,估计出陀螺仪当前温度下的漂移输出值,从陀螺仪实测的输出值中将估计出的漂移值扣除,即为陀螺仪补偿后的输出。仿真表明:在26℃～50℃温度范围内,温度补偿后的陀螺仪漂移输出小于0.050/h,满足设计指标要求。可见,此温度补偿方案能有效减小陀螺仪温度漂移。更多还原

【Abstract】 To minish the effect of temperature change to the stability of DTG,the temperature expiation project was designed.To change the temperature of DTG designedly,test the temperature drift of DTG on some temperatures,build the temperature drift model of DTG’s output.Test the temperature of DTG at this moment by temperature-test component and estimate the drift output of DTG by using the temperature model,the DTG’s output after temperature expiation can be counted by subtracting the temperature excursion output from the tested output of DTG.The results of emulate show that in the temperature range from 26℃ to 50℃,output of DTG after expiation is below 0.05°/h,which satisfy the requirement of design index,so this project can minish temperature excursion of DTG effective.更多还原
