摘　　要：为了缩短光纤惯测组合的稳定时间,保证输出精度,通常采取温度补偿的措施.通过对光纤陀螺、石英加速度计和转换电路受温度影响的机理进行分析,对多种补偿方式和误差模型的优缺点进行比较,确定了硬件补偿和软件补偿相结合的方案.同时,对温度补偿试验方法进行研究,模拟真实工作温度环境,提高试验效率和准确性,减小了测量误差.经试验验证,温补效果显著,可以应用于中精度惯导领域.In order to shorten the stability time of FOG IMU, and ensure its accuracy, the temperature compensation usual- ly could be used. Through the mechanism analysis of temperature effect on FOG, quartz Accelerometer and I/F electric cir- cuit, and comparing the advantages and disadvantages of compensation measures and error models, the method of combining hardware compensation and software compensation is decided to adopt. Besides, by researching the experimental methods of temperature compensation, and simulating operating temperature environment, we can improve the efficient and accuracy of experiment. The resuhs show that the method is effective to compensate the temperature drift error of the accelerator, and this temperature compensation can be applied to the field of medium precision INS.
