机抖激光陀螺内在的温度特性对陀螺各方面带来的影响，制约了陀螺性能的进一步提高。为提高陀螺性能，研究了陀螺零偏的温度补偿方法。利用单温度点比较不同温度补偿模型对陀螺零偏的补偿效果，建立了零偏的温度补偿模型；研究了机抖激光陀螺零偏和多温度点的关系，根据测温点对补偿效果的影响大小，适当精简模型中两个测温点的温度数据，可将其作为冗余备用；设计了分段数据实验，验证了该模型的实用性。结果表明，多温度点补偿效果优于单温度点的补偿效果；模型简化大大减小计算量，并能满足补偿要求；利用精简后的模型补偿陀螺零偏，相比补偿前精度提高了1.6倍以上，且补偿后零偏稳定性均为10-3(°) /h量级。

The temperature characteristic of basic substances in ring laser gyro (RLG) can generate bias drift, and the long time continued manipulation of RLG increases the bias drift which will deteriorate the performance of gyroscope dramatically. Then the method for temperature compensation is investigated, and the compensating model is gained by effects with different models. The relationship between mechanically dithered RLG′s bias and multi-temperature is studied too. Based on the influence of different experimental temperature models, two temperature sensors can be simplified for the redundancies. Thus the experiment of data subsection is designed to validate the practicability of this temperature model. The result shows that multi-temperature compensation models are better than single-temperature models; the simplified multi-temperature model can reduce the computing scale, and still satisfies the requirement of real-time compensation; by using this simplified model, the compensation precision can be improved by 1.6 times at least, and the bias stability compensated are all on 10-3(°) /h level.
