To reduce and compensate the influence of temperature on ring laser gyro bias error and attain the precision of inertial level gyro, the mechanism of RLG zero-bias error due to temperature is analyzed. Based on a great number of environmental temperature experiments of RLG, a general temperature compensating model and a new kind of BP neural network model are established. A method for identifying the model parameter is proposed. Simulation results show that the simplified compensating model can reduce the zero-bias by more than a magnitude and achieve real-time compensating feature.

零偏是衡量激光陀螺性能的一个重要指标，但其受温度影响很大，为了降低和补偿温度对激光陀螺零偏的影响，使其达到惯性级陀螺仪的精度要求，分析了温度对激光陀螺零偏误差的产生机理，在大量高低温环境试验的基础上，建立了一种通用的零偏温度补偿模型和一种BP神经网络模型，并给出了模型参数的辨识方法，仿真结果表明，对该模型作适当的简化，可以将零偏减小一个数量级以上，而且具有实时补偿性能。
