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。

In the model solution method's choice, according to the mix integer model's characteristic, the paper proposed to divide the model solution into two parts. The linear segment used the transportation plan method to solve and the mis alignment part used the implicit enumeration to solve. Finally the paper proved the model's feasibility through the example to solve the location-selection for the distribution center and obtained the quite satisfactory the location-selection result.
