将小波网络理论及其改进方法应用于光纤陀螺的启动漂移温度补偿,在进行全温范围启动漂移试验的基础上,综合考虑温度、温度梯度和温变率对启动漂移的影响,建立了光纤陀螺的启动漂移模型,并根据模型进行补偿,以提高光纤陀螺启动条件下的测试精度。试验结果表明,采用小波网络能够有效地补偿光纤陀螺的温度启动漂移,从而满足实时应用的要求。
The wavelet network theory and its improved method are applied to the startup drift temperature compensation of fiber optic gyroscope. Based on the start-up drift test in the whole temperature range, the influence of temperature, temperature gradient and temperature change on startup drift is considered, Of the starting drift model, and compensate according to the model, in order to improve the test accuracy under the FOG startup condition. The experimental results show that the wavelet network can effectively compensate the temperature drift of fiber optic gyroscope to meet the real-time application requirements.
