光纤陀螺的零位漂移和刻度因子随温度及温度梯度变化呈现复杂的非线性特征,目前被应用于工程上的常规建模方法的建模效果并不理想。提出了自适应模糊神经网络(ANFIS)的建模方法,它是一种新型的基于模糊神经网络的陀螺温度漂移建模方法,它实现了在模糊逻辑理论框架下同时对光纤陀螺零偏和刻度因子进行建模和补偿,达到了简化温度补偿步骤,提高补偿精度的效果。
Temperature zero drift and scale factor of Fiber Optic Gyro(FOG) present complicated nonlinear characteristics with the variation of temperature. Conventional modeling methods applied in progjects can't give a valid way to describe these characteristics. In this paper, a novel strategy, Adaptive Fuzzy-neurol Inference Systems (AFNIS), is put forward based on temperature drift modeling. This method, under the theory of fuzzy logical, makes a compensation model for temperature zero drift and scale factor at the same time, and it simplifies temperature compensation procedure and improves the accuracy of compensation.
