摘要
通过对惯性导航系统误差来源分析,分别建立加速计和陀螺仪的误差纠正补偿模型,对飞行器坐标观测值的随机波动误差进行修正。然后通过建立动态神经网络来实现对导航系统的积累误差纠正补偿,利用神经网络误差反向传递,强大的处理非线性系统能力,来对惯导积累误差的修正补偿,从而实现对飞行器长时间飞行空间坐标的精准定位。
In this paper,through the analysis of the errors of inertial navigation system,error correction compensation models were built in accelerometer and gyroscope,and then a dynamic neural network was built to realize the navigation system with error correction compensation by using the neural network and error back transfer,strong nonlinear processing ability,and correction and compensation to accumulated error of INS to realize the correction of the vehicle space coordinates.
