预测系统
灰色预测模型称为CM模型,G为grey的第一个字母,M为model的第一个字母。GM(1,1)表示一阶的,一个变量的微分方程型预测模型。GM(1,1)是一阶单序列的线性动态模型,主要用于时间序列预测。 一、GM(1,1)建模 设有数列 共有 个观察值 对 作累加生成,得到新的数列 ,其元素 (5-1) 有: 对数列 ,可建立预测模型的白化形式方程, (5-2) 式中: ——为待估计参数。分别称为发展灰数和内生控制灰数。设 为待估计参数向量 则 按最小二乘法求解, 有: (5-3) 式中: (5-4) (5-5) 将(5-3)式求得的 代入(5-2)式,并解微分方程,有 (1,1)预测模型为: (5-6)(gray forecasting model called CM model, the G-gray of a letter, the M model for the first letter. GM (1,1), a band of a variable type of differential equation models. GM (1,1) is a sequence of single-band linear dynamic model, mainly for time series prediction.

通过 matlab 编程实现捷联惯导系统初始对准、惯导解算的全过程
说明: 通过 matlab 编程实现捷联惯导系统初始对准、惯导解算的全过程。
1)初始自对准:利用前10分钟实验车静止的数据进行惯导系统的自对准。采用前2分钟数据进行解析粗对准,后8分钟数据用五状态Kalman滤波器实现精对准;为了验证精对准性能,可在粗对准结果上把航向角人为加一定幅度(如10度)的误差,观察精对准的收敛性能。
2)纯惯导解算:对准结束后转入纯惯性导航解算,要求进行双子样的圆锥和划摇补偿,即每20ms完成一次导航解算,输出完整的导航结果包括三个姿态、两个水平速度和两个水平位置(天向通道发散不必输出),并给出姿态、速度、位置随时间的变化曲线以及位置误差曲线。(The whole process of initial alignment and inertial navigation solution of strapdown inertial navigation system is realized by matlab programming.)
