摘要
基于飞行器法向过载方程,首先采用逐步回归分析方法对气动力系数的多元线性回归模型进行因子筛选,确定气动模型结构,然后用逐步回归分析法的结果作为初值,用实时递推最小二乘法估计气动力参数。
Based on the aerocraft longitudinal gas-dynamics equation,a regression analysis method is adopted to select the factors for the linear regression model of the aerodynamic parameters,then the structure of the aerodynamic model is determined.Taking the result of the regression analysis method as the initial value,the recursive least square method is used to estimate aerodynamic parameters.
