该文采用线性化方法建立了一类飞行器在其运动轨迹上一组特征点上的多变量数学模型,包括对象的状态方程矩阵A、B、C、D及传递函数矩阵.通过对大量数据计算和分析,查明了系统极点摄动的某些重要规律和传递函数矩阵的重要性质,为设计飞行器的多变量鲁棒控制器提供了关键性的依据.
In this paper, we establish a multivariable mathematical model of a class of aircraft on a set of feature points on its trajectory using the linearization method, including the state equation matrix A, B, C, D and the transfer function matrix of the object.By calculating the large amount of data And analyzed and identified some important laws of the system pole perturbation and the important properties of the transfer function matrix, which provided a key basis for designing a multivariable robust controller of an aircraft.
