摘要
考虑线性定常系统的数字仿真,状态变量的计算步长为T,而系统输出的计算间隔常常为NT,本文通过以多项式插值函数逼近系统输入,利用增广矩阵法的结果,给出了基于离散相似法的一类仿真算法,当N较大时,与一般同类算法相比,本文算法使计算量显著减小。
In course of the simulation of a linear time-invariant system, T is the calculating step of the state variabies, and the system output is usually calculated at intervals of AT. Using polynomial interpolating function to approximate the, system input and introducing the result obtained with augmented matrix algorithm, a fast simulation algorithm based on discrete analog method is presented in this paper. When N is large, the algorithm has much smaller computing amount than other similar algorithm.
