摘要: <正> 近些年来,在系统的辩识、分析及最优控制方面出现了一些利用正交函数逼近处理的数值方法,诸如沃尔什函数、切比雪夫多项式、勒让德多项式、拉盖尔多项式及富里叶级数。Sparis(1985)及Lee(1987)等学者将Taylor级数应用于系统的分析及最优控制。本文将Taylor级数应用于一类非线性时不变系统的辩识。

Abstract: In this paper, the Taylor Series approach is eitented to the parameter identification of non-linear time-invariant systems. Owing to the extreme simplicity of the operational matrix of integration, it is very convenient to process with the algorithm.
