摘要

在频域识别中，数值调节和可辨识性是关键因素。针对这两个主题，研究了传递函数模型中时延的独立频率标度，包括普通s域描述和正交多项式。在估计过程中，提出了一种与设备无关的缩放算法和经验法则。

Independent scaling of a delay in frequency domain system identification

Numerical conditioning and identifiability are key factors in frequency domain identification. Independent frequency scaling of the delay in transfer function models is studied in view of these two topics, both for ordinary s-domain descriptions as well as for orthogonal polynomials. An algorithm and a rule of thumb are proposed for device independent scaling during estimation sessions.
