A TIME-DOMAIN APPROACH TO CONTINUOUS-TIME MODEL IDENTIFICATION OF HIGHLY RESONANT WIDE-BAND SYSTEMS

摘要

The purpose of this paper is to present some issues that arise when applying a traditional continuous-time model identification technique to highly resonant systems over a large bandwidth. A scheme based on the use of frequency localising basis functions to improve the numerical conditioning of the identification problem is examined. Examples are presented showing the superior performance of the proposed method when applied to wideband estimation problems.
