摘要：

This paper introduces an improved procedure for the identification of a transfer function from phase angle data with prescribed frequency variation. It is shown how a transfer function can be identified from phase response data samples, by fitting a normalized function with constant magnitude using the vector fitting, algorithm. The presented approach is numerically robust and leads to more accurate results than conventional approaches. (C) 2009 Elsevier GmbH. All rights reserved.
