Abstract

This paper presents a frequency domain identification method for the rational transfer function using TLS (total least squares) approach. The proposed method identifies the coefficients of rational polynomial transfer function for continuous time system, after rearranging the two-dimensional input matrices and output vectors obtained from the observed frequency responses
