Abstract
Model reduction is performed in the frequency domain by matching the first Taylor-series-expansion coefficients of the square magnitude of the original and the approximating transfer functions at suitable frequencies. The method is computationally simple and may lead to a satisfactory approximation while preserving stability and minimum-phase characteristics.Keywords
