Abstract
The modified minimum phase, all pass, and delay (MAD) method for black-box modeling is proposed and validated. Using this method, a black-box system is modeled as three parts, a minimum phase subsystem, an all-pass subsystem, and a delay term. Since this model precisely capture the physical characteristics of complicated networks in a wide frequency range, it significantly improves both the modeling efficiency and accuracy compared to existing rational function approximation methods.
