Stable Macromodels for Delayed PEEC Models with Error Estimation

A robust model order reduction method for large-scale PEEC models with many delays is proposed. The method reduces the size of the original model by interpolating the transfer function of the time-delayed system. The resulting reduced-order model is accurate both in the frequency domain and in the time domain. Moreover, the reduced-order model successfully filters the instability behavior of the original model and exhibits stability over a large time interval.
