Description
The main contribution of this work is to provide new insights for capturing the behavior of hard nonlinearities beyond the classical weakly nonlinear Volterra input-output map (VIOMAP). The VIOMAP approach is a special polynomial map unable to capture hard non-linearities due to the ill-conditioned high polynomial terms. On the other hand, the describing functions (DF) framework allows more general map constructions such as rational, which makes the hard non-linear behavior more stable for approximation. Data-driven methods as the Loewner framework (LF) can benefit from that concept.
