EIS, Volterra series, Orthogonal Periodic Sequence, Multiple Variance Identification
The aim of this research activity is to identify the linear part of a non-linear system using a technique that is fundamentally different than the traditional small-signal system identification. This technique can be applied to estimate the impedance of a non-linear system, like a Lithium-ion battery, or the linear part of any system that is affected by non-linear distorsions of the measurement system.
