Virtual dynamics of DC circuits
Dalibor Biolek, Zdeněk Biolek · 2002
It is shown in this contribution that besides the classical dynamics caused by reactance elements, each DC resistive circuit has its special hidden so-called virtual dynamics which contains information about the DC operating point stability. Virtual eigenvalues can be attached to each linear model of resistive circuit linearized around its DC operating point. Corresponding virtual trajectories describe motion of operating point in the virtual space after being deflected from the equilibrium state and they help to decide whether the operating point is stable.
