Determination of an Impedance Operator of Time-Varying Dynamic Two Terminals on the Basis of the Terminal Signals Measurements

This paper presents the derivation and effects of a genuine algorithm for identification of circular parametric operators describing performance of periodically time-varying systems, of one input – one output type. The periodic steady state is taken into the consideration, while the period of the change of the system parameters overlaps the period of the changes of input and output signals. Within the domain of discrete time, such operators take the form of a real element matrix. A circular parametric operator may be transformed into the frequency domain. In this version, the quantitative assessment of mixing and generating of harmonics of input and output signals is possible. The original identification algorithm is used for determination of time-varying two-terminal impedance. Some results of computer simulations are presented.
