The equivalent circuit of a joining two-port

An equivalent circuit of a joining two-port is proposed. The two-port provides for the stability and convergence of the results of semi-natural modeling of a partitioned linear dynamical system to the results of numerical modeling of the integral original system. The functional properties of the obtained two-port are investigated. It is shown that the obtained results are coupled with the well-known results in the decomposition methods and system modeling by parts. It is supposed that the obtained two-port is one of the simplest hypostases of the Poincare–Steklov operator.
