Application of reducible cutset and reducible loop to analysis of the network

Abstract

New concepts of reducible independent cutset and reducible independent loop are developed through an analysis of the ladder network. A new analytic method, named structural analysis method, is presented. It evaluates the controllability and observability of a network based on its structure rather than on its state equation. Some problems in the conventional network analysis can be solved using this method. Results obtained by this method are in good agreement with those obtained by that of state space analysis, but this method is much simpler in use. A practical example is given.
