The generic number of system zeros - A bond graph approach

This paper proposes a method to compute the generic number of system zeros of a class of linear time invariant system from a causal bond graph. The method is based on a decomposition of the bond graph representation, achieved using the concept of separators. It is shown that, after decomposition, three partial bond graphs are obtained, each with its own specific properties. These properties only hold because of the structured nature of the system. They are used to compute the generic number of zeros for each partial bond graph, which are then combined to determine the generic number of zeros for the complete bond graph.
