Abstract:

In this paper we consider the structural analysis problem for differential‐algebraic systems with conditional equations. This problem consists, given a conditional differential‐algebraic system, in verifying if the system is structurally nonsingular for every state, and if not in finding a state in which the system is structurally singular. We give a formulation for this problem as an integer linear program. This is based on a transformation of the problem into a matching problem in an auxiliary graph. We also show that the linear relaxation of that formulation can be solved in polynomial time. Using this, we develop a Branch‐and‐Cut algorithm for solving the problem and present some experimental results.
