Abstract: One of the difficulties of the numerical integration methods for
differential-algebraic equations (DAEs) is the computation of consistent
initial values before starting the integration, i.e.,
to calculate values that satisfy the given algebraic constraints as well
as the hidden constraints if higher index problems are considered.
This paper presents an algorithm that permits the consistent
initialization of index 1 or 2 DAE-systems resulting from electric circuit
simulation by means of modified nodal analysis (MNA). The
presented approach arises from the topological properties of the network
and holds for circuits that may contain some specific controlled sources.
Keywords: Consistent initial values; consistent initialization;
differential-algebraic equation; DAE; index; circuit simulation; modified
nodal analysis; MNA; structural properties; graph
theory.
