Consistent Initialization of Modelica Models
Liping Chen · Jisuanji fangzhen · 2007
Simulation model described by the Modelica language can be translated into a system of differential algebraic equations. It is necessary to provide some initial conditions before solving a DAE system. The Modelica language was briefly introduced, the way for specifying initial conditions for Modelica models was discussed, a method for obtaining the underlying constraints of a DAE system was proposed, the criterion for determining whether the initial conditions were consistent or not was given, and the strategy for solving the initialization equation system was proposed. The result achieved by applying the discussed method on an oscillator model was illustrated.
