Research on variable parameter set in complex multi-domain physical system and its repeatedly simulating arithmetic

Abstract

As a unified modeling simulation language for complex multi-domain physical system, now Modelica is getting more and more attention, and its compiler and solver method emerges in endlessly. However, up to now little solver method consider the efficiency of repeatedly simulation after modifying variable parameters. Here, a method focuses on improving the efficiency of repeatedly simulation for complex model is set forth. Firstly, elucidate some related definitions such as coupling block, data dependence, coupling block dependent graph, variable parameter set and so on. Secondly, illustrate the hierarchy expression of coupled block dependence graph, variable sub-graph and minimum solution tree. Finally, taking a concrete object as an example, some related conclusions are obtained. © Springer-Verlag London Limited 2009.
