Abstract

The invention discloses a joint simulation system based on Modelica and a construction method thereof. The method comprises the steps of: establishing a subsystem model in each modeling software; using various different modeling software and languages, for example, a C language model is established in Visual Studio, a Simulink model is established in Simulink, an AMESim model is established in AMESim, a Fortran language model is established in Visual Studio, and the like; compiling each subsystem model to generate a dynamic link library, wherein the dynamic link library comprises a model simulation interface and a model solver; packaging each sub-calculation model into a subsystem Modelica model by utilizing an external function mechanism of Modelica; and finally, writing a master controlmodel by using a Modelica language, defining a sampling step length of each subsystem module, and scheduling each subsystem by using a solver of a master control end to realize data synchronization ofthe system. According to the technology, multi-modeling software and multi-language modeling can be supported, system simulation is divided into system scheduling and subsystem calculation, all subsystems are placed in independent processes to be solved, and the solving speed of the system is increased.

Description

technical field [0001] The present application relates to the technical field of modeling and simulation, in particular, to a Modelica-based co-simulation system and a construction method thereof. Background technique [0002] With the development of science and technology, the subject areas involved in engineering systems are also expanding, such as machinery, electronic control, hydraulics, electricity, computer networks, etc. Modeling and simulation technology has now become an effective tool to support the development of engineering systems, and different disciplines usually have their own unique modeling and simulation analysis software. With the development of the multi-domain unified modeling language Modelica, it has become possible to describe models in different domains with the same modeling language. However, due to historical reasons, usage habits, accumulated experience, intellectual property rights, and the characteristics of modeling in different fields, etc...
