Construction And Application Research On Automatic Modeling And Simulation Platform Based On Modelica Language

Electro circuit emulation software is important for the analysis and design of modern electronic circuits. It can shorten the development time and reduce the development cost effectively. But with the development of science and technology, the integration level of electronic circuit increases continuously and the structure of it is much more complex, which have added to the difficulty of modeling and increased the time of simulation; For the widly and deeply application of electronic circuits in related fields, such as mechanics, hydraumatic, thermos dynamics and control, the multi-field modeling and simulation technology is indispensable to conduct a complete modeling and simulation of a system. Therefore, this paper presents the construction of automatic modeling and simulation platform based on Modelica with the aid of Modelica modeling and simulation technology, to achieve the modeling and automatic simulation of complex circuit.The main purpose of this design is to construct the Modelica automatic modeling and simulation plateform based on Open Modelica software, and realize the application of it. To construct the plateform, the overall scheme is drawn from the researching of modeling and simulation technology based on Modelica language.First, the technology of the modeling and Simulation based on Modelica language is studied, including the Modelica modeling method, the architecture and working mechanism of Openmodelica modeling and simulation software 。Then put forward the overall scheme of the construction of Modelica automatic modeling and simulation platform based on the research above.Secondly, regarding the low reusability of the Modelica editor codes, and according to the modularization system design idea, this paper divides the system into multiple function modules, and calls function modules to reconfigurate a highly-reusable Modelica editor.Then, through the optimal design of the reusable Modelica editor, the simulation model import module, the continuous simulation module, and the simulation result processing module are built, the Modelica automatic modeling simulation platform is established and the functions of this platform are verified.Finally, the Modelica automatic modeling and simulation platform is applied in the field of circuit system design and the fault diagnosis. To demonstrate the superiority of the platform built in this paper on modeling and simulation, this paper compares this platform with the PSpice software.
