Modeling and simulation method for missile-borne electrical system based on Modelica language

Abstract

The invention is based on an emerging Modelica language in recent years in the field of computer modeling and simulation, and particularly provides a missile-borne electrical system modeling method. The method mainly comprises the following steps of decomposing a missile-borne electrical system into a plurality of unit-level models; carrying out modeling on the unit-level model by adopting a modeling mode of differential equation description or finite element method description or function fitting method description; identifying the unit-level model; assembling the unit-level models into an on-missile electrical system model; and completing simulation of the on-missile electrical system model. According to the method, modeling difficulty and the modeling workload of the missile-borne electrical system can be reduced, so cost is saved, and research and development efficiency of the missile-borne electrical system is improved.

Description

technical field [0001] The invention belongs to the field of computer modeling and simulation, in particular to modeling and simulation of common bomb-mounted electrical equipment based on the Modelica language. Background technique [0002] The electrical system on the missile is a typical complex system, which has the characteristics of complex technology, wide range of disciplines, and strict requirements on safety and reliability. The modeling and simulation technology can simulate the operation of the electrical system before the designed electrical system is put into production, which can save costs and shorten the production cycle. It is an indispensable link in the development of the electrical system on the bomb. [0003] Most of the existing modeling and simulation technologies for electrical systems on missiles are based on modeling and simulation in a single field, such as control, machinery or electronics. Therefore, in order to accurately and completely model ...

Problems solved by technology

[0007] The Modelica standard model library currently contains component models with high versatility in various fields, but it lacks a targeted model library and corresponding modeling process for the missile electrical system. The existing Modelica standard model library cannot meet the needs of complex missile integrated electronic systems. Modeling needs, urgent need for targeted construction and expansion of the model library
