Joint simulation method based on model development

Abstract

The invention discloses a joint simulation method based on model development. The joint simulation method comprises the steps of: performing system prototype development, control algorithm design, aero-engine modeling and algorithm verification, forming a system prototype, configuring simulation parameters, and generating a DLL; importing and packaging the generated DLL to form a packaging model; integrating the packaging model with other software design models; packaging the fully verified SCADE software design model into an FMU model; and in the INCHRON simulation platform, importing an FMU model corresponding to the generated SCADE, carrying out model integration on the FMU model and FMU models of other subsystems in the INCHRON, carrying out joint simulation, and analyzing the rationality of the whole system design. Through model interaction and information fusion between different development stages and different development platforms, the SCADE software design model is fed back to the INCHRON comprehensive simulation environment to carry out system-level model synthesis and joint simulation, a more complete MBSE solution is formed, and the research and development quality and efficiency of a complex system are improved.

Description

technical field [0001] The invention belongs to the technical field of aeroengine numerical control system and control software development, relates to model-based development and verification technology, and in particular to a joint simulation method in model-based development. Background technique [0002] In recent years, Model-Based System Engineering (MBSE, Model-Based System Engineering) has been more and more applied in the development of complex systems such as aviation, aerospace and rail transportation. MBSE advocates supporting and continuing the whole process of system development in the form of models, gradually replacing documents with digital models as information carriers, and gradually replacing physical test methods with virtual verification methods such as simulation. In MBSE, computer language is used instead of natural language to transmit engineering information. The core idea is to ensure that in the development of large and complex systems, the design...

Problems solved by technology

[0003] At present, there is no standard framework and solution for model-based system engineering in the world. Rhapsody, MATLAB, SCADE and other tools are used for system and subsystem analysis and design. In the process of complex system analysis and design to subsystem detailed design, only Relying on the experience of engineers and discrete modeling and simulation tools, modeling and simulation focus more on the evaluation of functions, and lack of approaches, platforms and methods for virtual synthesis of complex system architecture, dynamic behavior and functions
