Abstract:

In order to reduce high lift system design errors, avoid physical verification and iteration, accelerate the development progress, this paper proposes a model-based system requirements validation and verification technology throughout the development stages of the whole life cycle including joint definition, preliminary design, detailed design and integrated verification. This technology integrates Simulink and SCADE models into a unified virtual integration platform through ADS2 software. The system architecture model and system performance model are respectively created and simulated based on this platform, which realizes the validation and verification of system requirement at different stages of research and development. In addition, using ADS2-enabled I/O driver modules, reusing test cases and user interfaces established during the design phase, a computer-in-the-loop semi-physical integration environment, control subsystem integration environment and a fully physical integration verification environment can be quickly built to support hierarchical verification of system requirements. Because unified models and test cases are used at various stages of R&D to convey information, which ensures consistency of information transmission during R&D, greatly reduces design errors, accelerates the R&D cycle, and reduces R&D costs.
