An Investigation of Model-Based Design Framework for Aero-Engine Control Systems

Throughout the design of aero-engine control systems, modeling and simulation technologies have been widely used for supporting the conceptualization and evaluation. Due to the increasing complexity of such systems, the overall quality management and process optimization are becoming more important. This in particular brings the necessity of integrating various domain physical models that are traditionally based on different formalisms and isolated tools. In this paper, we present the initial concepts towards a model-based design framework for automated management of simulation services in the development of aero-engine control systems. We exploit EAST-ADL and some other existing state-of-the-art modeling technologies as the reference frameworks for a formal system description, with the content ranging from requirements, to design solutions and extra-functional constraints, and to verification and validation cases, etc. Given such a formal specification of system V&V (Verification and Validation) cases, dedicated co-simulation services will be developed to provide the support for automated configuration and execution of simulation tools. For quality management, the co-simulation services themselves will be specified and managed by models in SysML.
