Model-based Implementation of an Onboard STANAG 4586 Vehicle Specific Module for an Air Vehicle

摘要

This paper describes aspects of the system and model-based software design for a Vehicle Specific Module compliant to the NATO interoperability standard STANAG 4586 Edition 3 for Unmanned Air Vehicle Control Systems. The module enables controlling and monitoring of an air vehicle from a ground control station. It thereby serves as converter between custom interfaces of the controller on the one side, and an event-based communication based on data link messages described by the standard on the other side. The paper discusses important concepts of STANAG 4586 and outlines their adaption for the use in a manned research aircraft. Based on the system concept, the model-based software design in MATLAB Simulink/Stateflow is derived. Software details concerning a hybrid architecture merging auto-generated and conventionally programmed code as well as software interfaces are highlighted and presented in the context of modeling techniques for high-integrity systems.
