Component-oriented design and causality interaction analysis of distributed real-time control system

Complex real-time control system is distributed and imposes great challenges for precise time synchronization modeling. This paper presents a component-oriented design strategy that reduces complexity by separating data-related computational parts and time synchronization interaction among components. We introduce a notion of supervisor to discuss how to aggregate individual component’s computation into a well-defined composite computation from a view of causality interaction analysis. A simplified component-oriented hierarchically real-time embedded control system in a distributed platform is implemented to prove the feasibility and flexibility of our methodology.
