Component-oriented Design and Interaction Semantics Description of Hierarchical Hybrid Control System

Complex control system is heterogeneous and imposes great challenges for control system design. This paper presents a component-oriented design methodology that reduces complexity by separating data-related computational parts and interaction among components. Frameworks are composed hierarchically to manage heterogeneous models and achieve component and framework reuse. We introduce a notion of supervisor to manage the framework and discuss how to aggregate individual component's computation into a well-defined composite computation from a view of interaction semantics denotational framework. A simplified component-oriented hierarchically hybrid control system in a distributed real-time platform is implemented to prove the feasibility and flexibility of our methodology.
