Hierarchy Modeling for Component-based Complex Control Software

Complex control software is heterogeneous and difficult to design. This paper presents a component-based hierarchy modeling strategy that divides the basic computational parts into components and separates interaction among components as pattern. Under the support of hierarchy architecture, component and pattern achieve reuse. We introduce a notion of behavior generator to characterize the property that the architecture can aggregate individual component´s computation into a well-defined composite computation such that heterogeneous models can be composed. A simplified component-oriented hierarchically hybrid control software is implemented to prove the feasibility and flexibility of our methodology.
