Modeling and simulation of dynamic structure heterogeneous flow systems
The author presents the Heterogeneous Flow System Specification (HFSS), a formalism suited to represent combined (discrete/continuous) systems. The new formalism is based on the concept of sampling that is described in general terms to include multirate sampling systems. The HFSS formalism permits the construction of continuous/discrete input/output models in a modular and hierarchical manner. Hierarchical systems have a dynamic structure nature that can be changed over time. To show an application of the HFSS formalism, the author presents a new formalism to numerically solve differential equations with discontinuities using multirate integration methods. Applications of combined and dynamic structure systems are presented.
