Abstract

A hybrid system is defined as a system with
mixed discrete event and continuous parts. Two approaches
for modeling and simulation of hybrid systems in
the context of the Discrete EVent System Specification
(DEVS) formalism are compared. Since the system theoretic
DEVS approach has been introduced during the 1970ies,
it has been completed by different extensions. The hybrid
extensions checked against each other here, are the Quantized
State Systems (QSS) method and a wrapper concept
based on traditional ODE solvers. For a comparison from
engineering practice point of view, these two hybrid DEVS
approaches are analyzed within the scientific and technical
computing environment MATLAB.
