Abstract

Common practice in the simulation of continuous systems is to discretize the time in order to obtain a numerical solution. The Quantized State System (QSS) approach makes it possible that the discretisation is applied to the state variables, instead of the time range. In other words continuous systems can be simulated event-based with the QSS method. It also effects a new orientation and leads among other things to very effi-cient state event detection. Ernesto Kofman and Sergio Junco presented the QSS method in the DEVS formalism. This paper describes how the implementation of the QSS method in Simulink/SimEvents works and which restrictions still exist.
