Petri net-based modeling and simulation of a hybrid manufacturing system

Abstract

Dynamic systems with a mix of continuous and discrete components called hybrid systems frequently arise in engineering applications. By modeling these different components using differential equations and discrete events, it is possible to represent a wide range of phenomena present in physical and technological systems. Since many of these applications are safety critical, if is important to use reliable methods to simulate hybrid systems. In this paper we deal with modeling and simulation of hybrid systems using an extended form of timed Petri net. The proposed method is used for modeling of a robotic manufacturing system. The simulation results are obtained by a modified Petri net toolbox.
