Modelling and Control of Discrete-Event Systems Using Petri Nets and Arduino Microcontrollers

Abstract

The main aim of proposed article is the design of new software system for modelling and control of discreteevent and hybrid systems using Arduino and similar microcontrollers. In this paper we propose a new tool. It is based on Petri nets and it is called PN2ARDUINO. It offers a capability of communication with the microcontroller. Communication with the microcontroller is based on modified Firmata protocol so control algorithm can be implemented on all microcontrollers that support this type of protocol. The developed software tool was successfully verified for control of laboratory systems. It can also be used for education and also for research purposes as it offers a graphical way for designing control algorithm for hybrid and mainly discrete-event systems. Proposed tool can enrich education and practice in the field of cyberphysical systems (Industry 4.0).
