Modeling and logic control design for production system: a matrix based approach

This paper introduces a novel, more systematic approach to the modeling and control design of machine logic control. The machine logic control is considered to be an event-driven system. A matrix representation of Petri nets is used, for modeling the structure of discrete event-driven system. Its dynamics is described by state-transition equations. The control of discrete event system is introduced by drawing a clear distinction between the plant and the controller model. The proposed approach is illustrated by simulation and experimental results for the lab-scale linear drive position initialization procedure.
