In this article we propose a new graphical method for modeling
sequential controllers using high-level colored Petri nets. We will
present how to build a sequential controller using this method and
analyze its state space. The results in this stud
y showed an
advantage of the controller designed by the new method compared
to which designed algebraically by ordinary Petri net in complex
systems. The new method simplify the sequential controller network
and increase the performance speed and improve the reliability.
