The object of this paper is to propose a method to deal with the problem of modeling user specifications in approaches based on supervisory control and Petri nets. However, most of Petri net approaches are based on forbidden states specifications, and these specifications are suitable the use of tool such as the reachability graph. But these methods were not able to show the user specification easily and these formalisms are generally limited by the combinatorial explosion that occurs when attempting to model complex systems. Herein, we propose a new efficient method using FSSTP (forbidden sequences of state-transitions problem) and theory of region. Also, to detect and avoid the deadlock problem in control process, we use deadlock avoidance Petri nets method for solving this problem in control model.
