Abstract

Supervisory control theory is now well developed, but its use in industrial applications can be limited by a set of problems arising from implementation of supervisors on common control machines. The asynchronous nature of supervisors and the fact that they are non-deterministic models make their implementation on synchronous devices like Programmable Logic Controllers or Personal Computers not a simple task. This paper discusses the main problems occurring in such implementation. A method is proposed to translate a PN supervisor in one of the IEC 61131-3 standard languages, by preserving the closed loop behavior as expected from the theory.
