摘要

This paper studies the design of supervisory controllers with a minimum number of monitor places for Manufacturing System modeled as safe Petri Nets. The proposed approach considers a class of safety specifications known as Behavioral Constraints with a restricted syntax. The set of Behavioral Constraints are represented as predicate logic formulas in normal conjunctive form. Then, each Behavioral Constraint induces a set of algebraic linear inequalities. The approach establishes an equivalence in order to minimize the number of monitor places. Thus, each Behavioral Constraint induces a single linear inequality, giving rise to a 1-monitor place Petri Net supervisor. The approach is illustrated with the design and implementation of 1-monitor place modular supervisor for an automated manufacturing prototype.
