Maximally Permissive One-Step Control without Redundancy for a Class of Discrete Event Systems
Zhu Gengxin · Control theory & applications · 1997
This paper concerns the forbidden-state problem for a class of discrete event systems modelled by marked graphs. Based on the framework given in our previous paper[1], robustness of the permissivecontrol is analyzed for the case in which time delays in control and observation exist. Two approaches arethen presented to search and to determine, respectively, the maximally permissive one-step control policywithout redundancy. Characteristics are given for the concurrent activities' series whose fires preserve thesystem being maximally permisive.
