Hierarchical supervisory control of discrete event systems based on H-observability
Sung‐Hoon Kim, K.-H. Cho, J.-T. Lim · IEE Proceedings - Control Theory and Applications · 2003
A hierarchical consistency problem for the hierarchical supervisory control of discrete event systems under partial observation is considered, since observability is a practical and general property in real systems. The notion of H-observability is introduced to ensure hierarchical consistency between low- and high-level systems, and an analytical framework for the hierarchical supervisory control is established.
