Abstract :
In this paper, the setup of Zhong-Wonham for hierarchical control of discrete-event systems is extended to the case of control under partial observation. A suitable reporting map is developed for sending information to the high-level supervisor. A partially-observable-strict-output-control-consistency (PO-SOCC) property is introduced to ensure hierarchical consistency.
