This paper addresses the problem of hierarchical control of discrete event systems with model uncertainty. To achieve the hierarchical consistency under model uncertainty, we derive the conditions on the properties of the information channel between a low level and a high level and the structure of the low level system with model uncertainty. The feasibility of the results obtained is demonstrated in the hierarchical control of a work cell.
