ABSTRACT
This paper presents a distributed, hierarchical control
scheme for autonomous resource management in com-
plex embedded systems that can handle dynamic
changes in resource constraints and operational re-
quirements. The developed hierarchical control structure
handles the interactions between subsystem and sys-
tem-level controllers. A global coordinator at the root of
the hierarchy ensures resource requirements for the du-
ration of the mission are not violated. We have applied
this approach to design a three-tier hierarchical control-
ler for the operation of a lunar habitat that includes a
number of interacting life support components.
