A Formal Model of Metacontrol in Maude

Abstract

Smart applications now appear in domains spanning from advanced underwater robotics to commodity household applications. These smart applications require adaptation to dynamic environments, changing requirements and internal system errors. Metacontrol takes a systems of systems view on autonomous control systems and self-adaptation, by means of an additional layer of control that manipulates and combines the regular controllers. This paper develops a formal model of a Metacontrol architecture. We formalise this Metacontrol architecture in the context of an autonomous house heating application, enabling different controllers to be dynamically combined in order to meet user requirements to a better extent than the individual controllers in isolation. The formal model is developed in the Maude rewriting system, where we show results comparing different scenarios.
