A service based approach to decentralized diagnosis and fault tolerant control

Abstract

Abstract-The paper presents a hierarchical architecture for fault tolerant control of mechatronic systems. In the architecture, both the diagnosis and the reconfiguration are completely decentralized according to the structure of the control system. This is achieved by using a purely service oriented view of the system including both hardware and software. The service view with no cyclic dependencies is further used to obtain Bayesian networks for modeling the system.
