A Decentralized Service Based Architecture for Design and Modeling of Fault Tolerant Control Systems
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. In each
module of the control system, diagnosis and reconfiguration
are included and use only locally available
signals. Therefore, no extra dependencies are
added to the control system software, something
which is important to facilitate efficient engineering
of large scale system. All 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.
