Cooperative fault-tolerant control of networked systems

Fault-tolerant control is an important means to avoid safety-critical situations and shut-downs of machines and processes due to the occurrence of faults or failures. The scientific aim of the project is to elaborate new methods of fault-tolerant control of networked systems such that the function of the overall system is retained by re-distributing the overall control aim among the subsystems after a failure has occurred and a subsystem is no longer able to satisfy its aim. The architecture used does not include a coordinator, but the subsystems have to make their decisions based on local information and information that they have received over a digital network. The components of the new fault-tolerant control architecture should be elaborated in three steps, which concern the design of networked trajectory-following controllers, the decentralised fault diagnosis and the cooperative reconfiguration of the control units. The results will be experimentally evaluated.
