Cooperative reconfiguration of locally interconnected systems with limited model information: A plug-and-play approach
Sven Bodenburg, Jan Lunze · 2016
This paper proposes a cooperative reconfiguration approach after faults have occurred in a locally interconnected system. Although the impact of the fault has effects to all other subsystems through the physical couplings, only the control station of the faulty subsystem should be reconfigured together with neighbouring control stations. The focus of this paper is on the organisation of the reconfiguration process without a central coordinator. Design agents exist for every subsystem which store the model of the respective subsystem. A local search algorithm is presented for the design agent of the faulty subsystem to find supportive design agents and to procure their local models to set-up an adequate model describing the faulty subsystem under the influence of the physical interactions. Furthermore, cooperative reconfiguration conditions are proposed to recover the global performance by the reconfiguration of the assigned control stations based on the limited model information. As a consequence, after the “plug-in” of the control stations into the hardware they “play” together to cooperatively act against the fault. This plug-and-play reconfiguration method is applied to a multizone furnace.
