Design of a decentralized detection filter for a class of interconnected systems Conference Paper uri icon


  • In this paper, we consider the problem of designing a decentralized detection filter for a class of homogeneous interconnected systems; in this class of systems, all subsystems have identical structure. A fault in a subsystem propagates via interactions with other subsystems in the collection. The decentralized detection filter is composed of interacting detection filters, one for each subsystem. We assume communication of state estimates amongst subsystems to be feasible. A concern, dealt with here, is that of propagation of state estimation errors. It is treated as a H filtering problem with full state information, by requiring the transfer function from the propagated input of the ith subsystem to that of the (i + 1)st subsystem to have a magnitude less than unity at all frequencies.
