ACTIVE
PROJECT
Project: VEGA 1/0483/21: „Distributed fault diagnosis of structurally non-distributed systems
(2021-2023)”
Investigators: Dusan Krokavec, Anna Filasova
Project summary: Project is focused on system
fault detection in distributed architectures, consisting from local fault
detectors (agents) created on different kind of cooperative system sub-state
observers and implementing consensus techniques in fault occurrence decision.
Relevant part of the project is basic research, driven in conditions
development for fault isolation in a distributed scheme for systems with
heterogeneous non-distributed interactions. The scientific points and
objectives of the project are dedicated to distributed schemes of detection
nodes and information transmission between some of them, mixing procedures of
state reconstruction of the overall system from local state estimates,
distributed Kalman filtering, interval observers
design, positive observer representation and residual filter optimization in
linear matrix inequality framework, and adaptive consensus design.
