Distributed Contaminant Detection and Isolation for Intelligent Buildings
Kyriacou, Alexis; Michaelides, Michalis P.; Reppa, Vasso; Timotheou, Stelios; Panayiotou, Christos G.; Polycarpou, Marios M. (2018)The automatic preservation of the indoor air quality (IAQ) is an important task of the intelligent building design in order to ensure the health and safety of the occupants. The IAQ, however, is often compromised by various ...

Distributed Design of Sensor Fault-Tolerant Control for Preserving Comfortable Indoor Conditions in Buildings⁎⁎This work was supported by the European Research Council under the ERC Advanced Grant ERC-2011-AdG-291508 and by the European Union’s Horizon 2020 research and innovation programme under grant agreement No 739551 (KIOS CoE).
Papadopoulos, Panayiotis M.; Reppa, Vasso; Polycarpou, Marios M.; Panayiotou, Christos G. (2018)This paper proposes a distributed fault-tolerant control (FTC) scheme that can preserve thermal comfort conditions in a multi-zone building despite the presences of faulty temperature sensors. The proposed methodology ...

Optimization of observer design for sensor fault detection of nonlinear systems
Reppa, Vasso; Timotheou, Stelios; Polycarpou, Marios M.; Panayiotou, Christos G. (2017)This paper presents an optimization methodology for the design of an observer-based sensor fault detection scheme for a class of nonlinear systems. Taking into account bounded system disturbances and measurement noise, we ...
