Semantically Enhanced Online Configuration of Feedback Control Schemes
(2018)
Recent progress toward the realization of the “Internet of Things” has improved the ability of physical and soft/cyber entities to operate effectively within large-scale, heterogeneous systems. It is important that such ...
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).
(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 ...
Centralized Fault Detection of Complex Uncertain Hybrid Systems ⁎⁎This work has been supported by the European Union’s Horizon 2020 research and innovation programme under grant agreement No 739551 (KIOS CoE) and from the Government of the Republic of Cyprus through the Directorate General for European Programmes, Coordination and Development.
(2018)
This paper presents a centralized fault detection scheme for hybrid systems with nonlinear uncertain continuous dynamics and measurement noise. The scheme features a modular observer based on a modified hybrid automaton ...
Reducing Vulnerability to Cyber-Physical Attacks in Water Distribution Networks
(2018)
Cyber-Physical Systems (CPS), such as Water Distribution Networks (WDNs), deploy digital devices to monitor and control the behavior of physical processes. These digital devices, however, are susceptible to cyber and ...
Distributed Sensor Fault Accommodation of Multi-Zone HVAC Systems
(2018)
This paper presents a distributed methodology for controlling multi-zone Heating, Ventilation and Air-Conditioning (HVAC) systems and a fault accommodation scheme for reconfiguring the distributed controller in the presence ...
COMOB: A MATLAB toolbox for sensor placement and contaminant event monitoring in multi-zone buildings
(2019)
The monitoring of the indoor air quality against the presence of contaminant sources is of paramount importance since it directly influences the occupants comfort, productivity, health and safety. Various approaches exist ...
Performance Index for Optimizing Sensor Fault Detection of a Class of Nonlinear Systems
(2018)
This paper develops a performance index that can be used to find the optimal design parameters of the observer-based residual generator and adaptive threshold of a fault detection scheme for a class of nonlinear systems. ...
Online Approximation of Prediction Intervals Using Artificial Neural Networks
(Springer International Publishing, 2018)
Prediction intervals offer a means of assessing the uncertainty of artificial neural networks’ point predictions. In this work, we propose a hybrid approach for constructing prediction intervals, combining the Bootstrap ...
Queue-Based Resampling for Online Class Imbalance Learning
(Springer International Publishing, 2018)
Online class imbalance learning constitutes a new problem and an emerging research topic that focusses on the challenges of online learning under class imbalance and concept drift. Class imbalance deals with data streams ...
Path-based joint demand management and route guidance for multi-region traffic networks
(2019)
This work investigates the joint optimization problem of demand management and route guidance to minimize the time spent of vehicles in traffic networks characterized by well-defined regional fundamental diagrams. To account ...
