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 ...
Comparative analysis of parameter extraction techniques for the electrical characterization of multi-junction CPV and m-Si technologies
(2018)
Modelling the current-voltage (I-V) characteristics of photovoltaic (PV) modules under real operating conditions is crucial for the better understanding of each technology. The most commonly used model for the electrical ...
ALCHEMI – A low cost, high efficiency, optoelectronic HCPV module for 1000× operation
(2018)
his paper summarizes the current status of the ALCHEMI project, a European collaborative undertaking under the Solar-Era.Net co-fund scheme. The project’s aim is to develop novel, low cost, HCPV modules that operate at ...
Optimal Estimation via Nonanticipative Rate Distortion Function and Applications to Time-Varying Gauss--Markov Processes
(2018)
In this paper, we develop finite-time horizon causal filters for general processes taking values in Polish spaces using the nonanticipative rate distortion function ($NRDF$). Subsequently, we apply the $NRDF$ to design ...
Control-Coding Capacity of Decision Models Driven by Correlated Noise and Gaussian Application Examples
(2018)
We characterize the n -finite time feedback information (FTFI) control-coding capacity of decision models (DMs) driven by correlated noise. Under information stability the per unit limit, called control-coding (CC) capacity ...
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. ...
Effective Prediction of Road Segment Occupancy for the Route-Reservation Architecture
(2018)
The effect of traffic congestion within an urban region can be eliminated by curbing the number of vehicles that use the congested part of the transport network. To do so, earlier work by the authors introduced a novel ...
