Interval observer versus set-membership approaches for fault detection in uncertain systems using zonotopes
(2019-01-01)
Article
Restricted access - publisher's policyThis paper presents both analysis and comparison of the interval observer–based and set-membership approaches for the state estimation and fault detection (FD) in uncertain linear systems. The considered approaches assume ... -
Optimal state observation using quadratic boundedness: application to UAV disturbance estimation
(2019-03-01)
Article
Open AccessThis paper presents the design of a state observer which guarantees quadratic boundedness of the estimation error. By using quadratic Lyapunov stability analysis, the convergence rate and the ultimate (steady-state) error ... -
Experimental testing of variable speed heat pump control strategies for enhancing energy flexibility in buildings
(Institute of Electrical and Electronics Engineers (IEEE), 2019-01-01)
Article
Open AccessThermal mass of buildings and domestic hot water tanks represent interesting sources ofthermal energy storage readily available in the existing building stock. To exploit them to their full potential,advanced control ... -
Interval observer-based fault detectability analysis using mixed set-invariance theory and sensitivity analysis approach
(2019-01-01)
Article
Restricted access - publisher's policyThis paper addresses the characterization of the minimum detectable fault (MDF) by means of residual sensitivity integrated with the set-invariance theory when using an interval observer-based approach as a Fault Detection ... -
FD-ZKF: A Zonotopic Kalman Filter optimizing fault detection rather than state estimation
(2019-01-01)
Article
Restricted access - publisher's policyEnhancing the sensitivity to faults with respect to disturbances, rather than optimizing the precision of the state estimation using Kalman Filters (KF) is the subject of this paper. The stochastic paradigm (KF) is based ... -

Frequency-based detection of replay attacks: application to a multiple tank system
(2018-01-01)
Article
Open AccessThis paper presents a benchmark for the detection and isolation of cyber attacks, which is a non-linear controlled interconnected system based on a two tank system. In this benchmark, a malicious attacker wants to remain ... -
Game-theoretical methods in control of engineering systems: an introduction to the special issue
(2017-02-01)
Article
Open AccessThere has been increasing interest in the control community in studying large-scale distributed systems, and numerous techniques have been developed to address the main challenges in these problems. One way to approach ... -
Optimal sizing of storage elements for a vehicle based on fuel cells, supercapacitors, and batteries
(2019-01-01)
Article
Open AccessTo achieve a vehicle-efficient energy management system, an architecture composed of a PEM fuel cell as the main energy source and a hybrid storage system based on battery banks and supercapacitors is proposed. This paper ... -
Interval observer fault detection ensuring detectability and isolability by using a set-invariance approach ¿
(2018-01-01)
Article
Open AccessThis paper proposes the design of an interval observer-based Fault Detection and Isolation (FDI) algorithm using the set-invariance approach. Using this approach, both fault detectability and isolability properties of the ... -
Robust fault and icing diagnosis in unmanned aerial vehicles using LPV interval observers
(2018-01-01)
Article
Open AccessThis paper proposes a linear parameter varying (LPV) interval unknown input observer (UIO) for therobust fault diagnosis of actuator faults and ice accretion in unmanned aerial vehicles (UAVs) describedby an ... -
Grid voltage regulation using a reset PI+CI controller for energy storage systems
(2018-01-01)
Article
Open AccessHybrid controllers are capable of improved performance over their linear counterparts. In particular, reset controllers like the PI+CI are capable of fast flat response for lag dominant plants. Grid connected power converters ...
