Characterisation of interval-observer fault detection and isolation properties using the set-invariance approach
(2019-01-01)
Article
Open AccessThe aim of this paper is to provide a robust Fault Detection and Isolation (FDI) approach that combines the set-invariance approach with a zonotopic interval observer. The effect of the uncertainty is taken into account ... -
Characterization of the minimum detectable fault of interval observers by using set-invariance theory
(IEEE Press, 2016)
Conference report
Open AccessThis paper addresses the characterization of the minimum detectable fault when using interval observers. The interval observers consider both input and uncertainty as unknown but bounded. The minimum detectable fault using ... -
Comparison of set-membership and interval observer approaches for state estimation of uncertain systems
(2016)
Conference report
Open AccessThis paper presents the analysis and comparison of interval-observer-based and set-membership approaches for the state estimation of linear uncertain systems. In both approaches noise and disturbances are assumed to be ... -
FD-ZKF: A Zonotopic Kalman Filter optimizing fault detection rather than state estimation
(2019-01-01)
Article
Open AccessEnhancing 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 ... -
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 ... -
Interval observer versus set-membership approaches for fault detection in uncertain systems using zonotopes
(2019-01-01)
Article
Open AccessThis 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 ... -
Interval observer-based fault detectability analysis using mixed set-invariance theory and sensitivity analysis approach
(2019-01-01)
Article
Open AccessThis 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 ... -
Observer-based sensor fault detectability: about robust positive invariance approach and residual sensitivity
(2017-07-01)
Article
Open AccessThis paper considers detectability of deviation of sensors from their nominal behavior for a class of linear time-invariant discrete-time systems in the presence of bounded additive uncertainties. Detectable sensor faults ... -

(2017)
Conference report
Open AccessThis paper considers detectability of deviation of sensors from their nominal behavior for a class of linear time-invariant discrete-time systems in the presence of bounded additive uncertainties. Detectable sensor faults ... -
On robust interval observer design for uncertain systems subject to both time-invariant and time-varying uncertainties
(2020-06-05)
Article
Open AccessThis paper proposes the design of an interval observer-based approach for linear dynamic systems aected by both time-invariant and time-varying uncertainties. First, dierent interval observer schemes are compared and ... -
Reduced-order interval-observer design for dynamic systems with time-invariant uncertainty
(2017)
Conference report
Open AccessThis paper addresses the design of reduced-order interval-observers for dynamic systems with time-invariant uncertainty. Because of the limitations of using the set-based approach to preserve the time dependency of parameter ... -

Article
Open AccessThis paper addresses the design of reduced-order interval-observers for dynamic systems with time-invariant uncertainty. Because of the limitations of using the set-based approach to preserve the time dependency of parameter ... -
Robust zonotopic observer design: Interval observer versus set-membership approaches
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessThe aim of this paper is to provide a robust observer design using a Linear Matrix Inequality (LMI) technique along with the analysis and comparison of the interval observer and set-membership approaches within the state ...
