Design of an unknown input observer for fault diagnosis of non-linear systems with state constraints Witczak, Marcin; Puig Cayuela, Vicenç; Dziekan, L. (2012)
Restricted access - author's decisionThe paper deals with the problem of designing observers for a class of discrete-time nonlinear systems with an unknown input. In particular, with the use of the Lyapunov method, a design procedure of an asymptotically ...
Determination of an unknown input distribution matrix for non-linear discrete-time stochastic systems Jozefowicz, Rafal; Witczak, Marcin; Puig Cayuela, Vicenç (2012)
Restricted access - confidentiality agreementThe paper deals with the problem of estimating an unknown input distribution matrix for non-linear discretetime stochastic systems. In particular, it is shown how to use the unscented Kalman filter as an unknown input ...
Luzar, Marcel; Witczak, Marcin; Puig Cayuela, Vicenç; Nejjari Akhi-Elarab, Fatiha (2009-11-19)
Open AccessThe main objective of this paper is to present the MATLAB block-set that can be used for faulttolerant control of linear-parameter varying systems. In particular, the introductory part of the paper presents a theoretical ...
Fault-tolerant control strategy for actuator faults using LPV techniques: Application to a two degree of freedom helicopter Montes de Oca, Saúl; Puig Cayuela, Vicenç; Witczak, Marcin; Dziekan, L. (2012-03-01)
Restricted access - publisher's policyIn this paper, a Fault Tolerant Control (FTC) strategy for Linear Parameter Varying (LPV) systems that can be used in the case of actuator faults is proposed. The idea of this FTC method is to adapt the faulty plant instead ...
Luzar, Marcel; Witczak, Marcin; Buciakowski, Mariusz; Puig Cayuela, Vicenç (2013)
Restricted access - publisher's policyThe paper deals with the problem of robust faulttolerant control (FTC) for non-linear systems. Main part of this paper describes a robust fault detection, isolation and identification scheme, which is based on the observer ...
