    The 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 ...
  • Development of a Fault-Tolerant Control with MATLAB and its application to the Twin-Rotor System 

    Luzar, Marcel; Witczak, Marcin; Puig Cayuela, Vicenç; Nejjari Akhi-Elarab, Fatiha (2009-11-19)
    Conference report
    Open Access
    The 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

    In 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 ...
  • Predictive fault tolerant control for LPV systems using model reference 

    Acevedo Valle, Juan Manuel; Puig Cayuela, Vicenç; Tornil Sin, Sebastián; Witczak, Marcin; Rotondo, Damiano (International Federation of Automatic Control (IFAC), 2015)
    Conference report
    Open Access
    The present work proposes a Fault Tolerant Control (FTC) methodology for non-linear discrete-time systems that can be modeled as Linear Parameter Varying (LPV) systems. The proposed approach relies on the modeling of faults ...
