Actuator multiplicative fault estimation in discrete-time LPV systems using switched observers
Rotondo, Damiano; López-Estrada, Francisco Ronay; Nejjari, Fatiha; Ponsart, Jean-Christophe; Theilliol, Didier; Puig, Vicenç (Journal article; Peer reviewed, 2016)This paper proposes an observer for the joint state and fault estimation devoted to discrete-time linear parameter varying (LPV) systems subject to actuator faults. The major contribution of this work is that the observer ... -
Detection of icing and actuators faults in the longitudinal dynamics of small UAVs using an LPV proportional integral unknown input observer
Rotondo, Damiano; Cristofaro, Andrea; Johansen, Tor Arne; Nejjari, Fatiha; Puig, Vicenç (Journal article; Peer reviewed, 2016)This paper proposes a linear parameter varying proportional integral unknown input observer (PI-UIO) for the diagnosis of actuator faults and icing in unmanned aerial vehicles. It is shown that in presence of sensor noise, ... -
Fault tolerant control of a proton exchange membrane fuel cell using Takagi–Sugeno virtual actuators
Rotondo, Damiano; Nejjari, Fatiha; Puig, Vicenç (Journal article, 2016)In this paper, a fault tolerant control (FTC) strategy for proton exchange membrane (PEM) fuel cells based on the use of virtual actuators and the Takagi–Sugeno (TS) approach is proposed. The overall solution relies on ... -
Robust fault and icing diagnosis in unmanned aerial vehicles using LPV interval observers
Rotondo, Damiano; Cristofaro, Andrea; Johansen, Tor Arne; Nejjari, Fatiha; Puig, Vicenç (Journal article; Peer reviewed, 2018)This paper proposes a linear parameter varying (LPV) interval unknown input observer for the robust fault diagnosis of actuator faults and ice accretion in unmanned aerial vehicles (UAVs) described by an uncertain model. ...
