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 ...
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. ...
