Observer-based actuator and sensor fault estimation
Authors: Christophe Sueur
Abstract
A simple and straightforward unknown input observer with application to process fault estimation is presented. The observer information is devoted to the fault estimation for fault detection and isolation but it can be used to form an additional control input to accommodate the fault, since an estimated state vector is also obtained. An extension to fault sensor is discussed. The scheme is verified through simulation studies performed on the control of a vertical takeoff and landing aircraft in the vertical plane..
