Title: Robust fault estimation observer design with finite-time convergence specification
Authors: Ke Zhang;Bin Jiang;Vincent Cocquempot
Year: 2017
Publisher: IET
Abstract: In this study, the problem of fault estimation observer design with finite-time convergence specification for continuous-time dynamic systems subject to external disturbances. First, the unknown input observer is constructed to achieve accurate estimation of the occurred fault and to guarantee robustness against the disturbance. Then a pole placement-based fault estimation observer is constructed using time-delay design such that the fault estimation error converges to zero in finite time. Unlike conventional literatures, the proposed fault estimator with finite-time convergence specification does not contain discontinuous sign function. Finally, simulation results of an aircraft application are presented to illustrate the finite-time convergence of the proposed fault estimation observer.
