Abstract
This paper addresses an adjustable parameter (AP)-based multi-objective fault estimation design forcontinuous-time/discrete-time dynamic systems. First, a fault estimation observer with AP is constructed to on-lineidentify the size of occurred faults. The fault estimation design not only possesses a wider application comparedwith adaptive observers, but also uses the current output information to enhance fault estimation performance. Then a multi-objective approach is proposed to determine the gain matrices of fault estimation observer. Moreover,fault estimation results with the slack-variable technique are obtained to further reduce the conservatism. Finally,simulation results of an aircraft application are presented to illustrate the effectiveness of our contribution.
