This paper studies the problem of fault estimation of neutral delay systems using adaptive observer.A novel fast adaptive fault estimation (FAFE) algorithm based on adaptive observer is first proposed to enhance the performance of fault estimation including rapidity and accuracy.Meanwhile,a delay-dependent criterion is established to reduce the conservatism of design procedures especially for small delay systems.Then,comprehensive analysis is presented to discuss the calculating steps using linear matrix inequality (LMI) technique.Finally,simulation results are presented to illustrate the efficiency of the proposed algorithm.
