摘要：
Useful fault information, such as the amplitude and the sign, occurring during a time variable dynamic process are of capital importance to proceed correctly to fault compensation. The existing observers in literature, providing residues signals containing information on the presence or not of faults, do not take into account all of the faults when those occur at very close moments, which leads to an incorrect eventual compensation. This consideration is very significant for a correct dynamic control. In this paper, the characterization of the fault form in the time varying dynamic systems based on observers is proceeded to consider the detection of several faults some is their incidence moment and to take into account their amplitudes. The study of the several faults succession at these resolution in precise fault detection is shown.
