Method of sensor fault identification based on higher-order sliding mode observers

The problem of sensor fault identification in technical systems described by linear equations under the external disturbances is studied. To solve the problem, sliding mode observer is used which is constructed based on the reduced-order model of the initial system. This model is sensitive to the faults and insensitive to the disturbances. It is shown that if some conditions are met, then sliding mode exists which allows obtaining exact estimation of the fault.
