Sensor Fault Identification in Mechatronic Systems Described by Linear and Nonlinear Models

The problem of sensor fault identification in mechatronic systems described by linear and nonlinear dynamic models is considered. To address the problem, sliding mode observers are used. The suggested approach for constructing sliding mode observers is based on the reduced order model of the initial system. This allows to reduce complexity of sliding mode observers and relax the limitations imposed on the initial system.
