Observer-based fault reconstruction for linear systems using adaptive sliding mode method

This paper studies the fault reconstruction problem for the continuous linear time-invariant system. A new disturbance-decoupled fault reconstruction design is proposed by cooperating with the idea of the adaptive sliding mode method. The new scheme does not impose restrictions on both the upper boundary of faults and the derivative of faults. Furthermore, the decoupling technique is used to deal with the disturbance input. Finally, simulation results are undertaken to validate the effectiveness of the proposed method
