Exact fault reconstruction for uncertain linear systems based on sliding mode observer

الملخص EN

This paper proposes a robust sliding mode observer for a class of linear uncertain systems to generate a reconstruction of faults.

The state estimation error of the proposed observer is shown to be uniformly ultimately bounded with respect to a ball whose radius is a function of design parameters.

An exact fault reconstruction scheme that is decoupled from the uncertainty is presented.

In simulation, a real model of VTOL aircraft is used to illustrate the effectiveness of the work of this paper.
