Observer-based robust switched dynamic output control

الملخص EN

This paper discusses the stabilization of discrete time, polytypic uncertain switched systems focusing on the design of a robust dynamic output feedback control, based on a luenberger observer's.

The results are derived using the direct lyapunov approach and the polyquadratic function concept.

The stabilization conditions are written through linear matrix inequalities relation.

The polyquadratic lyapunov approach provides a constructive way to tackle uncertainty in the switched framework.

The feasibility is illustrated on an example of discrete time uncertain switched systems, when one of used actuators broke down.
