$H_\infty$ generalized dynamic observer for LPV singular system
Résumé
The present paper considers the H-infinity observers design for linear parameter varying (LPV) singular systems by introducing a new observer structure named generalized dynamic observer (GDO), which is more general that the proportional observer (PO) and the proportional-integral observer (PIO). The objective is to design a GDO such that the resulting error dynamics is stable and a given level of disturbance attenuation is assured. The stability conditions for the existence of this H-infinity GDO are given in terms of a set of linear matrix inequalities (LMIs). A numerical example is given to show the present approach.
