| Popis: | Trabajo presentado a la 15th European Control Conference (ECC) celebrada en Aalborg (Dinamarca) del 29 de junio al 1 de julio de 2016. This paper presents the analysis and comparison of interval-observer-based and set-membership approaches for the state estimation of linear uncertain systems. In both approaches noise and disturbances are assumed to be unknown but bounded. In this paper, both approaches are compared when implemented using zonotopes. Mathematical expressions of both approaches are compared and conditions under which they provide the same state estimation are derived. At the end, an example based on a two-tanks system is used to test the obtained conditions. This work has been partially funded by the Spanish Ministry of Science and Technology through the Project ECOCIS (Ref. DPI2013-48243-C2-1-R). |
