A new approach for guaranteed state estimation by zonotopes

VTH Le, T Alamo, EF Camacho, C Stoica… - IFAC Proceedings …, 2011 - Elsevier
This paper proposes a methodology for guaranteed state estimation of linear discrete-time
systems in the presence of bounded disturbances and noises. This aims at computing an …

Robust fault detection with unknown-input interval observers using zonotopes

P Guerra, V Puig, M Witczak - IFAC Proceedings Volumes, 2008 - Elsevier
