Abstract
A novel input-output approach to the problem of robust state estimation in the presence of model uncertainty as well as plant disturbance and sensor noise is considered. A new observer structure is introduced and shown to have advantages over the classical Luenberger observer. This structure is then used to solve the robust estimation problem in the H∞ framework
