Unknown input observer: a physical approach
Authors: Dapeng Yang, Christophe Sueur
Abstract
? The object of this paper is the study of a new unknown input observer for linear models. This new observer has some classical restrictive conditions proposed for other ones infinite structure condition and Hurwitz conditions for invariant zeros. The main contribution are twofold this new observer has the same state space representation as the initial state model and it is shown to be very accurate. Simulation results are proposed for a DC motor example with analysis of two other classical methodologies.
