Unknown inputs observers for a class of nonlinear systems

Abstract

A high gain observer is proposed for a class of multi-output nonlinear systems with unknown inputs in order to simultaneously estimate the whole state as well as the unknown inputs. The gain of this observer does not require the resolution of any dynamical system and is explicitly given. Moreover, its tuning is reduced to the choice of two real numbers. The performances of the proposed observer are demonstrated in simulation through an illustrative example
