Abstract
A high gain observer is proposed for a class of multi-outputnonlinear systems with unknown inputs in order to simultaneouslyestimate the whole state as well as the unknown inputs. The gainof this observer does not require the resolution of any dynamicalsystem and is analytically given. Moreover, its tuning is reducedto the choice of two real numbers. The performances of theproposed observer are demonstrated in simulation through anillustrative example.
