Abstract
We consider here the problem of state and input estimation for a class of uncertain systems which consist of a nominally linear part and an uncertain/nonlinear/time-varying part which can be regarded as a state -dependent/time-varying input. We obtain a Lyapunov-type characterizat ion of the assumptions commonly found in the literature on this proble m. Using this characterization, we obtain estimators which, using only a measured output, can asymptotically estimate to any desired accurac y the system state and the input.
