Abstract
The observability properties of nonlinear systems with unknown inputs are characterized via differentially algebraic techniques. State variables and unknown inputs are estimated thanks to a new algebraic numerical differentiator. It is shown through an academic example and a concrete case-study that the proposed scheme can be applied to systems that fail to fulfill some usual structural assumptions.
