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