We consider a general class of hidden … Web— This paper investigates the unknown input observ-ability problem in the nonlinear case under the assumption that the unknown inputs are differentiable functions of time (up to a given order). The goal is not to design new observers but to provide simple analytic conditions in order to check the weak local observability of the state. The analysis starts …

The new definitions are applicable to a much broader family of … Web— This paper investigates the unknown input observ-ability problem in the nonlinear case under the assumption that the unknown inputs are differentiable functions of time (up to a …
WebAbstract. Nonlinear adaptive observers that do not require knowledge of the dynamics of the system being observed are proposed. This objective is pursued by envisioning a linear-in-parameters adaptive law that allows one to estimate the system dynamics, which are assumed to be in observability canonical form, just from measurements of the output.
