Abstract
In this paper state observers for control systems with nonlinear outputs are studied. For such systems, the observability does not only depend on the initial conditions, but also on the exciting control used. In this paper some sufficient conditions are given for the convergence of an observer. It is also discussed, via a vision example, how to actively excite the system in order to improve the observability
