Abstract :
A new notion of detectability for nonlinear systems, which generalizes the existing definition of detectability for linear systems, is explored. Based on this notion, a constructive observer design method for detectable, but not necessarily observable, nonlinear systems is given. Preliminary results on the observer design for “poorly observable” systems are also discussed and illustrated with an example
