On nonlinear detectability

It is shown that the steady state property of the unobservable part of a given nonlinear dynamics is equivalent, under some boundedness assumptions, to the existence of a state detector (detectability). This property is illustrated, discussed and related to the existence of partial observers; local...

Description
Summary:It is shown that the steady state property of the unobservable part of a given nonlinear dynamics is equivalent, under some boundedness assumptions, to the existence of a state detector (detectability). This property is illustrated, discussed and related to the existence of partial observers; local and global aspects are considered.
