摘要：Abstract: The persistence of excitation of signals generated by time-invariant, continuous-time, autonomous linear and nonlinear systems is studied. The notion of persistence of excitation is characterised as a rank condition which is reminiscent of a geometric condition used to study the reachability properties of a control system. The notions and tools introduced are illustrated by means of simple examples and of an application in system identification.
