Abstract :
In this paper parameter space and Lebesgue measurement are introduced into analysis of nonlinear systems.Structural observability rank condition is defined and together with the distinguishabililty the structural observability of nonlinear systems is obtained.It proves that when the parameters are not identifiable the solutions with the same time but different parameters are also indistinguishable. Examples are used to illustrate applications of the structural observability criterion.
