Abstract :
In this paper it is shown how to design nonlinear observers that achieve global exponential convergence for the error dynamics for a class of nonlinear systems, namely nonlinear systems that are homogeneous of order 0 with respect to an arbitrary integer dilation. The proposed technique is based on immersion into a higher dimensional linear system.
