Description
Abstract:	In this paper, we show that, for certain identification problems arising in connection with Hamiltonian, tracking control, the regressor vector constructed out of radial-basis-function approximants will be persistently excited, provided a kind of "ergodic" condition is satisfied. In addition, we will provide bounds on the exponential convergence rates associated with the persistently excited regressor vector.
