Abstract

This paper is dedicated to the identification of parameters for a reasonably large class of nonlinear systems. We propose to design a direct parameter identification method in open loop and an indirect one in closed loop using the variable structure theory. The exponential convergence of parameter identifiers in both cases is studied. Finally, we highlight some robustness properties of the method with respect to bounded parameter perturbations.
