Abstract :
Based on strict matching conditions and a linear parameterization assumption, a certainty equivalence control law to pseudolinearize nonlinear systems in the presence of parametric uncertainty is designed. Stability of the origin and state regulation are guaranteed in the vicinity of any equilibrium point of the nonlinear system. These are the first results reported for the pseudolinearization of a class of nonlinear systems with uncertain parameter knowledge.<>
