In this paper we study the problem of controlling uncertain nonlinear systems. The uncertainty is considered to be dynamic and additive, and the nominal system is assumed to be feedback-linearizable. It is shown that the state of the uncertain nonlinear system may be stabilized using a controller designed for the nominal system. It is also shown that the conditions for stability depend on the size of the uncertain terms.
