This work deals with the control of an uncertain nonlinear second order servomechanism under influence of measurement noise. Stability analysis for the closed-loop system is carried out by Lyapunov’s second method. The loop has been closed applying a Proportional-Derivative controller with uncertainty compensation to the servo. Such a controller employs estimates obtained from an Integral High Gain Observer. Real-time experiments for path tracking task have been performed on a laboratory prototype to validate the proposed approach.
