In this paper, a frequency-shaped optimal sliding mode approach combined with Lyapunov based backstepping design is presented to solve the robust servomechanism problem. The parametric uncertainties, unmodeled dynamics and uncertain exogenous disturbance belonging to a specified class are attenuated by using compensator dynamics introduced in sliding mode through an augmented dynamic sliding surface. ©2006 IEEE.
