Abstract

A feedback control methodology is presented for online approximation based backstepping control of non-linear dynamical systems subject to magnitude, rate, and bandwidth constraints on the state and the actuators. The robustness issue with respect to functional approximation errors is addressed in a rigorous manner. The stability properties of the proposed design methodology are derived.
