Abstract

The aim of this paper is the synthesis of a robust control law for regulation control of a class of relative-degree one non-linear systems. The control design is based on sliding-mode uncertainty estimator, developed under the framework of algebraic-differential concepts. The closed-loop stability for the underlying closed-loop system is done via averaging techniques. Robustness of the proposed control scheme is proved in the face of noise measurements, model uncertainties and sustained disturbances. The performance of the proposed control law is illustrated with numerical simulations
