The dead-zone is one of the most common hard nonlinearities in industrialactuators and its presence may drastically compromise control systems stabilityand performance. In this work, an adaptive variable structure controller isproposed to deal with a class of uncertain nonlinear systems subject to anon-symmetric dead-zone input. The adopted approach is primarily based on thesliding mode control methodology but enhanced by an adaptive fuzzy algorithm tocompensate the dead-zone. Using Lyapunov stability theory and Barbalat's lemma,the convergence properties of the closed-loop system are analytically proven.In order to illustrate the controller design methodology, an application of theproposed scheme to an electro-hydraulic system is introduced. The performanceof the control system is evaluated by means of numerical simulations.
