Abstract :
In this paper, a new adaptive variable structure control (VSC) scheme is proposed for nonlinear systems without a prior knowledge of control directions. By incorporating a Nussbaum-type function, the new adaptive VSC law can ensure the asymptotic convergence of the tracking error in the existence of non-parametric uncertainties. Simulation results are shown to validate the effectiveness of the proposed control scheme.
