Abstract

A robust higher order sliding mode algorithm combining the merits of the modified super-twisting algorithm and the adaptive super-twisting algorithm has been proposed for a class of nonlinear uncertain systems in this article. For a class of linearly growing perturbations whose upper bounds are not known, the convergence of the sliding dynamics in finite time is proven. To illustrate the effectiveness of the proposed approach, an adaptive robust controller based on the proposed algorithm is developed for the nonlinear active suspension system faced with perturbations from the road surface. Simulation results provided demonstrate the effectiveness of the proposed approach.
