Second order sliding mode control for a class of underactuated systems

摘要

This paper presents a second order sliding mode control for a class of underactuated systems. Container motion coupled with slosh which represents a class of underactuated systems is sought. A stable sliding surface is designed to ensure asymptotic convergence of all the states. A second order twisting algorithm is used to synthesize a smooth control to ensure finite time convergence of the sliding. The proposed method is validated in simulation.
