In this paper, a system, which is subject to perturbations and unknowns, with a saturating actuator is considered. In order to design a robust feedback control law based on the sliding mode approach, the standard super-twisting algorithm is modified adopting an anti-windup technique. Similar to the conventional super-twisting controller, the control signal introduced into the system is continuous everywhere. The performance of the conventional one is, however, significantly improved in the case that the initial condition of the system is far away from the origin. Global finite-time stability properties of the closed-loop are investigated, which gives a parameter setting for the controller. Having employed numerical simulations, feasibility and effectiveness of the scheme are indicated.
