A hybrid sliding mode control strategy for a class of second order systems is presented in this paper. It is characterized by an event-driven gain reduction mechanism relying on a decomposition of the system state into regions. By enforcing sliding mode behaviors on a suitable set of sliding manifolds, while avoiding the generation of limit cycles, the proposed strategy proves to globally asymptotically stabilize the origin of the system state space.
