Abstract
This paper presents a new control strategy based on the sliding mode control theory. The controller is designed so that the state trajectories of a plant will stay close to a switching surface in a certain future time, not stay on it at the present time. To this end, the future value of the switching function is evaluated with the prediction of the plant state and disturbances. As a result, a discontinuous input with a time-varying gain, which is adjusted in every prediction interval based on prediction is introduced.
