Non-smooth control-based reaching law for discrete-time sliding mode control

This paper employs non-smooth control method to propose a new chattering-free reaching law for discrete-time sliding mode control (DSMC). It is shown that the newly non-smooth control-based DSMC can guarantee that not only the same level of accuracy for the sliding mode motion as that of an equivalent control-based DSMC but also no need for an overly large control effort. To show the effectiveness of the proposed approach, a simulation example is given.
