Discrete-time terminal sliding mode controller based on input-output model

In this paper, a discrete terminal sliding mode controller (DTSMC) is proposed based on a new nonlinear sliding function. This strategy of control is developed using only the input-output (I/O) model. To improve the effectiveness of DTSMC, we applied it to a DC-DC buck converter. The results obtained by simulations are given at the end to demonstrate the effectiveness of our proposed scheme in terms of fast convergence speed and robustness against disturbances.
