Discrete sliding mode control of a boost converter for output voltage tracking

This paper proposes the design of a discrete sliding control of a boost DC-DC power converter for the output tracking of a sinusoidal reference signal. The discrete sliding surface is designed by imposing a desired dynamic behavior on the system, which allows to determine the main parameters of the sliding mode controller. This procedure leads to a discrete-time switching surface, which provides robustness with regards to external disturbances and a good dynamic response of the output voltage.
