Abstract: This paper proposes a novel discrete-time sliding mode (DTSM) control approach to address the robust stability problem of buck converters with multiple disturbances. The contributions lie in the “unified” modelling and controller design. In modelling, all the possible model uncertainties and external disturbances are considered and further classified into two cases. It can also be extended to the situations with individual/several disturbances. While for the controller design, differing from the traditional DT… Show more

“…As a kind of DC-DC power converter, the buck type has been widely used in various fields, due to its simple circuit topology, high efficiency and reliability [1,2]. Since buck converters generally consist of such components as the inductor, capacitor, diode and power switches (e.g., IGBT, MOSFET), they are characterized by time-varying nonlinearity.…”

“…However, attention should be paid to the fact that there might be individual, several, or all disturbances, in practice. A unified disturbance classification could be referred to [2], which was determined by whether the input lumped disturbance β 3 existed or not. Therefore, a unified robust controller was necessary.…”
