Sampled-data control with adjustable switching frequency for DC-DC converters
Sampled-data control with adjustable switching frequency for DC-DC converters
In this paper, a novel sampled-data control approach is proposed for DC-DC converters. The DC-DC power electronic converter is modeled as a sampled-data switched affine systems according to the status of the power switch. A novel switching control algorithm is synthesized by using the switched Lyapunov theory. The proposed approach is able to not only drive the output to a prescribed set point from any initial condition but also track a varying reference signal, and the switching frequency can be adjusted online with guaranteed stability. In addition, with this approach, CCM and DCM operations can be treated in a unified way. The effectiveness and merits of the proposed method are illustrated by experiments on a laboratory prototype.

Abstract
In this paper, a novel sampled-data control approach is proposed for DC-DC converters. The DC-DC power electronic converter is modeled as a sampled-data switched affine systems according to the status of the power switch. A novel switching control algorithm is synthesized by using the switched Lyapunov theory. The proposed approach is able to not only drive the output to a prescribed set point from any initial condition but also track a varying reference signal, and the switching frequency can be adjusted online with guaranteed stability. In addition, with this approach, CCM and DCM operations can be treated in a unified way. The effectiveness and merits of the proposed method are illustrated by experiments on a laboratory prototype.
