Nonlinear stabilizing control design for DC-DC converters using lifted models
Nonlinear stabilizing control design for DC-DC converters using lifted models
This article contains a novel approach to dc-dc converter nonlinear control design, working on continuous conduction mode. In particular, the problem of instability induced by constant power loads is addressed. The proposed setting is based on the use of lifted models in terms of power and energy, obtained from voltage/current observable nonlinear transformations. We show that stability can be imposed on lifted models via control design in a much more direct fashion than in traditional current/voltage coordinates. To illustrate the versatility of this approach, we propose three different nonlinear controllers with stabilization capabilities, which exploit the advantages of lifted dynamics in a different way. These strategies are experimentally validated and tested under abrupt and intermittent input voltage and load variations.

Abstract
This article contains a novel approach to dc-dc converter nonlinear control design, working on continuous conduction mode. In particular, the problem of instability induced by constant power loads is addressed. The proposed setting is based on the use of lifted models in terms of power and energy, obtained from voltage/current observable nonlinear transformations. We show that stability can be imposed on lifted models via control design in a much more direct fashion than in traditional current/voltage coordinates. To illustrate the versatility of this approach, we propose three different nonlinear controllers with stabilization capabilities, which exploit the advantages of lifted dynamics in a different way. These strategies are experimentally validated and tested under abrupt and intermittent input voltage and load variations.
