Abstract

Robust parametric control theory is a powerful tool for the research of linear control systems robustness against simultaneous changes in the parameters that define the plant and controller transfer functions. The purpose of this paper is to show how those techniques can be applied to the sensitivity study of DC-DC power converters control loops with respect to simultaneous variations of all the parameters defining the power stage: line voltage, load, and passive elements of the power stage
