Abstract :
This paper describes a design method for robust control of dc-dc switched converters using quantitative feedback theory (QFT). The chief advantage of this approach is that the method takes into account plant uncertainties from a frequency point of view in a systematic way. This clarifies how the design can fulfil the requirements, simplifying the designer´s task
