  • Abstract
    A nonlinear control is proposed and its application to the regulation of the dc-dc converters of the boost and buck types is investigated. The proposed controller, which assumes the exponential form of the linear multiloop controller, provides an additional tuning parameter which can used to modify the output response. The system stability in the presence of uncertain load and line voltage as well as the relationship between the nonlinear and linear control strategies are studied. Numerical and experimental results to illustrate the features of the proposed strategy are also presented
