Abstract

The modelling and adaptive sliding-mode control of a high-order buck-boost converter is presented. The converter gives a high voltage gain and presents low current stress on its circuit components. The full-order model of the converter is derived by using a combination of the averaged state-space modeling approach and a duty ratio constraint deriving method. An adaptive sliding-mode controller for this converter is then proposed in which the adaptive law calculates the estimated load conductance to generate the required sliding surface. The stability analysis of the adaptive sliding-mode controlled system is performed. In addition, experimental results comparing the performance of the proposed adaptive sliding-mode controller with that of an existing robust sliding-mode controller are provided to present the advantages.
