Design of Fuzzy Rule Based Novel Sliding Mode Controller for Buck Converter

This paper presents a fuzzy sliding mode controller for the Buck converter by a novel method, the novel method considers system and designs the controller on the three-dimensional space, and thinks over the dynamic information of all elements in the buck circuit adequately. At the same time, the method adopts the exponent tendency arithmetic to descend chatter, and employs fuzzy theory to improve performance of the controller, the system can arrive the stability state further more quickly. Lastly this controller is applied on the Buck converter by the simulation experiments, and the result is excellent.
