Application of fuzzy decision making to the switching state selection in the predictive control of a Direct Matrix Converter

摘要: The finite states model predictive control is a promising alternative in the field of power converters. Its characteristics allow simple and flexible schemes with fast dynamics. However, standard formulation this type controllers, which based on an aggregated cost function, requires suitable weighting factors for adequate switching state selection. specification these depend various parameters making it non trivial process. In work, proposed that replaces function fuzzy decision strategy. This strategy retains multiple attribute nature As result, possibility more natural higher level design approach to selection process opened. To introduce technique, only objectives equal importance are considered. Simulation results presented illustrate validate using output input currents Direct Matrix Converter.
