Métodos de Projeto de Controladores de Tensão Aplicados a Fonte Ininterrupta de Energia

Abstract

This work proposes different design methodologies for resonant controllers applied to static power converters focusing on an uninterrupted power supply. Three methods of resonant control are analyzed, the first is considering the internal model, the second is through state feedback and the third is applying the DQ transform. The performance of each controller is tested considering load variation, certifying the robustness against parametric uncertainties. All methods presented satisfactory results, and the internal model resonant controller obtained the best error tracking.
