Abstract

BERZOY-LLERENA, Alberto et al. Fuzzy control techniques applied to a three phase synchronous rectifier current loop. Rev.fac.ing.univ. Antioquia [online]. 2015, n.74, pp.23-36. ISSN 0120-6230.

This work presents three fuzzy variable structure control (FVSC) techniques applied to the current control loop in a three-phase synchronous rectifier. These techniques are based in a Takagi-Sugeno (T-S) fuzzy PI controller. The first controller is a first-order FVSC, used as a reference. Then, two FVSC strategies are presented and tested, a second and a third-order FVSC. These control schemes are first simulated and then tested in a general-purpose laboratory synchronous rectifier test bench. Experimental results show that control performance is good in all three schemes, achieving current harmonic compensation and power factor correction.

Keywords : FIS Takagi-Sugeno; fuzzy control; three phase synchronous rectifier control; power factor correction.
