Fuzzy control techniques applied to a three phase synchronous rectifier current loop
Journal Title: Revista Facultad de Ingeniería-Universidad de Antioquia - Year 2015, Vol 1, Issue 74
Abstract
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.

Low complexity demodulator for BFSK waveforms based on polygonal approximation
The present article relates in general to digital demodulation of Binary Frequency Shift Keying (BFSK waveform). New processing methods for demodulating BFSK-signals are proposed here through the use of segmentation curv...

Parameter estimation method for induction machines using instantaneous voltage and current measurements
This paper proposes an off-line method to determine the electrical parameters of an induction machine based on two instantaneous indicators (impedance and power). The method uses the induction machine start-up voltage an...
