[Industry research] A-VSC-HVDC-Fuzzy-Controller-to-Damp-Oscillation-o DL : 0: The fast control capability of the VSC-HVDC and the process of area mode oscillations are analyzed. An auxiliary fuzzy logic controller designed in Matlab for the Voltage Source Converter based HVDC transmission system, VSC-HVDC, to improve the stability of the AC/ DC system is designed to enhance stability by increasing the deceleration energy of oscillation. Simulation results on the IEEE 4-generator AC/DC power systems have shown that the controller can enhance the dynamic stability of interconnected power systems effectively and is robust to the variation of system operating conditions and oscillation modes.

[matlab] res DL : 1: Hybrid PV-wind generation shows higher availability as compared to PV or wind alone. For rural electrifications, researches are focused on hybrid power system which provides sustainable power. The variable voltage and frequency of the self excited induction generator (SEIG) is rectified through Vienna rectifier (three switches) to the required D.C voltage level and fed to common D.C bus. The variable output voltage of PV module is controlled by DC/DC converter using proposed fuzzy logic controller and fed to common D.C bus. The DC bus collects the total power from the wind and photovoltaic system and used to charge the battery as well as to supply the A.C loads through inverter. A dynamic mathematical model and MATLAB simulations for the entire scheme is presented. Results from the simulations and experimental tests bring out the suitability of the proposed hybrid scheme in remote areas.

[Other] Evaluation-of-Membership DL : 0: This paper investigates the effect of membership functions in the fuzzy control of a chopper fed dc drive. A Sugeno type fuzzy controller for closed loop control of dc drive fed by buck type dc-to-dc converter is designed and considered for evaluation. The controller is used to change the duty cycle of the converter and thereby, the voltage fed to the armature of the separately excited dc motor to regulate the speed. Sugeno type fuzzy controller is selected for evaluation, as it is easy to implement in any embedded microcontroller or DSP processor. The membership functions selected for evaluation are triangular, trapezoidal, Gaussian, bell shaped and PI functions. Above evaluation is done considering both five and seven linguistic sets for error and change in error. The results of the simulated performances are compared. The triangular membership function shows better performance compared to other membership functions

[Software Engineering] FUZZYPV4 DL : 0: Maximum power point tracking using a fuzzy logic control scheme.This paper proposes an intelligent control method for the maximum power point tracking (MPPT) of a photovoltaic system under variable temperature and insolation conditions. This method uses a fuzzy logic controller applied to a DC-DC converter device. The different steps of the design of this controller are presented together with its simulation. Results of this simulation are compared to those obtained by the perturbation and observation controller. They show that the fuzzy logic controller exhibits a much better behaviour.

[Software Engineering] APF thesis DL : 0: This thesis is a part of the research carried out on a double stage grid connected photovoltaic system, associated with a shunt active power filter. In the first stage, the photovoltaic generator is connected to a boost DC-DC converter, acting through two MPPT algorithms, based on fuzzy logic and sliding mode control, to track permanently the optimum point, and injecting so the extracted amount to the grid. In the second stage, a two-level voltage source inverter is introduced, to fulfill two main roles: Ensuring the injection into the grid of the extracted power, and acting as an active filter to eliminate the effect of undesirable harmonics, caused by the non-linear load. In this context, various techniques, inspired from the direct power control have been implemented to improve the energy quality of the system
