Description: 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. Platform: |

Description: A hybrid fuzzy-PI controller for voltage source
converter based HVDC (VSC-HVDC) transmission system is
proposed in this paper. At first, the elementary model of VSCHVDC
is described. Then the fuzzy self-tuning control strategy is
proposed, in which direct current control strategy and dual
closed loop structure are designed in dq synchronous reference
frame. Independent control of the active and reactive power is
realized. Simulation results show that the designed control system
obtains satisfying performance, and the adjustments of power
flow could be achieved quicker than convention PI control. Platform: |

Description: 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. Platform: |

Description: 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 Platform: |

Description: 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. Platform: |
