This paper describes the use of fuzzy logic to develop a simple and reliable maximum power point tracking (MPPT) technique for a stand-alone wind energy system. The system includes a wind turbine without the use of a gearbox, a permanent magnet synchronous generator (PMSG), a three-phase bridge rectifier and a DC-DC boost converter. The simulation results obtained by using MATLAB/Simulink show that...
This paper describes a current control of the three-phase inverter in a stand-alone wind energy system using model predictive control (MPC). The system includes a wind turbine without the use of a gearbox, a permanent magnet synchronous generator (PMSG), a pure diode based three-phase rectifier and a three-phase voltage-source two-level inverter. The simulation results obtained by using MATLAB/Simulink...
This paper discusses the coupling of two dimensional and one dimensional nano-materials to electromagnetic waves across the spectrum, from RF to light wave.
Today, despite of the development of various types of electric motors, the traditional DC motors are still widely used in robotic and industrial applications because this type of electric motors has a high control quality. Moreover, the DC motor drives are simple and easy for deploying novel control algorithms. This paper describes the steps of development of a fuzzy logic controller for the speed...
A face-naming method that learns from labeled and unlabeled examples relies on iterative label propagation in a graph of connected faces or name–face pairs.
