Direct Torque Control (DTC) is a method, which is used to control the flux and torque of a motor. This method uses a flux and torque estimator and two hysteresis controllers. The major problem that is usually associated with DTC drive is the high torque ripple. The stator resistance is used in the flux and torque estimator. So the stator resistance deviation from its set value, might affect fuzzy-DTC...
The active power filter has been proved to be an effective method to mitigate harmonic currents generated by nonlinear loads as well as to compensate reactive power. The main objective of this work is to develop a new control strategy to improve the performances of shunt active power filter for mitigating current harmonics under balanced and unbalanced sinusoidal source voltage conditions. To achieve...
Wind energy features prominently as a supplementary energy booster since the wind speed varies. Evaluation of control schemes for electrical generator is hard with wind turbine. For similar environment of turbine, a wind turbine emulator (WTE) is used. The purpose of systems is to maximize energy efficiency, and extract maximum power from the wind speed. In This case, the MPPT control becomes important...
