One of the most important control methods in induction motor is direct vector control. This method is based on rotor flux estimation using stator voltage. The machine voltage is low in The voltage model for low speed and voltage drop over the stator resistance is not negligible in front of stator voltage. Thus the stator flux estimation using voltage method is not precise. Some methods are base...
In this study, direct torque control (DTC) of induction motor is evaluated based on space vector modulation (SVM).DTC is a method to control machine with utilizing torque and flux of motor controlled.Direct Torque Control (DTC) is known to produce fast response and robust control in ac adjustable speed drives. However, in the steady-state operation, notable torque, flux and current pulsations o...
This paper presents a hybrid scheme for the control of active and reactive powers using the direct vector control with stator flux orientation (SFO) of the DFIG. The hybrid scheme consists of Fuzzy logic, Reference Signal Tracking (F-RST) controllers. The proposed (F-RST) controller is compared with the classical Proportional-Integral (PI) and the Polynomial (RST) based on the pole placement th...
