The application like electric vehicles requires frequent torque control to control speed of IM Drives. The direct torque control is very good control scheme for fast torque control and it is easy to implement and decoupling of motor variables along rotor flux axis is not required. In this paper, direct torque control scheme is proposed using 12-sided polygonal space vector based inverter fed IM drive...
This paper proposes a sensorless vector control scheme for general-purpose induction motor drives using the current error space phasor-based hysteresis controller. In this paper, a new technique for sensorless operation is developed to estimate rotor voltage and hence rotor flux position using the stator current error during zero-voltage space vectors. It gives a comparable performance with the vector...
This paper proposes a simple current error space vector based hysteresis controller for two-level inverter fed Induction Motor (IM) drives. This proposed hysteresis controller retains all advantages of conventional current error space vector based hysteresis controllers like fast dynamic response, simple to implement, adjacent voltage vector switching etc. The additional advantage of this proposed...
