Hysteresis Vector Controller For Three Phase Induction Motor

Abstract-The magnitude and orientation of the stator flux must be known in order to directly control the stator flux by selecting appropriate voltage vector. The stator flux plane is divided into six sectors. Each sector has a different set of voltage vectors to increase voltage vector highlighted in gray or decrease voltage vector highlighted in black the stator flux . The stator flux is forced to follow the reference value within a hysteresis band by using a 2-level hysteresis comparator. If the stator flux lies in sector k then the voltage vector selected to increase the stator flux and selected to decrease the stator flux. In This Paper we are controlling torque or speed of three phase induction motor with concept hysteresis vector controller and we have designed hysteresis vector controller on Matlab Simulink tool which is the advancement in classical DTC model for induction motor.
