The torque of the induction motor control apparatus and method for directly

摘要

The present invention relates to a method comprising direct torque control apparatus and method of the induction motor, the normalized magnitude of the error between the stator flux and stator flux reference won; Comprising a dimensionless magnitude of the error between the motor torque and the reference torque; Obtaining a phase angle of the stator voltage vector from the stator flux of the dimensionless error and the dimensionless torque error; And determining the magnitude of the stator voltage vector from the angular velocity of the synchronous motor; including, provides a torque control device and method of an induction motor that can directly reduce the stator flux and torque error error at the same time. ; Direct torque control, space vector modulation, the torque ripple reduction, reduced stator flux ripple
