Abstract
An induction motor torque control system is provided for resolving an excitation current command and a secondary current command into an excitation flux vector component and electromotive force-direction (torque direction) vector component, respectively, based on a torque command for the motor and an excitation flux command, decided for the motor, in such a manner that a linear output torque is obtained in response to these commands. A primary current command for the motor is obtained by combining these vector values.
