The basic issues related to the digital field-oriented control of dual three-phase induction motor drives were addressed in the paper. It has been demonstrated the feasibility of vector controlled multi-phase induction motor drives for some specific industrial applications, such as low voltage/high current applications.
By choosing the implementation of PI controllers in the stator flux synchronous reference frame, the d-axis controller regulates the stator flux, while the q-axis controller regulates the torque by means of the q-axis stator current. The experimental results demonstrate the feasibility of the proposed solution for direct stator flux and torque control.
