A DSP-based vector control of multiphase induction machine

This paper presents the mathematical model of multiphase induction machines in the synchronous reference frame by using generalized two axis real transformation, which simplifies the modeling and control of multiphase induction machines. A detailed implementation of an indirect type multiphase induction machine rotor flux field orientation control and unified PWM technique applied to the multiphase inverter are described. The control method is implemented on the floating-point DSP board TMS320C32 to verify the validity of the developed control strategy.
