Rapid control prototyping of fifteen-phase induction motor drives based on dSPACE

This paper introduces an H-bridge VSI inverter for the fifteen-phase induction motor. The systempsilas controller is based on the dSPACE real-time system. PWM generator module is based on the FPGA system which is interfaced with the dSPACE prototyping board DS4201. The control strategy in the Simulink is designed which considers the third harmonic component injection in the stator voltage. Combining with the Real-Time Interface (RTI) and Real-Time Workshop (RTW), dSPACE can realize the real-time C code auto generating from the Simulink model to the real-time processor. User interface based on the ControlDesk is also developed. Finally, the experiment results verified the feasibility and the correctness of control scheme.
