Abstract
This paper deals with the torque control of five-phase permanent magnet synchronous machines with first and third harmonics injection. A new vectorial approach to describe the voltage and current limits is proposed. Starting from the transformed dynamic equations and using the voltage and current constraints, the optimal current references minimizing the dissipation and maximizing the torque is obtained. The proposed control law holds for an arbitrary shape of the rotor flux. Some simulation results validate the proposed control law.
