چکیده

Abstract:


Direct torque and flux control (DTFC) is known for its reduced torque and flux ripples compared to the classical direct torque control scheme. It can drive an interior permanent magnet synchronous motor (IPMSM) in usual control regimes while satisfying current and voltage limits of the system. However, deep flux-weakening control of an IPMSM under DTFC has not been investigated as extensively, especially operation along the maximum torque per voltage (MTPV) trajectory in the torqueflux plane. This study proposes a simple and effective control method, which incorporates MTPV trajectory in the conventional flux-weakening algorithm of DTFC. Performance of an IPMSM drive is analysed when operated with the proposed control method.

5 Conclusion


In this paper, wide-speed operation of a direct torque and flux controlled IPMSM drive was discussed. For a wide speed range, the MTPV trajectory which delivers the optimum performance by minimising flux for maximum torque can be incorporated in the conventional trajectory control of DTFC. It was observed that the load angle of an IPMSM can be indirectly controlled by operating along the trajectories defined on T–λ plane. The operation along MTPV trajectory under DTFC can extend the motor speed to the deep flux-weakening region without violating the maximum load angle condition.
