| Abstract |
This paper proposes a novel method of maximum power operation for permanent magnet synchronous motors in a direct torque control system. Torque limiting satisfying current limiting is based on the power equation instead of the motor model in the rotating d-q frame, which is synchronized to the rotor magnet. This method of torque limiting does not require the motor parameters to be determined and simplifies calculation for the limitation. The proposed method incorporates flux-weakening control that does not require motor parameters other than the armature resistance to be determined. The proposed motor drive system can achieve stable control and control that is not sensitive to parameter variation. The proposed method is validated through simulation and experimentally. |
