直接トルク制御を用いたIPMSM駆動システムの運転領域拡大のための指令値計算法の比較

抄録

Maximum torque per flux control strategy used for high-speed operations causes instability in direct-torque-controlled IPMSM drives. Therefore, some reference calculation methods in direct torque control have been reported for high-speed operations. This paper compares the features of controls using each calculation method and considers the influence of inductance variation in simulations and experiments.
