Virtual Signal Injected MTPA Control for DTC Five-Phase IPMSM Drives

다국어 초록 (Multilingual Abstract)

This paper introduces a virtual signal injected maximum torque per ampere (MTPA) control strategy for direct-torquecontrolledfive-phase interior permanent magnet synchronous motor (IPMSM) drives. The key of the proposed method is that ahigh frequency signal is injected virtually into the stator flux linkage. Then the responding stator current is calculated andregulated to compensate the amplitude of the flux linkage. This is done according to the relationship between the stator currentand the stator flux linkage. Since the proposed method does not inject any real signals into the motor, it does not cause any of theproblems associated with high-frequency signals, such as additional copper loss and extra torque ripple. Simulation andexperimental results are offered to verify the effectiveness of the proposed method.
