| Abstract: | The mathematical model of permanent magnet synchronous motor (PMSM) in the rotor reference d-q frame is puts forward at first. Then the DTC theory of PMSM and the voltage vector table are analyzed. A new DTC scheme for PMSM is proposed in this paper, which is based on the area voltage vector. And the paper offers the available modulation algorithm between torque and flux. By the theory analysis and simulation based on MatLab 6.5/Simulink, it is proved that the proposed strategy enables to diminish the torque ripple, especially in low speed range. In addition, both the precision of control and high dynamic performance are achieved. |
