Research on Direct Torque Control of Permanent Magnet Synchronous Motor Based on Matlab Simulation |
| |
| Abstract: | Permanent magnet synchronous motor （PMSM） belong to a kind of strong coupled nonlinear system. The speed-adjusting problem of PMSM was discussed, which is considering the characteristics of PMSM and combining direct torque control （DTC） method together. According to the theory of motor, the maths model of PMSM is set up under rotor coordinate first in the article. Then the principle of DTC method is raised based on PMSM. Simulation results indicate that the system not only has higher dynamic performance, but also improves the adaptability for different reference speed. |
