| Abstract: |
| Past permanent magnet synchronous motor using hexagonal flux control or six intervals flux control interval which results in torque ripple and other shortcomings. In this paper, the dual controller permanent magnet synchronous motor direct torque control system based on vector subdivision is designed. This design of the vector control strategy is to segment the six voltage vector in tradition and is subdivided into six sectors flux multiple voltage vector and flux sector, and appropriate switch table is developed. Matlab simulation results prove that permanent magnet synchronous motor direct torque control strategy based on vector subdivision is feasible. |
