基于模糊控制永磁同步电机直接转矩控制研究

Research of Direct Torque Control of Permanent Magnet Synchronous Motor Based on Fuzzy Control

针对常规永磁同步电机直接转矩控制存在转矩脉动较大的问题,提出了一种基于模糊控制的永磁同步电机直接转矩控制方法。该方法具有结构简单,易于实现的优点。仿真结果表明,该方法大大减小了转矩的脉动,提高了系统的控制性能。

For the problem of big torque ripple in conventional direct torque control of permanent magnetic synchronous motor, a PMSM DTC method based on fuzzy control is proposed. The method not only has the advantage of easy to implement, but also has the advantage of simplicity. Simulation result shows that the new control strategy decreases the torque ripple drastically and enhances the control performance.
