【摘要】：永磁磁通切换(flux switching permanent magnet,FSPM)电机具有功率密度高、转子结构简单坚固等优势,适合运行在无刷交流场合。经典的矢量控制和直接转矩控制(direct torque control,DTC)可以应用到FSPM电机系统中。DTC具有优秀的转矩动态性能,然而,转速的动态性能受到转速环PI参数的影响。因此,研究了一种转矩冲量平衡控制来优化转速的动态性能。基于转矩冲量平衡控制的思想,在动态过程中,该算法可以使得转速只经过一次调节(一次减速、一次升速)过程即可收敛,达到了最优的转速动态性能。仿真和实验结果验证了算法的正确性和有效性。
[Abstract]:Permanent magnet flux switching (flux switching permanent magnetn FSPM) motor has the advantages of high power density, simple and strong rotor structure, and is suitable for running in brushless AC field. Classical vector control and direct torque control (DTC) can be applied to FSPM motor system. DTC has excellent torque dynamic performance. However, the dynamic performance of rotational speed is affected by Pi parameters of speed loop. Therefore, a torque and impulse balance control is studied to optimize the dynamic performance of rotational speed. Based on the idea of torque and impulse balance control, in the dynamic process, the algorithm can make the speed of speed converge after only one adjustment (one deceleration, one increase), and achieve the optimal dynamic performance of speed. Simulation and experimental results show that the algorithm is correct and effective.
