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.“,”Flux switching permanent magnet (FSPM) machine having high torque density and robust rotor structure is suitable for brushless AC (BLAC) operation,and the classical vector control (VC) and direct torque control (DTC)method can be employed in the FSPM machine systems.The direct torque control system has excellent dynamic performance of electromagnetic torque,however,the dynamic performance of the speed is affected by the PI parameters of the speed closed loop.Hence,this paper investigated a control method to achieve the optimal dynamic performance of the speed.Based on the integration balance of sine value of the torque angle,this method can make the speed and the electromagnetic torque converge simultaneously after the speed adjusting only once.Thus,the best possible dynamic response for the speed can be achieved.The experimental results verify the correctness and effectiveness of the proposed algorithm.
