【摘要】：永磁磁通切換(flux switching permanent magnet,FSPM)電機(jī)具有功率密度高、轉(zhuǎn)子結(jié)構(gòu)簡單堅(jiān)固等優(yōu)勢,適合運(yùn)行在無刷交流場合。經(jīng)典的矢量控制和直接轉(zhuǎn)矩控制(direct torque control,DTC)可以應(yīng)用到FSPM電機(jī)系統(tǒng)中。DTC具有優(yōu)秀的轉(zhuǎn)矩動態(tài)性能,然而,轉(zhuǎn)速的動態(tài)性能受到轉(zhuǎn)速環(huán)PI參數(shù)的影響。因此,研究了一種轉(zhuǎn)矩沖量平衡控制來優(yōu)化轉(zhuǎn)速的動態(tài)性能�；谵D(zhuǎn)矩沖量平衡控制的思想,在動態(tài)過程中,該算法可以使得轉(zhuǎn)速只經(jīng)過一次調(diào)節(jié)(一次減速、一次升速)過程即可收斂,達(dá)到了最優(yōu)的轉(zhuǎn)速動態(tài)性能。仿真和實(shí)驗(yàn)結(jié)果驗(yàn)證了算法的正確性和有效性。
[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.
