چکیده | ||
در موتور سنکرون آهنربای دائم بدون یاتاقان، سیمپیچهای گشتاور و تعلیق مغناطیسی بهطور مشترک در شیارهای استاتور قرار دارند. زمانیکه رتور در مرکز استاتور نباشد بین دو سیمپیچ تزویج ایجاد میشود. در اغلب تحقیقاتی که پیرامون کنترلکننده این موتور گزارششده از تزویج بین سیمپیچها صرفنظر شده است. در این مقاله اثر تزویج بین این دو سیمپیچ بر عملکرد سامانه کنترل تعلیق مغناطیسی بررسیشده است. نتایج شبیهسازی نشان میدهد تزویج بین دو سیمپیچ قابلچشمپوشی نیست و اختلالهایی نظیر تغییر ناگهانی سیگنالهای مرجع مؤلفههای جابجایی شعاعی رتور و نیروهای شعاعی خارجی وارد بر محور موتور میتوانند نقطه تعادل رتور را جابجا نمایند. همچنین در این مقاله کنترلکننده مناسبی جهت دستیابی به عملکرد مطلوب موتور در برابر تغییر ناگهانی سیگنالهای مرجع مؤلفههای جابجایی شعاعی رتور با لحاظ تزویج سیمپیچها طراحیشده است. نتایج شبیهسازی ضرورت مدلسازی اثر تزویج و صحت روش پیشنهادی را تأیید میکند. | ||

Study on Impression of Coupling Between Torque and Maglev Windings on the Performance of BPMSM Suspension Control System | ||
چکیده [English] | ||
Inbearingless permanent magnet synchronous motor, both torque winding and magnetic levitation winding are placed in common stator slots. When the rotor is not in the center of the stator, coupling is established between two windings. In most of the researches to be realized about control of this motor, coupling between two windings is neglected. In this paper, the impression of coupling between two windings on performance of suspension control system is studied. Simulation results show that coupling between two windings is not negligible and disturbances such as sudden changing of reference signals of radial displacement components and radial forces on shaft can displace the equilibrium point of rotor. Furthermore, in this paper with consideration of coupling between two windings, a proper controller has been designed in order to attain the desired performance of the motor against the sudden changing of reference signals of radial displacement components. Simulation results confirm the necessity of coupling effect modeling and correctness of the proposed method. | ||
