energiyani tejash imkonini beradi.
Bunday energiya tejamkorligi, ayniqsa, o'zgaruvchan
momentli markazdan qochma kuch va nasos qo’shimchalarida yaqqol namoyon bo'ladi, bu
yerda yukning momenti va quvvati mos ravishda tezlikning kvadrati va kubiga qarab
o'zgaradi. Ushbu o'zgarish tezlikni nisbatan kichik kamaytirish
uchun katta tezlikda
ishlashga nisbatan katta quvvatni kamaytiradi. Misol uchun, 63%
tezlikda dvigatel yuki
to'liq tezlikdagi quvvatning atigi 25% ni iste'mol qiladi [10].
Vektor nazoratini qo'llashning muhim jihatlari:
tezlik yoki joylashuvni o'lchash yoki qandaydir baholash kerak;
moment va oqimni mos yozuvlarni o'zgartirish
orqali tez, 5-10 millisekunddan
kamroq vaqt ichida o'zgartirish mumkin;
agar PI boshqaruvi
ishlatilsa, qadam javobi biroz oshib ketadi;
tranzistorlarning o'tish chastotasi odatda doimiy va modulyator tomonidan
o'rnatiladi;
momentning aniqligi boshqaruvda ishlatiladigan vosita parametrlarining to'g'riligiga
bog'liq;
rotor haroratining o'zgarishi sababli katta xatolarga tez-tez duch keladi;
protsessorning monand ishlashi talab qilinadi;
boshqaruv algoritmi har bir siklida hisoblanadi.
