Nrog kev tawm tsam ntawm lub sijhawm ntawm kev txawj ntse thiab Is Taws Nem ntawm yam, kev tswj kom tsim nyog ntawm lub tsheb kauj ruam dhau los ua kom muaj tseeb. Txhawm rau txhim kho qhov tseeb thiab kev ntseeg tau ntawm lub cev muaj zog stepper, cov kev tswj hwm ntawm theem ntaiv tau piav qhia los ntawm plaub qhov lus qhia:
1. PID tswj: Raws li muab cov nqi R (T)
2, kev hloov pauv tau: Nrog rau cov nyom ntawm cov khoom tswj, thaum cov kev hloov pauv tsis tau paub, kom tau txais kev hloov pauv ntawm cov linear lossis kwv yees li linear qauv ntawm lub cev muaj zog stepper. Nws cov ntsiab lus tseem ceeb tau yooj yim los siv thiab kev hloov pauv nrawm nrawm, tab sis cov teeb meem kev tswj hwm tau siv tau ntawm cov qauv kev tsis sib haum xeeb
3, Vector tswj yog qhov theoretical hauv paus ntawm kev tswj hwm niaj hnub kev tswj hwm, uas tuaj yeem txhim kho cov torque tswj kev ua tau zoo ntawm lub cev muaj zog. Nws faib cov stator tam sim no mus rau hauv kev zam kev zam thiab thaj chaw tiv thaiv kom tswj tau los ntawm kev sib nqus kab ke, yog li kom tau txais cov yam ntxwv zoo. Yog li ntawd, Vector tswj yuav tsum tau tswj hwm ob qho tib si amplitude thiab theem ntawm stator tam sim no.
4, intelligent control: it breaks through the traditional control method that must be based on the framework of mathematical models, does not rely on or not completely rely on the mathematical model of the control object, only according to the actual effect of control, in the control has the ability to consider the uncertainty and accuracy of the system, with strong robustness and adaptability. Tam sim no, fuzzy logic tswj thiab neural network tswj tau ntau dua nyob rau hauv daim ntawv thov.
(1) Kev tswj hwm fuzzy: kev tswj hwm fuzzy yog ib txoj kev kom paub cov kev tswj hwm cov txheej txheem raws li tus qauv fuzzy ntawm kev tswj hwm khoom thiab kwv yees kev xav ntawm lub fuzzy maub los. Lub kaw lus tau nce qib kaum sab xis tswj, tus qauv tsim tsis tas yuav ua qauv lej, lub sijhawm nrawm yog luv.
(2) Network network tswj: Siv cov lej ntawm neurons raws li ib qho kev paub meej meej, nws tuaj yeem kawm thiab hloov kho tsis paub meej thiab muaj zog rau kev ua txhaum.
TT cov cuab yeej siv hluav taws xob, cov cuab yeej siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom ua si hluav taws xob, cov khoom ua si hluav taws xob, khoom siv hluav taws xob thiab lwm yam khoom siv hluav taws xob.
