Umgaqo wokusebenza we-servo motor

A imoto ye-servoyimoto enokulawula ngokuchanekileyo indawo, isantya, kunye nokukhawulezisa kwaye isetyenziswa rhoqo kwizicelo ezifuna ulawulo lokuhamba oluchanekileyo. Ingaqondwa njengemoto ethobela umyalelo wesignali yokulawula: ngaphambi kokuba uphawu lokulawula lukhutshwe, i-rotor ayimi; Xa uphawu lokulawula luthunyelwa, i-rotor ijikeleza ngoko nangoko; Xa uphawu lokulawula lulahlekile, i-rotor inokuma ngoko nangoko. Umgaqo wayo wokusebenza ubandakanya inkqubo yolawulo, i-encoder kunye ne-feedback loop. Oku kulandelayo yinkcazo eneenkcukacha yendlela esebenza ngayo ii-servo motors:

Inkqubo yoLawulo: Inkqubo yokulawula yemoto ye-servo idla ngokuba nomlawuli, umqhubi kunye nemoto. Umlawuli ufumana imiqondiso yokulawula evela ngaphandle, njengemiyalelo yendawo okanye imiyalelo yesantya, aze emva koko aguqule le miqondiso ibe yimiqondiso yangoku okanye ye-voltage aze ayithumele kumqhubi. Umqhubi ulawula ukujikeleza kwemoto ngokwesignali yokulawula ukuze afezekise indawo efunekayo okanye ulawulo lwesantya.

I-Encoder: Iimoto zeServo zihlala zixhotyiswe nge-encoder yokulinganisa indawo yokwenyani ye-rotor yemoto. I-encoder inika ulwazi lwendawo ye-rotor kwinkqubo yolawulo ukuze inkqubo yolawulo ikwazi ukujonga indawo yemoto ngexesha langempela kwaye iyilungise.

I-Feedback loop: Inkqubo yolawulo lwee-servo motors idla ngokusebenzisa ulawulo oluvaliweyo, olulungisa imveliso yemoto ngokulinganisa rhoqo indawo yokwenyani nokuyithelekisa nendawo efunekayo. Le feedback loop iqinisekisa ukuba indawo yemoto, isantya, kunye nokukhawulezisa kwayo ziyahambelana nomqondiso wolawulo, nto leyo evumela ulawulo oluchanekileyo lokushukuma.

I-algorithm yokulawula: Inkqubo yolawulo lwe-servo motor idla ngokusebenzisa i-algorithm yokulawula ye-PID (proportional-integral-derivative), ehlala ilungisa imveliso yemoto ukuze yenze indawo yokwenyani ibe kufutshane kangangoko kwindawo oyifunayo. I-algorithm yokulawula ye-PID inokulungisa imveliso yemoto ngokusekelwe kumahluko phakathi kwendawo yokwenyani nendawo oyifunayo ukuze kufezekiswe ulawulo oluchanekileyo lwendawo.

Kwimisebenzi yokwenyani, xa inkqubo yolawulo ifumana imiyalelo yendawo okanye yesantya, umqhubi uya kulawula ukujikeleza kwemoto ngokusekelwe kule miyalelo. Kwangaxeshanye, i-encoder isoloko ilinganisa indawo yokwenyani ye-motor rotor kwaye inika olu lwazi kwakhona kwinkqubo yolawulo. Inkqubo yolawulo iya kulungisa imveliso yemoto nge-PID control algorithm ngokusekelwe kulwazi lokwenyani lwendawo oluxhaswa yi-encoder, ukuze indawo yokwenyani isondele kangangoko kwindawo oyifunayo.

Umgaqo wokusebenza wemoto ye-servo unokuqondwa njengenkqubo yokulawula evaliweyo ehlala ilinganisa indawo yokwenyani kwaye iyithelekise nendawo efunekayo, kwaye ilungise imveliso yemoto ngokwemahluko ukuze ifikelele kwindawo echanekileyo, isantya kunye nolawulo lokukhawulezisa. Oku kwenza iimoto ze-servo zisetyenziswe kakhulu kwizicelo ezifuna ulawulo lokuhamba oluchanekileyo, njengezixhobo zoomatshini be-CNC, iirobhothi, izixhobo zokwenza izinto ngokuzenzekelayo kunye nezinye iindawo.
