1. Umgaqo osebenzayo womqhubi we-servo:
Okwangoku, abaqhubi be-servo besiqhelo bonke basebenzisa iprosesa yesignali yedijithali (DSP) njengesiseko solawulo, esinokuqonda i-algorithm yokulawula enzima ngakumbi, kwaye iqonde idijithali, inethiwekhi kunye nokuqonda.Izixhobo zamandla ngokubanzi zisebenzisa imodyuli yamandla akrelekrele (IPM) njengoyilo oluphambili lwesekethe yokuqhuba, i-IPM yangaphakathi yesekethe yedrive edibeneyo, kwaye ine-overvoltage, i-overcurrent, overheating, undervoltage kunye nezinye isekethe yokukhusela impazamo, kwisekethe ephambili yongeze isekethe yokuqala ethambileyo. , ukwenzela ukunciphisa impembelelo yenkqubo yokuqala kumqhubi.Iyunithi yokuqhuba amandla kuqala ilungisa igalelo lesigaba sesithathu okanye umbane oyintloko ngokusebenzisa inqanaba lesithathu lebhulorho egcweleyo yokulungisa isekethe ukuze ifumane umsinga othe ngqo ohambelanayo.Isigaba sesithathu semagnethi esisigxina ye-synchronous AC servo motor iqhutywa yi-inverter ye-sinusoidal PWM yesigaba esithathu.Yonke inkqubo yeyunithi yokuqhuba amandla inokuchazwa ngokulula njengenkqubo ye-AC-DC-AC.Isekethe ephambili ye-topological ye-AC-DC sisigaba sesithathu esigcweleyo - ibhulorho engalawulwayo yokubuyisela isekethe.
Ngokusetyenziswa komgangatho omkhulu wenkqubo ye-servo, ukusetyenziswa kwe-servo drive, ukulungiswa kwe-servo drive, ukugcinwa kwe-servo drive zibaluleke ngakumbi izihloko zobugcisa kwi-servo drive yanamhlanje, ngakumbi nangakumbi ababoneleli benkonzo yolawulo lweshishini kwi-servo drive itekhnoloji yophando olunzulu. .
Umqhubi we-Servo yinxalenye ebalulekileyo yolawulo lwentshukumo yanamhlanje, esetyenziswa kakhulu kwiirobhothi zoshishino kunye namaziko omatshini e-CNC kunye nezinye izixhobo ezizenzekelayo.Ngokukodwa, umqhubi we-servo osetyenziselwa ukulawula i-AC yemagnethi esisigxina ye-synchronous motor ibe yindawo yophando ekhaya nakwamanye amazwe.Okwangoku, isantya, isikhundla se-3 i-algorithm yokulawula i-loop evaliweyo esekelwe kulawulo lwe-vector isetyenziswa ngokubanzi kwi-AC servo driver design.Ingaba i-speed evaliweyo i-loop design kule algorithm inengqiqo okanye ayidlali indima ephambili kuyo yonke inkqubo yokulawula i-servo, ngakumbi ekusebenzeni kokulawula isantya.
2. Umqhubi we-Servo:
Njengenxalenye ebalulekileyo yolawulo lwentshukumo yanamhlanje, isetyenziswa kakhulu kwiirobhothi zoshishino kunye namaziko omatshini eCNC kunye nezinye izixhobo ezizenzekelayo.Ngokukodwa, umqhubi we-servo osetyenziselwa ukulawula i-AC yemagnethi esisigxina ye-synchronous motor ibe yindawo yophando ekhaya nakwamanye amazwe.Okwangoku, isantya, isikhundla se-3 i-algorithm yokulawula i-loop evaliweyo esekelwe kulawulo lwe-vector isetyenziswa ngokubanzi kwi-AC servo driver design.Ingaba i-speed evaliweyo i-loop design kule algorithm inengqiqo okanye ayidlali indima ephambili kuyo yonke inkqubo yokulawula i-servo, ngakumbi ekusebenzeni kokulawula isantya.
Kwisantya esivaliweyo somqhubi we-servo, ukuchaneka kwexesha lokwenyani lokulinganisa isantya se-motor rotor kubaluleke kakhulu ekuphuculeni iimpawu eziguquguqukayo kunye ne-static zolawulo lwesantya se-loop yesantya.Ukuze ufumane ibhalansi phakathi kokuchaneka komlinganiselo kunye neendleko zenkqubo, i-encoder ye-photoelectric encoder isetyenziswa ngokubanzi njengenzwa yokulinganisa isantya, kwaye indlela yokulinganisa isantya ehambelanayo yi-M / T.Nangona i-tachometer ye-M / T inokuchaneka kokuchaneka kokulinganisa kunye noluhlu olubanzi lokulinganisa, ineziphene zayo zendalo, ezibandakanya: 1) ubuncinane i-disk pulse enye epheleleyo kufuneka ifumaneke kwixesha lokulinganisa, elikhawulela ubuncinci besantya esinomlinganiselo;I-2) Kunzima ukutshintshwa kwexesha leenkqubo ezimbini zokulawula ezisetyenziselwa ukulinganisa isantya ukugcina ulungelelwaniso oluqinileyo, kwaye ukuchaneka komlinganiselo wesantya akunakuqinisekiswa kwizihlandlo zokulinganisa kunye neenguqu ezinkulu zesantya.Ke ngoko, kunzima ukuphucula ukusebenza kwesantya sokulandela umqhubi we-servo kunye nokulawula ngokusebenzisa indlela yoyilo lwelophu yesantya yemveli.
Inkcukacha ezithe vetshe:
I. Indawo yesicelo:
I-Servo drive isetyenziswa ngokubanzi kumatshini wokubumba inaliti, oomatshini belaphu, oomatshini bokupakisha, izixhobo zoomatshini be-CNC njalo njalo.
Ii.Umahluko ofanelekileyo:
1. Umlawuli we-servo unokuguqula ngokulula imodyuli yokusebenza kunye nemodyuli ye-fieldbus ngokusebenzisa ujongano oluzenzekelayo.Ngexesha elifanayo, iimodyuli ezahlukeneyo ze-fieldbus zisetyenziselwa ukufikelela kwiindlela ezahlukeneyo zokulawula (RS232, RS485, fiber optical, InterBus, ProfiBus), kunye nemowudi yokulawula i-converter frequency converter ngokulinganayo eyodwa.
2. Umlawuli we-servo uqhagamshelwe ngokuthe ngqo kwi-transformer ye-rotary okanye i-encoder ukwenza i-loop evaliweyo yesantya kunye nolawulo lokuhamba.Kodwa isiguquli sefrikhwensi yendalo iphela sinokwenza kuphela inkqubo yokulawula i-loop evulekileyo.
3. Isalathiso ngasinye solawulo (njengokuchaneka kobume obuzinzileyo kunye nokusebenza okuguquguqukayo, njl.njl.) Isilawuli se-servo singcono kunomguquli oqhelekileyo.
