Njengenxalenye ephambili yezinye izixhobo ezizenzekelayo, ukuthembeka kunye nokuzinza kwenkqubo yokulawula ukunyakaza kuchaphazela ngokuthe ngqo ukusebenza kwezixhobo, kwaye enye yezinto eziphambili ezichaphazela ukuthembeka kwayo nokuzinza kuyingxaki yokuchasana nokuphazamiseka.Ngoko ke, indlela yokusombulula ngempumelelo ingxaki yokuphazamiseka yingxaki engenakunakwa ekuyilweni kwenkqubo yokulawula intshukumo.
1. Ukuphazamiseka okwenzekayo
Kwisicelo, ezi zinto zilandelayo zophazamiso zidla ngokudibana nazo:
1. Xa inkqubo yokulawula ingakhuphi umyalelo, i-motor ijikeleza ngokungaqhelekanga.
2. Xa i-servo motor iyeka ukuhamba kwaye isilawuli esishukumayo sifunda indawo yemoto, ixabiso elizondliwa kwakhona yi-encoder photoelectric encoder ekupheleni kwemoto ixhuma ngokungaqhelekanga.
3. Xa i-servo motor isebenza, ixabiso le-encoder efundwayo alihambelani nexabiso lomyalelo okhutshiweyo, kwaye ixabiso lephutha liyi-random kwaye lingaqhelekanga.
4. Xa i-servo motor isebenza, umehluko phakathi kwexabiso le-encoder efundwayo kunye nexabiso lomyalelo okhutshiweyo lixabiso elizinzile okanye utshintsho ngamaxesha.
5. Isixhobo esabelana ngombane ofanayo kunye ne-AC servo system (efana nesiboniso, njl.njl.) ayisebenzi kakuhle.
2. Uhlalutyo lomthombo wokuphazamiseka
Kukho iindidi ezimbini eziphambili zamajelo aphazamisana nokungena kwinkqubo yokulawula intshukumo:
I-1, ukuphazamiseka kwesiteshi sokuhambisa umqondiso, ukuphazamiseka kungena ngejelo lokufaka umqondiso kunye nesiteshi esiphumayo esiqhagamshelwe kwinkqubo;
I-2, ukuphazamiseka kwenkqubo yokubonelela ngombane.
Ijelo lokuhambisa umqondiso yindlela yenkqubo yokulawula okanye umqhubi ukufumana izibonakaliso zengxelo kunye nokuthumela iimpawu zokulawula, kuba i-wave wave iya kulibaziseka kwaye iphazamise kumgca wokuhambisa, ukutshatyalaliswa kunye nokuphazamiseka kwesiteshi, kwinkqubo yokuhambisa, ixesha elide. ukuphazamisa yeyona nto iphambili.
Kukho ukuchasana kwangaphakathi kuwo nawuphi na unikezelo lwamandla kunye nemigca yokuhambisa.Zizo ezi zichasi zangaphakathi ezibangela ukuphazamiseka kwengxolo yonikezelo lwamandla.Ukuba akukho ukuchasana kwangaphakathi, kungakhathaliseki ukuba luhlobo luni lwengxolo oluya kuthatyathwa ngumbane omfutshane-wesiphaluka, akukho mbane wokuphazamiseka uya kusekwa kumgca., Umqhubi wenkqubo ye-AC servo ngokwayo ungumthombo onamandla wokuphazamiseka, unokuphazamisana nezinye izixhobo ngokusebenzisa umbane.
Inkqubo yokulawula ukunyakaza
Ezintathu, amanyathelo achasene nokuphazamiseka
1. Uyilo oluchasene nokuphazamiseka kwenkqubo yokubonelela ngombane
(1) Ukuphumeza unikezelo lwamandla kumaqela, umzekelo, ukwahlula amandla okuqhuba i-motor kumandla okulawula ukukhusela ukuphazamiseka phakathi kwezixhobo.
(2) Ukusetyenziswa kwezihluzi zengxolo nako kunokucinezela ngempumelelo ukuphazamiseka kwe-AC servo drives kwezinye izixhobo.Lo mlinganiso unokucinezela ngokufanelekileyo oku kuphazamiseka okukhankanywe ngasentla.
(3) I-transformer yodwa iyamkelwa.Ukuqwalasela ukuba ingxolo ye-high-frequency idlula kwi-transformer ngokukodwa kungekhona ngokudibanisa kwe-conductance yokubambisana kwee-coil eziphambili kunye ne-sekondari, kodwa ngokudibanisa i-capacitances ye-parasitic yokuqala kunye neyesibini, amacala aphambili kunye nesibini kwi-transformer yodwa ahlukaniswe ngamacandelo akhuselayo. ukunciphisa amandla abo okusasazwa ukuphucula amandla okumelana nokuphazamiseka kwemowudi eqhelekileyo.
2. Uyilo oluchasene nokuphazamiseka kwendlela yokuhambisa umqondiso
(1) Imilinganiselo yokudibanisa i-Photoelectric yokudibanisa
Kwinkqubo yokuhanjiswa komgama omde, ukusetyenziswa kweefotocouplers kunokunqumla uxhulumaniso phakathi kwenkqubo yokulawula kunye nejelo lokungena, ishaneli yokuphuma, kunye negalelo kunye nemveliso ye-servo drive.Ukuba i-photoelectric isolation ayisetyenziswanga kwisekethe, isignali yokuphazamiseka kwe-spike yangaphandle iya kungena kwisistim okanye ingene ngokuthe ngqo kwisixhobo se-servo drive, ibangele into yokuqala yokuphazamiseka.
Inzuzo ephambili yokudibanisa ifotoelectric kukuba inokucinezela ngokufanelekileyo izikhonkwane kunye nokuphazamiseka kwengxolo eyahlukeneyo,
Ngoko ke, umlinganiselo wesignali-kwingxolo kwinkqubo yokuhambisa umqondiso uphuculwe kakhulu.Esona sizathu siphambili: Nangona ingxolo yokuphazamiseka ine-amplitude enkulu yombane, amandla ayo mancinci kwaye anokwenza kuphela umsinga obuthathaka.I-diode ekhupha ukukhanya kwenxalenye yegalelo le-photocoupler isebenza phantsi kwemeko yangoku, kwaye i-conduction current jikelele yi-10-15mA, ngoko Nangona kukho ukuphazamiseka okuphezulu kwe-amplitude, icinezelwe ngenxa yokuba ayikwazi ukubonelela ngoku okwaneleyo ngoku.
(2) Iingcingo ezijijekileyo ezikhuselweyo kunye nokuhanjiswa kocingo olude
Umqondiso uya kuchaphazeleka kwizinto eziphazamisayo ezifana nentsimi yombane, intsimi yamagnetic kunye ne-impedance yomhlaba ngexesha lokuhanjiswa.Ukusetyenziswa kocingo olusezantsi lokukhusela kunokunciphisa ukuphazamiseka kwintsimi yombane.
Xa kuthelekiswa nentambo ye-coaxial, intambo ejijekileyo inebhendi yamaza asezantsi, kodwa ine-impedance ephezulu yamaza kunye nokuchasana okuqinileyo kwingxolo yemowudi eqhelekileyo, enokuthi irhoxise uphazamiseko lwe-electromagnetic induction.
Ukongezelela, kwinkqubo yokuhanjiswa kwexesha elide, ukuhanjiswa kweempawu ezihlukeneyo ngokuqhelekileyo kusetyenziselwa ukuphucula ukusebenza kokuphazamiseka.Ukusetyenziswa kocingo olujijekileyo olukhuselweyo kuthungelwano locingo olude lunokucinezela ngokufanelekileyo into yesibini, eyesithathu, neyesine yokuphazamiseka.
(3) Umhlaba
Ukugaywa komhlaba kunokuphelisa amandla ombane wengxolo owenziweyo xa umsinga uqukuqela ngocingo lomhlaba.Ukongeza ekudibaniseni inkqubo ye-servo emhlabeni, ucingo lokukhusela umqondiso kufuneka lubekwe phantsi ukuze kuthintelwe ukungeniswa kwe-electrostatic kunye nokuphazamiseka kwe-electromagnetic.Ukuba ayisekelwanga ngokufanelekileyo, into yesibini yokuphazamiseka ingenzeka.
