Sezvo chikamu chepakati cheimwe midziyo yeautomation, kuvimbika uye kugadzikana kweiyo motion control system inokanganisa zvakananga kushanda kwemidziyo, uye chimwe chezvinhu zvikuru zvinokanganisa kuvimbika kwayo uye kugadzikana idambudziko rekurwisa-kupindira.Nokudaro, nzira yekugadzirisa zvinobudirira dambudziko rekupindira idambudziko risingagoni kuregererwa mukugadzirwa kwehurongwa hwekufambisa.
1. Kupindira kwechiitiko
Muchikumbiro, zvinotevera zvinonyanya kukanganisa zviitiko zvinowanzosangana nazvo:
1. Kana iyo control system isingabudisi murairo, mota inotenderera zvisingaite.
2. Kana iyo servo mota inomira kufamba uye mutungamiriri wekufamba achiverenga chinzvimbo chemota, kukosha kunodzoserwa neiyo photoelectric encoder pamagumo emota inosvetuka zvisina tsarukano.
3. Kana iyo servo mota iri kushanda, kukosha kweiyo encoder kuverenga hakuenderane nekukosha kwemurairo wakapihwa, uye kukosha kwekukanganisa kwakasarudzika uye kusingaite.
4. Kana iyo servo mota ichimhanya, mutsauko pakati pekuverenga encoder kukosha uye yakapihwa yekuraira kukosha kukosha kwakagadzikana kana kushanduka nguva nenguva.
5. Midziyo inogovera simba rimwechete ne AC servo system (yakadai sekuratidzira, nezvimwewo) haishande zvakanaka.
2. Kupindira kunobva kuongororwa
Kune marudzi maviri makuru ematanho anovhiringa kupinda mukati meiyo motion control system:
1, chiratidzo chekufambisa chiteshi kupindira, kupindira kunopinda kuburikidza neiyo chiratidzo chekuisa chiteshi uye inobuda chiteshi chakabatana nehurongwa;
2, kupindira kwemagetsi system.
Chiratidzo chekufambisa chiteshi ndiyo nzira yekuti control system kana mutyairi agamuchire masaini emhinduro uye kutumira masaini ekudzora, nekuti iyo pulse wave inononoka uye yakakanganiswa pamutsetse wekutapurirana, attenuation uye kupindira kwechiteshi, mukufambisa, kwenguva refu. kupindira ndicho chinhu chikuru.
Kune kupikisa kwemukati mune chero simba rekupa uye mitsara yekutumira.Ndiko kupikisa kwemukati uku kunokonzera kukanganiswa kweruzha rwemagetsi.Kana pasina kupikisa kwemukati, zvisinei kuti rudzii rweruzha ruchatorwa nemagetsi emagetsi mapfupi-circuit, hapana kupindira kwemagetsi kuchamiswa mumutsara., AC servo system mutyairi pachayo zvakare inzvimbo yakasimba yekuvhiringidza, inogona kupindira nemimwe michina kuburikidza nemagetsi.
Motion Control System
Tatu, anti-kupindira matanho
1. Anti-kupindira dhizaini yemagetsi ekupa system
(1) Shandisa magetsi mumapoka, semuenzaniso, patsanura simba rekutyaira remota kubva kune simba rekudzora kudzivirira kukanganisa pakati pemidziyo.
(2) Kushandiswa kwemafirita eruzha kunogonawo kudzvanya kukanganiswa kweAC servo drives kune mimwe michina.Ichi chiyero chinogona kunyatso kudzvanyirira kupindira kwataurwa pamusoro apa.
(3) Iyo yekuzviparadzanisa transformer inogamuchirwa.Tichifunga kuti ruzha rwepamusoro-soro runopfuura nemushanduri kunyanya kwete nekubatanidza inductance coupling yemakoiri ekutanga uye echipiri, asi nekubatanidza kwekutanga uye yechipiri parasitic capacitances, mativi ekutanga uye echipiri ega ega transformer anoparadzaniswa nekudzivirira zvidimbu. kuderedza yavo Distributed capacitance kuvandudza kugona kuramba common mode kupindira.
2. Anti-kupindira dhizaini yechiratidzo chekufambisa chiteshi
(1) Photoelectric coupling yekuzviparadzanisa matanho
Mukuita kwekutumira kure-kure, kushandiswa kwemafotocouplers kunogona kugura kubatana pakati peiyo control system uye yekupinza chiteshi, inobuda chiteshi, uye yekupinza uye yekubuda nzira yeservo drive.Kana iyo photoelectric isolation ikasashandiswa mudunhu, chiratidzo chekunze spike chinopindira chinopinda muhurongwa kana kupinda zvakananga servo drive mudziyo, zvichikonzera yekutanga kupindira chiitiko.
Mukana mukuru wekubatanidza photoelectric nderekuti unogona kunyatso kudzvanya spikes uye nekukanganisa kwakasiyana kweruzha,
Naizvozvo, iyo chiratidzo-kune-ruzha reshiyo mune iyo chiratidzo chekufambisa maitiro inovandudzwa zvakanyanya.Chikonzero chikuru ndechekuti: Kunyangwe ruzha rwekukanganisa rune yakakura voltage amplitude, simba rayo idiki uye rinogona kungoita isina simba ikozvino.Iyo light-emitting diode yechikamu chekuisa chefotocoupler inoshanda pasi pemamiriro ezvino, uye general conduction ikozvino ndeye 10-15mA, saka Kunyange kana paine kupindira kwepamusoro amplitude, inodzvinyirirwa nekuti haigone kupa yakakwana ikozvino.
(2) Twisted-pair shield wire uye refu-waya kutapurirana
Chiratidzo chichakanganiswa nekukanganisa zvinhu zvakadai semagetsi, magnetic field uye pasi impedance panguva yekufambisa.Kushandiswa kwewaya yekudzivirira pasi kunogona kuderedza kupindira kwemunda wemagetsi.
Kuenzaniswa necoaxial tambo, yakamonyoroka-pairi tambo ine yakaderera frequency bhendi, asi ine yakakwira wave impedance uye yakasimba kuramba kune yakajairika modhi ruzha, iyo inogona kudzima mumwe nemumwe kukanganiswa kwemagetsi induction.
Uye zvakare, mukufambiswa kwekureba-kure, kutapurirana kwechiratidzo chekusiyanisa kunowanzoshandiswa kuvandudza mashandiro ekurwisa-kupindira.Kushandiswa kwewaya yakamonyoroka-yakadzivirirwa yekufambisa-waya-yakareba inogona kudzvanya chechipiri, chechitatu, uye chechina chekukanganisa chiitiko.
(3) Pasi
Grounding inogona kubvisa voltage yeruzha inogadzirwa kana ikozvino ichiyerera nepasi waya.Pamusoro pekubatanidza iyo servo system pasi, iyo chiratidzo chekudzivirira waya inofanirawo kuiswa pasi kudzivirira electrostatic induction uye electromagnetic kukanganiswa.Kana iyo isina kunyatsodzika pasi, yechipiri kupindira chiitiko chinogona kuitika.
