Pane maonero akawanda pamusoro panotaurwa ari kuongorora servo injini jitter mhosva:
Chekutanga,
1. Kana PID pfuma kugadziridzwa iri guru, zviri nyore kuti chikonzero chinonzi motor jitter, kunyanya pashure achiwedzera D, riri kunyanya chakakomba, saka edza kuwedzera P uye kuderedza Ini, zvinganaka Usawedzera D.
2. Kana encoder wiring kwakaipa, jitter ndichamuramba kuitika.
3. Kana mutoro inertia iri guru, akatsiva makuru injini uye mutyairi.
4. kuvhiringidza analoginen chiyamuro pachiteshi kunokonzera jitter. Wedzerai simba rinonzi magnetic mhete mazano rwonzi injini uye simba nerubatsiro chiyamuro mutsara servo mutyairi kuchengeta chiratidzo mutsetse kubva simba mutsetse.
5. Panewo muhombe encoder inowanikwa injini, riri nyore kuti chikonzero vibration kana varombo grounding.
Chepiri.
1. Servo wiring:
A. cheki kana mureza simba wire, encoder waya, kudzora wire uye waya wakaremara;
B. cheki kana pane kukanganiswa pedo kudzorwa mutsetse uye kana zvinofambirana kana zvakare pedyo pedyo yakakwirira ano simba waya;
C. cheki kana zvinogona of grounding kuchinja chinouraya, uye nechokwadi zviri grounding zvakanaka.
2. Servo parameters:
A. ari servo pfuma marongero chakanyanya guru. Zvinokurudzirwa kururamisa servo parameters manually kana zvaitika;
B. asimbise mamiriro nguva kuramba kuti akurumidze inofambiswa Sefa, kwokutanga mutengo uri 0, uye edza kuwedzera pakuvira mutengo;
C. electronic giya reshiyo iri guru, Zvinokurudzirwa kudzorera kuti fekitari pakuvira;
D. resonance kuti servo maitiro uye zvokuimba gadziriro, edza kugadzirisa kakawanda uye amplitude kuti notch firita.
3. Mechanical maitiro:
A. panaakabatanidzwa pamwechete unobva injini mugodhi uye zvokushandisa gadziriro iri vakatsauka, uye nokuwedzera screws vasina akasungirirwa;
B. varombo kuroorana zviri chisimudziso kana giya kuchaitawo kuti mutoro torque kuchinja, uye edza kushandisa pasina mutoro. Kana oparesheni romuzvarirwo pasina mutoro, tarisa kana vagari chikamu zvokuimba kwava kanganisika;
c. Zvinosimbisa kana mutoro inertia, torque uye speed zvakare guru. Edza kushanda pasina mutoro. Kana pasina-mutoro oparesheni romuzvarirwo, kuderedza mutoro kana kutsiva mutyairi uye injini pamwe hombe tichikwanisa.
Chetatu.
Servo gwenya jitter kunokonzerwa zvokuimba yakarongeka, kumhanya loop, muripo revatungamiriri servo ezvinhu, servo gudzazwi, mutoro inertia, zvemagetsi chikamu nezvimwe zvikanganiso.
1. Vibration anokonzerwa zvokuimba marongerwo inogona kukamurwa ezvinhu matatu:
1) No mutoro jitter:
a. Injini hwaro haasi yakasimba, asi Rigidity hakuna kukwana kana Kuda kutamba haisi zvakasimba.
b. The feni chipande wakaremara, iyo anoparadza zvokuimba pakuenzanisa rotor.
c. Nomubato ndeyokubvisa kana wakatsemuka. It zvinogona kugadziriswa fastening screws, achitsiva kurudza mashizha, achitsiva miseve, etc.
2) Kana vibration anokonzerwa mhosva pakati nokupfuuridzirwa mudziyo pashure mutoro wacho akawedzera, zvinganzi kutongwa kuti zvikamu zviri chakaremara:
a. Kudzikama vachishandisa kutenderera bhandi chisimudziso kana coupling.
b. Muzinda rwonzi panaakabatanidzwa pamwechete dzisingapindirani, saka kuti injini uye zvokuimba akabatana ari nemotokari havasi coincident.
c. Kudzikama ngarurege bhandi muhudyu. Anogona kugadziriswa nokuchinja kufambisa mudziyo kuti akadzikama.
2. Jitter anokonzerwa dambudziko kumhanya loop: The parameters zvakadai chinokosha dzokusatendeseka, Proportional yakaipa uye kumhanyisa inofambiswa pfuma velocity loop vari kukodzera. The yakakura kuhuwana, mukuru nokukurumidza, kunokonzera inertia simba, duku nokutsauka, uye tichikurumidza jitter. Kuronga chiduku pfuma inogona kuramba nokukurumidza norudaviro uye hazvisi nyore kuti vaunze jitter.
3. Jitter kunokonzerwa mhosva kuti muripo bhodhi uye servo gudzazwi pamusoro servo hurongwa: Munguva injini sangano, nokukundwa simba kukundikana uye rurege chikonzero jitter kukuru, riri chokuita BRK inouraya kuti servo gudzazwi uye kukodzera pakuvira parameters. The kumhanyisa uye deceleration nguva dzose kunogona wakawedzera, uye PLC rinogona kushandiswa kutanga kana kumisa injini zvishoma nezvishoma kuti harimuzunguzi.
4. Jitter anokonzerwa mutoro inertia: The zvinetso mutungamiriri njanji uye sikuruu achitungamirira zvibereko mutoro inertia. Nguva inertia kuti mutungamiriri njanji uye vatungamirire sikuruwa ine simba guru pamusoro Rigidity kuti servo injini tikachirega hurongwa. Under yakatarwa pfuma, chikuru Nguva inertia, kunokonzera Rigidity, kwakondiko kuti chikonzero injini jitter; duku panguva inertia, ikava duku Rigidity, kashoma injini jitter. Inogona kuderedza nguva inertia kuti mutoro nokutsiva mutungamiriri njanji uye sikuruwa netsvimbo pamwe dhayamita duku, kuitira kuti injini harimuzunguzi.
5. Jitter anokonzerwa magetsi chikamu:
a. The kuvhuna haina kuzarurwa, uye inofambiswa voltage iri kugadzikana. Check kana kuvhuna dzikaita pamusoro. Wedzera zero servo mashandiro encoder vektori kuzvidzora, uye goho imwe torque munzira torque rutapudzo yokugadzirisa jitter. Kana inofambiswa voltage riri kanganisika, tanga kuongorora kana vibration nguva iri chokuita nokukurumidza. Kana ukama, cheki kana kubatana pakati huru mugodhi uye huru mugodhi injini kutadza, uye kana huru mugodhi uye kurova kwemwoyo jenareta yakaiswa panoperera ari AC chikuru mugodhi injini wakaremara. Kana kwete, tarisa kana rakadhindwa redunhu bhodhi iri hunonyengera. Check redunhu bhodhi kana kururamisa nayo.
b. Kana injini pakarepo vibrates panguva ichishanda, zvakawanda izvo zvinokonzerwa danho kurasikirwa, zvakakosha kuongorora kana fiyuzi uchanyangadika iri fused, kana chinja neshamwari zvakanaka, uye kana chimwe nechimwe chehupenyu simba afoot ane simba.
