1, Kumvetsetsa zakufa zone, hysteresis, kulondola kwa malo, kusanja kwa siginecha, ndikuyika magwiridwe antchito pakuwongolera servo
Chifukwa cha kugwedezeka kwa ma siginecha ndi zifukwa zina, chizindikiro cholowetsamo ndi chizindikiro cha mayankho a dongosolo lililonse lotsekeka lotsekeka silingakhale lofanana kwathunthu, lomwe limaphatikizapo vuto la control zone of dead and hysteresis. Dongosolo silingathe kusiyanitsa kusiyana pakati pa chizindikiro cholowetsa ndi chizindikiritso cha mayankho, chomwe ndi gawo lowongolera lakufa.
Chifukwa cha kusinthasintha kwa ma sign, kulondola kwamakina, ndi zifukwa zina, makina owongolera a servo nthawi zonse amasintha pang'onopang'ono kunja kwa gawo lakufa lolamulira. Pofuna kuteteza servo kuti isasinthe ku oscillations pang'ono, zotsatira za hysteresis ziyenera kuyambitsidwa.
The hysteresis control dead zone ndi yayikulu, yokhala ndi zone yakufa ya ± 0.4%. The hysteresis loop ikhoza kukhazikitsidwa ku ± 2%.

 

Kusiyanitsa pakati pa chizindikiro cholowetsamo ndi chizindikiro cha ndemanga sikuchititsa kuti galimoto isunthe mkati mwa hysteresis loop. Kusiyanitsa pakati pa chizindikiro cholowetsamo ndi chizindikiro choyankha kumalowa mumtundu wa hysteresis, ndipo injini imayamba kusweka ndikuyimitsa.
Kulondola kwa malodzimatengera kulondola kwathunthu kwa servo system, monga control zone dead, kulondola kwa makina, kulondola kwa potentiometer ya mayankho, ndikusintha kwa siginecha. Kusintha kwa siginecha yolowera kumatanthawuza kusinthasintha kocheperako kwa servo system ya siginecha yolowera, ndipo kuyika kwa chizindikiro cha digito servo ndikwabwinoko kuposa kwa analogi servo. Kubwereranso kumadalira hysteresis ndi kulondola kwa malo.

 

 

2, Chifukwa chiyani servo nthawi zonse imapanga phokoso
Servo nthawi zonse imapanga phokoso lakumbuyo ndi mtsogolo, chifukwa ma servos ena amachitaalibe hysteresis kusintha ntchito, ndipo gawo lowongolera lakufa limasinthidwa kukhala laling'ono. Malingana ngati chizindikiro cholowetsamo ndi chizindikiro cha mayankho nthawi zonse chimasinthasintha, ndipo kusiyana kwawo kumadutsa malo olamulira akufa, servo imatumiza chizindikiro kuti iyendetse galimotoyo.
Kuonjezera apo, popanda hysteresis kusintha ntchito, ngati makina olondola a servo gear set ndi osauka, malo enieni a dzino ndi aakulu, ndipo kusinthasintha kwa mayankho a potentiometer kumaposa kulamulira kwakufa zone, servo idzasintha mosalekeza ndikugwedeza mosalekeza.

 

3. Chifukwa chiyani ma servos ena amaphulika ndikuwotcha matabwa ozungulira mosavuta
Ma servos ena amagwiritsa ntchito zida zamagetsi zomwe zili ndi magetsi omwewo. Dongosololi limapangidwa ndi ntchito yoteteza mopitilira muyeso kapena chip chili ndi ntchito yoteteza mopitilira muyeso, yomwe imatha kuzindikira mawonekedwe otsekedwa apano komanso afupiafupi ndikuyimitsa mwachangu chizindikiro chagalimoto. Kuphatikiza apo, varistor imatha kulumikizidwa ndi dera lamagalimoto kuti isapitirire kwakanthawi, ndipo capacitor yoyamwa imatha kupangidwa kumapeto kwa chipangizo chamagetsi.Mtundu uwu wa servo motor siwosavuta kuwotchamatabwa ozungulira ndi ma motors chifukwa cha kutsekeka kwa injini chifukwa cha kuphulika. Zilibe ubale weniweni ngati servo imapangidwa ndi mano achitsulo kapena mano apulasitiki.

4, Chifukwa chiyani servo imagwedezeka
The control dead zone ndi tcheru, ndipo zolowetsamo ndi zowunikira zimasinthasintha chifukwa cha zifukwa zosiyanasiyana, zomwe zimapangitsa kusiyana kupitilira kuchuluka kwake komanso mkono wowongolera kuyenda, zomwe zimapangitsa kuti chiwongolero chigwedezeke.

 

5, Kuzindikira zolakwika zonse za injini ya servo
1) Kuphulikako kutatha, injini ya servo inazungulira mwamphamvu, mkono wa rocker wheel unali wosalamulirika, ndipo mkono wa rocker unatsetsereka.

Zitha kuganiziridwa kuti zidazo zasesedwa ndikusinthidwa.
2) Pambuyo pa kuphulika, kugwirizana kwa servo motor kunachepa kwambiri. Chodabwitsa n'chakuti galimoto yowonongeka ya servo imakhala ndi kuyankha pang'onopang'ono komanso kutentha kwambiri, koma imatha kuthamanga ndi malangizo olamulira, koma kuchuluka kwa chiwongolero ndi kochepa kwambiri komanso pang'onopang'ono.

Mapeto oyambira: injini ya servo ili ndi overcurrent. Pambuyo pochotsa galimotoyo, zinapezeka kuti palibe katundu wamakono wa injiniyoapamwamba kwambiri (> 150MA), ndipo idasiya kugwira ntchito bwino (motor no-load yapano ≤ 60-90MA). Sinthani injini ya servo.
3) Pambuyo pa kuphulika, panalibe yankho kuchokera ku servo atatembenuza chiwongolero.
Kutsimikiza koyambira: Ngati dera lamagetsi la servo motor lathyoka, kukhudzana kuli koyipa, kapena gawo loyendetsa galimoto kapena dera la servo motor latenthedwa, choyamba yang'anani dera, kuphatikiza pulagi, kutsogolera kwa motor, ndi servo motor lead pazochitika zilizonse zotseguka. Ngati sichoncho, athetseni mmodzimmodzi. Choyamba, chotsani galimotoyo ndikuyesa panopa osanyamula katundu.

 

Ngati palibe katundu pano ndi wocheperapo90 MA, zikutanthauza kuti galimotoyo ndiyabwino, ndipo vutoli limayambitsidwa ndi servo motor drive kuwotcha. Pali 2 kapena 4 patch transistors pa 9-13g yaying'ono servo motor circuit board, yomwe ingasinthidwe. Ngati pali ma transistors awiri, ayenera kusinthidwa mwachindunji ndi Y2 kapena IY, ndiye kuti, SS8550. Ngati pali H-mlatho wozungulira ndi ma transistors anayi, akhoza kusinthidwa mwachindunji. Sinthani ndi 2 Y1 (SS8050) ndi 2 (SS8550) mwachindunji, UYR ya 65MG - gwiritsani ntchito Y1 (SS8050 IC=1.5A); UXR -- Sinthani mwachindunji ndi Y2 (SS8550, IC=1.5A).
4) Ngati injini ya servo ikulephera, mkono wa rocker ukhoza kuzungulira mbali imodzi osati kusuntha mbali inayo.
Chigamulo: servo motor ili bwino. Kuyang'ana kwakukulu kuli pagawo loyendetsa. N'zotheka kuti mbali imodzi ya transistor yoyendetsa galimoto yatenthedwa. Ikonzeni molingana ndi (3).

 

 

5) Pambuyo pokonza injini ya servo ndikuyitembenuza, inapezeka kuti galimoto ya servo inakakamira kumbali imodzi ndikupanga phokoso lomveka.
Kutsiliza: Zikuwonetsa kuti ma terminals abwino ndi oyipa a servo motor kapena mawaya omaliza a potentiometer amalumikizidwa molakwika. Ingosinthani njira yolumikizirana ndi ma mota awiri.

 
6) Nditagula injini ya servo yatsopano, ndidapeza kuti ikugwedezeka kwambiri ikayatsidwa, koma nditagwiritsa ntchito mkono wowongolera,zonse zinali zachilendo kwa servo motor.
Kutsiliza: Izi zikusonyeza kutiinjini ya servo idasonkhanitsidwa molakwikakapena kulondola kwa gear kunali kosakwanira pamene idachoka kufakitale. Vutoli nthawi zambiri limapezeka pazitsulo zama servo motors. Ngati simukufuna kuzibweza kapena kuzisintha, njira yodzithetsera ndikuchotsa chivundikiro chakumbuyo cha servo motor, kulekanitsa galimoto ya servo ku giya yochepetsera servo, finyani mafuta otsukira m'mano pakati pa magiya, ikani chivundikiro cha giya cha servo, ikani zomangira zochepetsera, ikani mkono wa rocker wa servo, ndikutembenuza giya la rocker mobwerezabwereza mpaka zida zachitsulo zimayendetsa zida zachitsulo. phokoso la mkangano limachepetsedwa. Mukatsuka giya la servo ndi petulo, ikani mafuta a silicone pa giya ndikusonkhanitsa injini ya servo kuti muthetse vuto la mota ya servo.

 
7) Pali mtundu wa servo wosagwira ntchito womwe umasonyeza khalidwe lachilendo: pamene chidziwitso chakutali chimayang'aniridwa ndi kugwedezeka, servo imakhala ndi yankho lachibadwa, koma pamene chidziwitso chakutali chikakhazikika pamalo enaake, mkono wolakwika wa servo ukugwirabe ntchito pang'onopang'ono, kapena ntchito ya mkono imakhala yaulesi ndikuyenda mmbuyo ndi mtsogolo.
Pambuyo kukonzanso kangapo, zidadziwika kuti vuto liri mu chogwirira chachitsulo cha potentiometer, chomwe chiyenera kumangirizidwa mwamphamvu mu gear yomaliza ya servo motor. Sichimalumikizidwa mwamphamvu ndi giya yayikulu (giya lomaliza) la mkono wa servo, komanso ngakhale kutsetsereka, zomwe zimapangitsaservo motor kuti isathe kupeza bwinolamulo la udindo loperekedwa ndi olamulira, zomwe zimapangitsa kuti pakhale ndemanga zolakwika ndi kufufuza kosalekeza.

 

Pambuyo pothetsa kugwirizana kolimba pakati pa potentiometer ndi rocker arm gear, vutolo likhoza kuthetsedwa. Ngati cholakwikacho chikadalipo pambuyo pokonza molingana ndi njirayo, ikhoza kukhalanso vuto ndi servo motor kapena potentiometer, yomwe imayenera kufufuzidwa mozama ndikufufuzidwa imodzi ndi imodzi!

 

8) Ngati servo yolakwika imangogwedezeka ndikuchotsa kusokoneza kwa wailesi, ndipo mkono wowongolera umagwedezekabe.
Kutsiliza: Potentiometer ikukalamba, isintheni, kapena ingoyisiyani ngati gawo lopuma!

 
9) Pambuyo kukhazikitsa servo ya digito yopendekera, zidapezeka kuti servo siyikuyenda bwino, ndikuthamanga kosiyanasiyana. Anabwezeredwa kwa wopanga ndipo ngakhale atasintha ndi atatu, kusasinthika kwake kunali koyipa.
Kutsiliza: Pambuyo pake anapeza kuti ma servos ena a digito amafuna BEC, ndipo atatha kukhazikitsa BEC yakunja ya 5. V3A, cholakwikacho chinathetsedwa, mosasamala kanthu za ubwino wa servos.
