Muindasitiri yemarobhoti, servo madhiraivha inyaya yakajairika.Nekukurumidza shanduko yeIndasitiri 4.0, iyo servo drive yerobhoti yakakwidziridzwa zvakare.Iyo yazvino marobhoti sisitimu haingodi dhiraivha system kudzora akawanda mbezo, asi zvakare kuwana mamwe mabasa akangwara.
Pane imwe neimwe node mukushanda kweakawanda-axis indasitiri robhoti, inofanira kushandisa masimba ehukuru hwakasiyana mumativi matatu kupedzisa mabasa akadai sekubata kubata. The motorsmumarobhoti variinokwanisa kupa shanduko yekumhanya uye torque panzvimbo chaidzo, uye mutongi anozvishandisa kuronga mafambiro pamwe nematemo akasiyana, zvichiita kuti anyatso kumira.Mushure mekunge robhoti yapedza basa rekubata, mota inodzikisa torque ichidzosera ruoko rwerobhoti kunzvimbo yayo yekutanga.
Inoumbwa neyepamusoro-inoshanda kudzora chiratidzo kugadzirisa, chaiyo inductive mhinduro, magetsi ekupa, uye hungwarumotokari inotyaira, iyi yepamusoro-inoshanda servo systeminopa yakaomesesa pedyo-pakarepo mhinduro chaiyo yekumhanya uye torque control.
High-speed real-time servo loop control-control signal processing uye inductive mhinduro
Hwaro hwekuona yakakwirira-yekukurumidza dhijitari chaiyo-nguva kutonga kwe servo loop haiparadzaniswe kubva mukukwidziridzwa kweiyo microelectronics yekugadzira maitiro.Tichitora iyo yakajairwa-chikamu chemagetsi-inoshanda robhoti mota semuenzaniso, PWM-nhatu-chikamu inverter inogadzira yakakwira-frequency pulsed voltage waveforms uye inoburitsa aya waveforms mumatatu-chikamu mamhepo emota muzvikamu zvakazvimirira.Pakati pemasaini matatu emagetsi, shanduko mumutoro wemotor inokanganisa mhinduro yazvino inonzwika, inodhindwa, uye inotumirwa kudhijitari processor.Iyo digitaalinen processor inobva yaita yakakwirira-kumhanya chiratidzo chekugadzirisa algorithms kuti uone zvinobuda.
Kwete chete kuita kwepamusoro kwedhijitari processor inodiwa pano, asi kune zvakare yakasimba dhizaini zvinodiwa kune magetsi.Ngatitarisei chikamu che processor kutanga. Iyo yakakosha komputa yekumhanyisa inofanirwa kuenderana nekumhanya kweotomatiki kukwidziridzwa, iyo isisiri dambudziko.Mamwe machipisi ekudzora opareshenibatanidza maA/D converters, nzvimbo/speed monitoring multiplier counters, PWM generator, etc. zvinodiwa kuti motor control with the processor core, iyo inopfupisa zvikuru sampling nguva ye servo control loop uye inowanikwa nekamwe chip. Iyo inotora otomatiki kukwidziridza uye kudzikisira kudzora, giya kuwiriranisa kutonga, uye dhijitari muripo wekutonga kwematatu zvishwe zvechinzvimbo, kumhanya uye zvazvino.
Kudzora maalgorithms akadai sevelocity feedforward, kukwidziridza feedforward, yakaderera-pass kusefa, uye sag kusefa inoiswawo pane imwechete chip.Kusarudzwa kwe processor hakuzodzokororwe pano. Muzvinyorwa zvakapfuura, zvakasiyana-siyana marobhoti zvikumbiro zvakaongororwa, ingave iri yakaderera-mutengo application kana application ine yakakwira zvinodiwa pakuronga uye algorithms. Pakatova nesarudzo dzakawanda pamusika. Zvakanakira zvakasiyana.
Kwete chete mhinduro yazvino, asi imwe data yakanzwa inotumirwawo kune controller kuti itarise shanduko musystem voltage uye tembiricha. Yakakwirira-resolution ikozvino uye voltage sensing mhinduro yagara iri dambudziko mukatimota control. Kutsvaga mhinduro kubva kune ese shunts / Hall sensors/ magineti sensors panguva imwe chete pasina mubvunzo ndiyo yakanyanya kunaka, asi izvi zvakanyanya kudiwa padhizaini, uye simba rekombuta rinoda kuenderera.
Panguva imwecheteyo, kuitira kuti udzivise kurasikirwa kwechiratidzo uye kupindira, chiratidzo chacho chinodhindwa pedyo nemucheto we sensor. Sezvo mwero wesampling uchiwedzera, kune akawanda data zvikanganiso zvinokonzerwa nesignal drift. Dhizaini inoda kutsiva shanduko idzi kuburikidza neinduction uye algorithm kugadzirisa.Izvi zvinobvumira iyo servo system kuti irambe yakagadzikana pasi pemamiriro akasiyana.
Yakavimbika uye chaiyo servo drive-simba rekupa uye nehungwaru mota dhiraivha
Magetsi ane ultra-high-speed switching mabasa ane yakagadzikana yakakwirira-resolution control simba rakavimbika uye rakarurama servo control. Parizvino, vazhinji vanogadzira vakabatanidza ma modules emagetsi vachishandisa high-frequency materials, izvo zviri nyore kugadzira.
Switch-mode magetsi ekushandisa anoshanda mu controller-based closed-loop power supply topology, uye maviri anowanzo shandiswa switch switch imagetsi MOSFETs uye IGBTs.Madhiraivha emagedhi akajairwa mumasisitimu anoshandisa switch-mode magetsi emagetsi anodzora voltage uye azvino pamagedhi ema switch aya nekudzora ON/OFF state.
Mukugadzirwa kwemagetsi e-switch-mode uye matatu-phase inverters, akasiyana-siyana epamusoro-akangwara emagedhi madhiraivha, madhiraivha ane akavakirwa-mukati maFET, uye madhiraivha ane akabatanidzwa anodzora mabasa anobuda murukova rusingaperi.Iyo yakabatanidzwa dhizaini yakavakirwa-muFET uye yazvino sampling basa inogona kuderedza zvakanyanya kushandiswa kwekunze kwezvikamu. Iyo logic kumisikidzwa yePWM uye inogonesa, yepamusoro uye yakaderera transistors, uye Horo chiratidzo chekuisa inowedzera zvakanyanya kuchinjika kwedhizaini, iyo isingarerutse maitiro ebudiriro, asi zvakare inovandudza Masimba Masimba.
Servo mutyairi ICs zvakare anowedzera mwero wekubatanidza, uye yakanyatsobatanidzwa servo mutyairi ICs inogona kupfupisa zvakanyanya nguva yekusimudzira yeakanakisa simba rekuita kwe servo masisitimu.Kubatanidza iyo pre-mutyairi, sensing, edziviriro maseketi uye bhiriji remagetsi mupakeji imwe kunoderedza kushandiswa kwesimba rose uye mutengo wehurongwa.Yakanyorwa pano ndeye Trinamic (ADI)'s yakazara yakazara servo mutyairi IC block diagraph, ese ekutonga mabasa anoitwa muhardware, yakabatanidzwa ADC, chinzvimbo sensor interface, chinzvimbo interpolator, inoshanda zvizere uye yakakodzera kune akasiyana servo application.
