Kudzora kwemaindasitiri kunonyanyopatsanurwa kuita mativi maviri.Imwe inodzora kufamba, iyo inowanzoshandiswa mumunda wemakanika;Imwe yacho ndeye process control, iyo inowanzo shandiswa muindasitiri yemakemikari.Iyo yekufamba inodzora inoreva rudzi rwe servo system yakatanga munhanho yekutanga, iyo yakavakirwa pakutonga kwemota kuona kutonga kwekuchinja kwehuwandu hwemuviri senge diagonal displacement, torque, kumhanya, nezvimwe zvechinhu. .
Kubva padanho rekunetsekana, chinonyanya kunetsa che servo mota ndechekudzora imwe kana anopfuura ma paramita mu torque, kumhanya uye chinzvimbo chemota imwe chete kuti isvike kukosha kwakapihwa.Chakanyanya kutariswa chekufamba kutonga ndechekubatanidza akawanda mota kuti apedze iyo yakatsanangurwa kufamba (synthetic trajectory, synthetic kumhanya), nekusimbisa kwakawanda pakuronga trajectory, kukurumidza kuronga, uye kinematics shanduko;Semuyenzaniso, iyo XYZ axis mota inofanirwa kurongeka muCNC muchina chishandiso kupedzisa kupindira kwekuita.
Kudzora mota kunowanzo kutariswa sechinhu chinongedzo chekufamba kudzora system (kazhinji ikozvino loop, kushanda mu torque modhi), iyo inotarisa zvakanyanya pakutonga kwemota, kazhinji inosanganisira kutonga kwenzvimbo, kukurumidza kudzora uye torque control, uye kazhinji haina kuronga. kugona (vamwe vatyairi vane chinzvimbo chakareruka uye nekumhanyisa kuronga kugona).
Motion control inowanzoenderana nezvigadzirwa, zvinosanganisira mechanical, software, magetsi uye mamwe mamodules, akadai semarobhoti, unmanned aerial vehicles, motion platforms, etc. Imhando yekudzora kudzora uye kubata chinzvimbo uye kumhanya kwema mechanical kufamba zvikamu mu. nguva chaiyo, kuitira kuti vagone kufamba zvinoenderana neinotarirwa inofamba trajectory uye yakatarwa mafambiro paramita.
Zvimwe zvezviri mukati mezviviri izvi zvakangofanana: iyo chinzvimbo loop / yekumhanyisa loop / torque loop inogona kuoneka mumutyairi wemota kana mune inofamba controller, saka izvo zviviri zviri nyore kuvhiringidzika.Iyo yekutanga dhizaini yekufamba inodzora sisitimu inosanganisira: inofamba controller: inoshandiswa kugadzira trajectory mapoinzi (inodiwa inobuda) uye yakavharwa nzvimbo mhinduro loop.Mazhinji ma controller anogona zvakare kuvhara yekumhanyisa loop mukati.
Motion controllers inonyanya kukamurwa kuita zvikamu zvitatu, zvinoti PC-yakavakirwa, yakatsaurirwa controller uye PLC.PC-based motion controller inoshandiswa zvakanyanya mumagetsi, EMS uye mamwe maindasitiri;Iwo anomiririra maindasitiri eakakosha controller isimba remhepo, photovoltaic, robhoti, molding michina, nezvimwe;PLC inozivikanwa mune rabha, mota, metallurgy uye mamwe maindasitiri.
Dhiraivha kana amplifier: inoshandiswa kushandura chiratidzo chekudzora (chinowanzo mhanyisa kana torque chiratidzo) kubva kune chinofambisa chinodzora kuita chepamusoro simba ikozvino kana voltage chiratidzo.Iyo yakawedzera hungwaru dhiraivha inogona kuvhara iyo chinzvimbo loop uye yekumhanyisa loop kuti iwane kutonga kwakaringana.
Actuator: senge hydraulic pombi, silinda, linear actuator kana mota yekubuda kufamba.Feedback sensor: senge photoelectric encoder, rotary transformer kana Hall-effect mudziyo, unoshandiswa kupindura chinzvimbo cheactuator kune chinzvimbo chekutonga kuti uwane kuvhara kweiyo chinzvimbo chekudzora loop.Mazhinji emakanika mamesheni anoshandiswa kushandura iyo yekufambisa fomu yeactuator kuita yaunoda inofamba fomu, kusanganisira giya bhokisi, shaft, bhora screw, mazino bhandi, coupling uye linear uye rotary mabheji.
Kubuda kwekutonga kwekufamba kunowedzera kukurudzira mhinduro ye electromechanical control.Semuenzaniso, munguva yakapfuura, makamera uye magiya aifanirwa kuoneswa nemuchina dhizaini, asi ikozvino anogona kuitika nekushandisa emagetsi cams uye magiya, kubvisa kudzoka, kupokana uye kupfeka mukuita kwekuita mechanical realization.
Zvigadzirwa zvemature motion control hazvingofanire kupa kuronga nzira, kudzora kumberi, kurongeka kwekufamba, kududzira, kumberi uye inverse kinematics mhinduro uye kuraira kubuda kwemota mota, asi zvakare inoda kuve neinjiniya yekumisikidza software (yakadai SCOUT yeSIMIMOTION), muturikiri we syntax. (isingarevi mutauro wayo chete, asi zvakare inosanganisira PLC mutauro werutsigiro weIEC-61131-3), iri nyore PLC basa, PID control algorithm kuita, HMI inopindirana interface, uye kukanganisa kuongororwa interface, Yepamberi yekufambisa controller inogona zvakare kuona kuchengetedza kuchengetedza.
