Stepper lub cev muaj zog acceleration thiab deceleration tswj

Stepper lub cev muaj zogtxoj cai ua haujlwm
Feem ntau, lub rotor ntawm lub cev muaj zog yog cov hlau nplaum ruaj khov. Thaum tam sim no ntws los ntawm stator winding, lub stator winding tsim ib vector magnetic teb. Qhov no magnetic teb tsav lub rotor tig los ntawm ib lub kaum sab xis kom cov kev taw qhia ntawm lub rotor tus khub ntawm magnetic teb coincides nrog cov stator lub teb. Thaum lub vector magnetic teb ntawm stator tig los ntawm lub kaum sab xis.

Stepper lub cev muaj zogyog ib hom induction lub cev muaj zog, nws txoj hauv kev ua haujlwm yog kev siv hluav taws xob hauv hluav taws xob, qhov ncaj qha tam sim no rau hauv lub sijhawm sib koom siv hluav taws xob, ntau lub sij hawm tswj tam sim no, nrog rau qhov tam sim no rau stepper lub cev muaj zog fais fab mov, stepper lub cev muaj zog tuaj yeem ua haujlwm tau zoo, tus tsav tsheb yog rau stepper lub sijhawm sib koom fais fab mov, multiphase timeing controller.

Txhua lub tswv yim hluav taws xob pulse, lub cev muaj zog tig lub kaum sab xis rau ib kauj ruam. Nws cov zis angular displacement yog proportional rau tus naj npawb ntawm pulses input, ceev yog proportional rau mem tes zaus. Hloov qhov kev txiav txim ntawm winding energization, lub cev muaj zog yuav thim rov qab. Yog li koj tuaj yeem tswj cov naj npawb ntawm cov pulses, zaus thiab qhov kev txiav txim ntawm energizing txhua theem ntawm lub cev muaj zog winding los tswj cov kev sib hloov ntawm stepper lub cev muaj zog.

Qhov tseeb ntawm qhov dav dav stepper lub cev muaj zog yog 3-5% ntawm lub kaum sab xis, thiab nws tsis sib sau.

Lub torque ntawm lub stepper lub cev muaj zog yuav txo qis raws li qhov ceev nce. Raws li lub stepper lub cev muaj zog rotates, inductance ntawm txhua theem ntawm lub cev muaj zog winding yuav tsim ib tug rov qab fais fab; qhov siab dua qhov zaus, qhov ntau dua qhov rov qab hluav taws xob muaj peev xwm. Nyob rau hauv nws qhov kev txiav txim, lub cev muaj zog nrog lub zaus (los yog ceev) nce thiab cov theem tam sim no txo, uas ua rau txo qis torque.

Stepper lub cev muaj zog tuaj yeem ua haujlwm ib txwm nyob ntawm qhov qis qis, tab sis yog tias siab tshaj qhov ceev yuav tsis pib, thiab nrog lub suab ntxhi.

Stepper lub cev muaj zog muaj ib qho kev ntsuas: tsis muaj load pib zaus, uas yog, lub stepper lub cev muaj zog nyob rau hauv cov ntaub ntawv ntawm tsis muaj-load mem tes zaus yuav pib ib txwm, yog hais tias tus mem tes zaus siab tshaj tus nqi, lub cev muaj zog tsis tuaj yeem pib ib txwm, tej zaum yuav tshwm sim tawm ntawm kauj ruam los yog thaiv.

Nyob rau hauv cov ntaub ntawv ntawm ib tug load, qhov pib zaus yuav tsum qis dua. Yog hais tias lub cev muaj zog yuav tsum tau ua kom muaj kev sib hloov ceev ceev, cov mem tes zaus yuav tsum muaj cov txheej txheem acceleration, piv txwv li, qhov pib zaus qis dua, thiab tom qab ntawd nce mus rau qhov xav tau siab zaus (lub cev muaj zog los ntawm qis qis mus rau kev kub ceev) ntawm qee qhov acceleration.

Vim li cas uastepper motorsyuav tsum tau tswj nrog ceev txo
Qhov ceev ntawm lub tshuab stepper yog nyob ntawm qhov zaus ntawm cov mem tes, tus naj npawb ntawm cov hniav rotor thiab tus naj npawb ntawm cov neeg ntaus. Nws angular ceev yog proportional rau mem tes zaus thiab synchronized nyob rau hauv lub sij hawm nrog lub mem tes. Yog li, yog tias tus naj npawb ntawm cov hniav rotor thiab tus naj npawb ntawm cov neeg ntaus khiav yog qhov tseeb, qhov xav tau ceev tuaj yeem tau los ntawm kev tswj cov mem tes zaus. Txij li thaum lub stepper lub cev muaj zog pib nrog kev pab los ntawm nws cov synchronous torque, qhov pib zaus tsis siab kom tsis txhob poob kauj ruam. Tshwj xeeb tshaj yog thaum lub zog nce, lub rotor txoj kab uas hla nce, qhov inertia nce, thiab qhov pib zaus thiab qhov siab tshaj plaws khiav zaus yuav txawv ntawm ntau npaum li kaum zaug.

Cov yam ntxwv pib zaus ntawm stepper lub cev muaj zog kom lub stepper lub cev muaj zog pib tsis tuaj yeem ncaj qha mus txog qhov kev khiav hauj lwm zaus, tab sis kom muaj cov txheej txheem pib, uas yog, los ntawm qhov qis qis maj mam nce mus rau kev khiav hauj lwm ceev. Nres thaum qhov kev khiav hauj lwm zaus tsis tuaj yeem poob tam sim ntawd mus rau xoom, tab sis kom muaj kev kub ceev gradual txo mus rau xoom txheej txheem.

Yog li ntawd, kev khiav hauj lwm ntawm stepper lub cev muaj zog feem ntau yuav tsum mus los ntawm lub acceleration, uniform ceev, deceleration peb theem, acceleration thiab deceleration txheej txheem kom luv li sai tau, lub sij hawm ceev ceev kom ntev li ntev tau. Tshwj xeeb tshaj yog nyob rau hauv kev ua hauj lwm xav tau kev teb ceev ceev, lub sij hawm yuav tsum tau khiav ntawm qhov pib taw tes mus rau qhov kawg yog luv tshaj plaws, uas yuav tsum tau lub shortest txheej txheem ntawm acceleration thiab deceleration, thiab lub siab tshaj plaws ceev ntawm tas li ceev.

Acceleration thiab deceleration algorithm yog ib qho ntawm cov thev naus laus zis tseem ceeb hauv kev tswj cov lus tsa suab, thiab yog ib qho tseem ceeb kom ua tiav kev kub ceev thiab kev ua haujlwm siab. Hauv kev tswj hwm kev lag luam, ntawm ib sab, cov txheej txheem ntawm kev ua tiav yuav tsum ua kom du thiab ruaj khov, nrog rau kev cuam tshuam me me; ntawm qhov tod tes, nws xav tau lub sijhawm teb sai thiab cov tshuaj tiv thaiv sai. Nyob rau hauv lub hauv paus ntawm kev ua kom muaj kev tswj xyuas qhov tseeb los txhim kho kev ua tau zoo, kom ua tiav kev ua haujlwm zoo thiab ruaj khov, yog qhov kev lag luam tam sim no tau los daws qhov teeb meem tseem ceeb. Lub acceleration thiab deceleration algorithms feem ntau siv nyob rau hauv tam sim no kev tswj lub tshuab feem ntau muaj xws li: trapezoidal nkhaus acceleration thiab deceleration, exponential nkhaus acceleration thiab deceleration, S-shaped nkhaus acceleration thiab deceleration, parabolic nkhaus acceleration thiab deceleration, thiab lwm yam.

Trapezoidal nkhaus acceleration thiab deceleration
Txhais: Acceleration / deceleration nyob rau hauv ib tug linear yam (acceleration / deceleration los ntawm qhov pib ceev mus rau lub hom phiaj ceev) nrog ib tug tej yam piv

Kev suav cov mis: v(t)=Vo+at

Qhov zoo thiab qhov tsis zoo: Trapezoidal nkhaus yog tus cwj pwm los ntawm kev yooj yim algorithm, siv sijhawm tsawg dua, cov lus teb ceev ceev, kev ua haujlwm siab thiab kev siv yooj yim. Txawm li cas los xij, cov txheej txheem acceleration thiab deceleration tsis ua raws li txoj cai ntawm stepper lub cev muaj zog hloov ceev, thiab qhov kev hloov pauv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov ceev tsis tuaj yeem ua tau zoo. Yog li ntawd, qhov algorithm no tsuas yog siv rau hauv cov ntawv thov uas qhov yuav tsum tau ua rau cov txheej txheem acceleration thiab deceleration tsis siab.

Exponential nkhaus acceleration thiab deceleration
Txhais: Nws txhais tau tias acceleration thiab deceleration los ntawm exponential muaj nuj nqi.

Acceleration thiab deceleration tswj kev ntsuam xyuas Performance index:
1, Tshuab trajectory thiab txoj hauj lwm yuam kev yuav tsum me me li sai tau

2 、 Cov txheej txheem tshuab ua haujlwm yog du, jitter me me, thiab cov lus teb ceev ceev

3, acceleration thiab deceleration algorithm yuav tsum yooj yim li sai tau, yooj yim rau siv, thiab muaj peev xwm ua tau raws li cov cai tswj lub sijhawm.
