DC Servo Lub Cev Muaj Zog Tswj
DC servo motor muaj ceev teb, ceev ceev stability, dav ceev ntau thiab lwm yam ntxwv, uas yog feem ntau siv rau kev rov qab system uas yuav tsum tau ua tiav yog qhov tswj ceev thiab kev tswj kev tswj.Nws yog dav siv hauv industrial, national tiv thaiv thiab civil cov chaw haujlwm, tshwj xeeb tshaj yog nyob rau hauv kev ua haujlwm rau cov tubrog nkoj, kev tsav tsheb, radar antennas, neeg hlau tswj thiab lwm lub sijhawm. Txawm li cas los, txoj kev loj hlob ntawm AC servo tsav ceev ceev, tab sis nyob rau cov chaw no nyuaj hloov lub DC servo engine.
Cov kev cai DC tswj lub cev muaj xws li ob lub tswv yim loops, namely, kev voj voj thiab cov voj tam sim no, siv ceev
tachometer, cuab tam siv tam sim no (Cov cuab yeej tam sim no) thiab cov hluav taws xob hauv hluav taws xob analog hluav taws xob kom ua tiav cov kev ceev-voj kev tswj.Los ntawm digital DC servo tswj siv high-speed cov teeb liab processor (DSP), ncaj qha coj mus kuaj ntawm qhov ceev thiab tam sim no teeb liab, kom ua tiav cov kev sib piv, cov kev hloov kho digital (digital filtering), digital pulse dav tes taws los piav thiab lwm yam kev khiav dej num, thaum kawg achie thiab leej tswj kev ceev.Compared nrog ob, analog ceev tswj qhov muaj qhov zoo ntawm cov qauv yooj yim, luv nqi thiab siab kev ywj pheej, tab sis qhov debugging ntau nyuab vim qhov kev hloov kho ntawm Circuit Court tsis feem ntau yuav tsum kho vajtse hloov.Qhov digital ceev tswj qhov yog complex thiab kim, tab sis ceev kev kho lus yog siab heev, tus txheej txheem debugging kuj yooj yim, qhov kev kawm ntawm cov kev ceev tswj lub cev tswj tau los ntawm software.
Cov nram qab no qhia txog ib txoj kev, nruab nrab ntawm cov analog ceev thiab cov digital ceev, uas yog, siv cov khoom pabcuam analog
(ISPPAC10) after analog ceev tswj qhov system, qhov system circuit tsis tau kho los ntawm software, thiab simulate tau
tsim System qauv.Qhov no hom txhim kho lub CCD lub koob yees duab tsis siv lub kaw lus ntawm tus thawj DC Governor, thiab ua tiav cov txiaj ntsig zoo.
Txoj kab tswj analog ceev tswj feem ntau yog li ntawm ob lub voj-voj kaw, lub voj kev kaw ceev ceev thiab lub voj kev kaw tam sim no,
nyob rau hauv thiaj li yuav pab kom ob leeg sib koom ua ke, ua si lub luag haujlwm, teeb tsa ob tus neeg tswj hwm hauv qhov system, muab kho qhov ceev thiab tam sim no.Tus ob lub tswv yim kaw voj qauv siv lub nplhaib nrog lub nplhaib ntawm nested qauv, uas yog thiaj li hu ua ob chav kaw-voj kev ceev tswj lawv.Nws muaj dynamic response ceev, anti-cuam tshuam muaj peev xwm thiab thiaj on, yog li tau lug siv.
Nyob hauv txoj kev debugging ntawm analog ceev tswj qhov system, vim muaj lub cav tsis muaj zog los yog thauj cov khoom siv dag zog nrog qhov theoretical qhov tseem ceeb heev, feem ntau yuav tsum hloov cov R, C thiab lwm yam khoom los hloov qhov CircuitE tsis tau txais kev ua tiav kev ua tau zoo , nws yog qhov teeb meem loj heev.Yog hais tias siv lub tshuab pabcuam analog los ua tus tswj cov cai tswj, qhov system tsis xws li kev nce, bandwidth thiab txawm circuit qauv hloov los ntawm software, debugging yog yooj yim heev.
Programmable analog li tau yooj yim tsim thiab simulate circuits.With nws tsim simulation ceev Circuit Court, tus Circuit Court tsis, tus qauv yuav tsum tom los ntawm software, ua tus txheej txheem debugging ua yooj yim heev.Nws yuav tsum tau muab sau tias hom ntaus ntawv kev khiav hauj lwm voltage feem ntau tsis tshaj 5V.
