Txheej txheem cej luam ntawm Model free Control rau Switching Power Supply
Nrog txoj kev loj hlob sai ntawm lub zog hluav taws xob thev naus laus zis, kev sib raug zoo ntawm cov khoom siv hluav taws xob hluav taws xob thiab tib neeg txoj haujlwm thiab lub neej tau dhau los ua ze, thiab cov khoom siv hluav taws xob tsis tuaj yeem ua yam tsis muaj lub zog muaj zog. Hloov fais fab mov yog ib hom khoom siv hluav taws xob uas siv cov cuab yeej hluav taws xob niaj hnub siv hluav taws xob los tswj lub sij hawm sib piv ntawm kev hloov cov transistors rau thiab tawm, thiab tswj cov zis hluav taws xob ruaj khov. Kev hloov hluav taws xob feem ntau yog tsim los ntawm pulse width modulation (pWM) tswj IC thiab MOSFET. Kev tswj ib feem ntawm kev hloov hluav taws xob hloov hluav taws xob feem ntau yog tsim thiab ua haujlwm raws li cov cim analog, tab sis qhov tsis zoo yog tsis muaj peev xwm tiv thaiv kev cuam tshuam. Vim muaj kev txhim kho sai ntawm kev tswj hwm lub tshuab computer, kev ua haujlwm thiab kev tswj ntawm cov teeb liab digital tau pom qhov zoo: kev ua haujlwm hauv computer yooj yim thiab kev tswj hwm, txhim kho kev tsim qauv yooj yim, thiab yooj yim software debugging, ua rau muaj qhov tshwm sim ntawm pID tswj.
Qhov tsis muaj kev tswj hwm tus qauv hauv kev hloov cov khoom siv hluav taws xob tau ua rau kev txhim kho cov khoom siv hluav taws xob digital, ntse, thiab ntau lub zog hloov khoom siv. Qhov no undoubtedly txhim kho kev ua tau zoo thiab kev ntseeg siab ntawm kev hloov hom fais fab khoom siv. Txawm li cas los xij, vim qhov tseeb tias cov khoom siv hluav taws xob hloov pauv yog cov khoom siv tsis yog hauv nruab nrab, nws yog qhov nyuaj heev los tsim cov qauv raug, uas feem ntau kwv yees. Tsis tas li ntawd, lawv cov khoom siv hluav taws xob thiab kev hloov pauv tsis paub meej. Yog li ntawd, kev siv cov kev tswj hwm analog lossis digital PID feem ntau ua rau nws nyuaj rau kev hloov pauv cov kev txwv ntawm PID maub los raws li, thiab kev tswj cov nyhuv tsis zoo tagnrho. Tus qauv tsim tawm tsis ntev los no kev tswj hwm dawb yog txoj kev tswj hwm pheej hmoo. Nws tsis cia siab rau tus qauv lej ntawm cov khoom tswj, sib xyaw ua qauv thiab kev tswj hwm, uas yog qhov tsim nyog rau qee qhov kev sib txawv thiab sib txawv lossis cov qauv tsis meej uas nyuaj rau piav qhia nrog cov qauv lej raug. Nws txhim kho kev tswj hwm ntawm kev hloov cov khoom siv hluav taws xob, tsis tsuas yog ua tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm siab thiab kev ntseeg siab ntawm kev hloov cov khoom siv hluav taws xob.
