Lub teeb liab ua haujlwm sawv cev rau tswj kev tswj hwm ntawm lub voj voog tswjthiab sib npaug rau cov lej ntawm cov lej ntawm cov khoom siv siv hluav taws xob thiab cov lus qhia tawm tswv yim. Qhov no tseem hu ua "kev ua yuam kev."
Yuav ua li cas yuam kev ntawm lub teeb liab?
A lub teeb liab tsim los ntawm tus maub los sib npaug ntawm qhov sib txawv ntawm qhov teeb tsa thiab lub sensor muab cov ntaub ntawv.
Dab tsi yog qhov kev qhia rau kev tswj xyuas yuam kev?
Function of the Integral Term
Controller yuam kev yog e(t)=SP – PV.
Dab tsi yog summing point?
Lub ntsiab lus xaus yog sawv cev nrog ib lub voj voog muaj hla (X) hauv nws. Nws muaj ob los yog ntau tshaj inputs thiab ib qho tawm. Nws tsim cov algebraic sum ntawm cov inputs. Nws kuj ua qhov summation los yog rho los yog ua ke ntawm summation thiab rho tawm ntawm cov inputs raws li polarity ntawm inputs.
Dab tsi yog qhov system thaiv daim duab?
Ib daim duab thaiv yog daim duab ntawm lub kaw lus uas lub ntsiab lus lossis kev ua haujlwm tau sawv cev los ntawm cov blocks txuas nrog cov kab uas qhia txog kev sib raug zoo ntawm cov blocks. Lawv tau siv ntau hauv engineering hauv kev tsim kho vajtse, tsim hluav taws xob, tsim software, thiab cov txheej txheem ntws.
