Inqubo yokusebenza yesistimu yokulawula ukushisa okuzenzakalelayo kwesithando somlilo esiyindilinga sokungeniswa kwensimbi
The working process of the temperature automatic control system of the round steel isithando sokushisa sangaphakathi
1. Ukukhethwa kwemodi yokulawula yesistimu yokulawula okuzenzakalelayo yesithando somlilo esiyindilinga sensimbi:
Imodi yokulawula yemishini ihlukaniswe yaba izindlela ezimbili zokusebenza: “okuzenzakalelayo” kanye “nokulawula okwenziwa ngesandla”. Ukushintsha kwezindlela ezimbili zokusebenza kukhethwa inkinobho yokukhetha imodi yokusebenza ku-console. Ngaphansi kwezimo ezizenzakalelayo, isistimu isethwe ukuthi ibe sendaweni “yokulawula mathupha”.
2. Ukulawulwa kwezinga lokushisa okuvaliwe kwe-loop yesistimu yokulawula okuzenzakalelayo yesithando somlilo esiyindilinga sensimbi:
Ngemuva kokuthi isistimu ingene ekukhethweni kwemodi yokulawula “okuzenzakalelayo”, izongena ngokuzenzakalelayo isixhumi esibonakalayo somshini womuntu. Ngemva kokufaka lesi sikhombimsebenzisi, ungafaka idatha ehambisanayo yokukhiqiza. Okokufaka kwedatha yokukhiqiza kungafakwa ngokuqondile kubhokisi ledatha lesixhumi esibonakalayo. Ngemva kokufakwa kwedatha, ungachofoza inkinobho yokuqala yokulawula okuzenzakalelayo; ngemva kokufaka isimo sokulawula okuzenzakalelayo, isimo sokulawula samanje sizoboniswa kubha yokusheshisa i-alamu. Ngemva kokungena esimweni sokulawula okuzenzakalelayo, uma kunezinkinga noma izinto ezingekho kumingcele yokukhiqiza okokufaka, uhlelo luzonikeza ngokushesha.
Ngemva kokufaka ukulawula okuzenzakalelayo, isistimu iqale ihlaziye idatha yokufaka bese isetha amandla okuqala ngokuya ngejika lobudlelwano phakathi kwemodeli yezibalo nezinga lokushisa lamandla. Lapho okungenalutho kuya endaweni yokulinganisa izinga lokushisa lapho uphuma khona, isistimu izohlaziya ukuthi inani lokushisa livamile yini noma cha. Bese kunqunywa amapharamitha we-PID wesistimu, futhi amandla okukhipha amandla okunikezwa kwamandla alungiswa ngokungahleliwe. Uhlelo lokusebenza kulokhu lufana nokulawulwa kwensimbi ehlakaniphile, ngakho-ke asikho isidingo sokungena emininingwaneni lapha. Ngakolunye uhlangothi, ngokokuhlangenwe nakho kokuhlola kwesikhathi eside kwenkampani yethu, ekulawuleni i-diathermy yokungeniswa, ukulungiswa kwe-PID kuphinde kwengeze indlela yephutha le-oda lesithathu lokuphinda kuxhaswe ngayo. Ithole imiphumela emihle kakhulu ngokwemibandela esebenzayo. Nqoba ngempumelelo i-overshoot yokuqala noma i-oscillation yokulungiswa kwe-PID.
