Imigqa yokupakisha ihlukaniswa ngokuya nezici zokusabela zesistimu.
Umugqa wokuhlanganisa wokupakisha uhlelo lokulawula oluqhubekayo.
Amapharamitha oshintsho lwesistimu ayaqhubeka, okungukuthi, ukudluliselwa kwesignali yesistimu futhi impendulo yento elawulwayo iyinani eliqhubekayo elingaphazamiseki noma ubuningi be-analog.Ukulawula izinga lokushisa okukhulunywe ngakho ngaphambili, amasistimu okulawula isivinini sezimoto amasistimu okulawula aqhubekayo.Ngokuhambisana nobudlelwano phakathi kwenani lokuphumayo kanye nenani lokokufaka lesistimu, isistimu ingahlukaniswa yaba.
Isistimu yokulawula umugqa wokupakisha iqukethe izingxenye eziwumugqa, isixhumanisi ngasinye singachazwa ngesibalo esihlukanisayo somugqa ukuze kwenelise isimiso se-superposition, okungukuthi, lapho ukuphazamiseka okuningi noma izilawuli zisebenza ohlelweni ngesikhathi esifanayo, umphumela ulingana no isamba semiphumela ebangelwa isenzo ngasinye.
Isistimu yokulawula engaqondile yomugqa wokupakisha kwezinye izixhumanisi ezinokugcwaliswa kwesikhala, indawo efile, ukungqubuzana nezinye izici ezingezona umugqa, amasistimu anjalo avame ukuchazwa ngezibalo ezihlukene ezingezona umugqa, azihlangabezani nesimiso sokuma phezulu.
Isistimu yokulawula isikhashana yomugqa wokupakisha
Amasistimu okulawula aphakathi nendawo, aziwa nangokuthi amasistimu okulawula ahlukene, lapho amasiginali angaphakathi esistimu edlula kancane, angahlukaniswa abe.
(1) Amasistimu okulawula amasampula abonakala ngamadivayisi amasampula asampula amanani e-analogi aqhubekayo alawulwa ngefrikhwensi ethile futhi athumele amanani edijithali kukhompuyutha noma idivayisi ye-CNC.Ngemuva kokucubungula idatha noma ukukhohlisa, imiyalo yokulawula iyaphuma.Into elawulwayo ilawulwa ngokuguqula idatha yedijithali ibe idatha ye-analogue.Imvamisa yesampula ivame ukuba phezulu kakhulu kunemvamisa yoshintsho lwento.
(2) Uhlelo lokulawula lwesistimu yokulawula ukushintsha luqukethe izinto ezishintshayo.Njengoba izinto ezishintshayo “ZIVULIWE” kanye “NOVALIWE” kuphela ezifundeni ezimbili ezihluke ngokuphelele, azibonisi ngokuqhubekayo izinguquko kusiginali yokulawula ngakho-ke ukulawulwa okutholwe yisistimu kuyadingeka ngezikhathi ezithile.Amasistimu okulawula i-relay contactor, amasistimu wesilawuli ahlelekayo, njll. ashintsha amasistimu okulawula.Kunezinhlobo ezimbili zamasistimu okulawula ukushintsha: i-open-loop ne-closed-loop.I-Open-loop switching control theory isuselwe ku-logic algebra.
Ngokukhula kokuzenzakalela kwemigqa yokuhlanganisa yokupakisha, ukusebenza, ukugcinwa nokugcinwa okujwayelekile kwemishini yokupakisha nemishini kulula futhi kulula, kunciphisa amakhono ochwepheshe adingekayo kubaqhubi.Ikhwalithi yokupakishwa komkhiqizo ihlobene ngokuqondile nesistimu yokushisa, ukunemba kwesivinini sokusingatha, ukuzinza kwesistimu yokulandelela, njll.
Uhlelo lokulandelela luwumgogodla wokulawula wepayipi lokupakisha.Ukulandelela izindlela ezimbili ngaphambili nangemuva kusetshenziselwa ukuthuthukisa ukunemba kokulandelela.Ngemva kokuthi umshini ususebenza, inzwa yophawu lwefilimu ihlale ithola umaki wefilimu (ukufaka ikhodi yombala) kanye ne-microswitch yokulandelela engxenyeni yomshini ithola indawo yomshini.Ngemuva kokuthi uhlelo seluqalisiwe, zombili lezi zimpawu zithunyelwa ku-PLC.okukhiphayo kwe-PLC kulawula ukulandelela okuhle nokubi kwemoto yokulandelela, ethola ngokushesha amaphutha ezintweni zokupakisha ngesikhathi sokukhiqiza futhi yenza isinxephezelo esinembile nokulungiswa ukuze kugwenywe ukumoshwa kwezinto zokupakisha.Uma izidingo zobuchwepheshe zingakwazi ukuhlangatshezwana nazo ngemva kokulandelela inombolo enqunywe kusengaphambili yezikhathi, ingama ngokuzenzekelayo futhi ilinde ukuhlolwa ukuze igweme ukukhiqiza imikhiqizo engcolile;ngenxa yokwamukelwa kokulawulwa kwesivinini sokuguqulwa kwemvamisa, i-chain drive iyancipha kakhulu, okuthuthukisa ukuzinza nokuthembeka komshini futhi kunciphisa umsindo womshini.Iqinisekisa izinga eliphezulu lobuchwepheshe emshinini wokupakisha, njengokusebenza kahle okuphezulu, ukulahlekelwa okuphansi nokuhlola okuzenzakalelayo.
Nakuba umsebenzi wohlelo lokushayela olusetshenziswa emshinini wokupakisha ozenzakalelayo kanye nomugqa wokuhlanganisa ulula, ubeka izidingo eziphakeme ekusebenzeni okuguquguqukayo kokudluliswa, okudinga ukusebenza kokulandela okuguquguqukayo okusheshayo kanye nokunemba kwejubane eliphezulu elizinzile.Ngakho-ke kuyadingeka ukucabangela ukucaciswa okuguquguqukayo kwesiguquli sefrikhwensi nokukhetha isiguquli sokusebenza okuphezulu, esishintshashintshashintshayo nesisezingeni eliphezulu ukuze sihlangabezane nezimfuneko zomugqa wokupakisha oqhubekayo wesivinini esiphezulu.
