Imigca yokupakisha ihlelwa ngokweempawu zokusabela kwenkqubo.
Ukupakisha umgca wendibano eqhubekayo inkqubo yokulawula.
Iiparamitha kwinkqubo yokutshintsha ziyaqhubeka, oko kukuthi, ukuhanjiswa komqondiso wenkqubo kunye nokuphendula kwento elawulwayo yimali eqhubekayo engaphazamisekiyo okanye ubuninzi be-analog.Ulawulo lobushushu olukhankanywe ngaphambili, iinkqubo zokulawula isantya semoto ziinkqubo eziqhubekayo zokulawula.Ngokobudlelwane phakathi kobuninzi bemveliso kunye nobungakanani begalelo lenkqubo, inkqubo inokwahlulwa ibe.
Ukupakisha inkqubo yolawulo lomgca iqulathe amacandelo emgceni, ikhonkco ngalinye linokuchazwa nge-equation eyohlukileyo yomgca ukwanelisa umgaqo we-superposition, oko kukuthi, xa ii-perturbations ezininzi okanye ulawulo lusebenza kwinkqubo ngexesha elinye, isiphumo sisonke silingana isimbuku seziphumo ezibangelwa sisenzo ngasinye.
Umgca wokupakisha umgca wokuhlanganisa umgca wendlela yokulawula i-non-linear system kwezinye ikhonkco kunye ne-saturation, indawo efileyo, i-friction kunye nezinye iimpawu ezingenayo i-linear, iinkqubo ezinjalo zihlala zichazwe ngokulinganisa okungafaniyo okungafaniyo, akuhambelani nomgaqo we-superposition.
Umgca wokupakisha inkqubo yokulawula ephakathi
Iinkqubo zolawulo lwethutyana, ezikwabizwa ngokuba ziinkqubo zolawulo ezidityanisiweyo, apho imiqondiso yangaphakathi yenkqubo iphakathi, inokwahlulwa ibe.
(1) Iinkqubo zolawulo lwesampulu ziphawulwa ngezixhobo zesampulu ezenza isampulu yobuninzi be-analogue eqhubekayo elawulwa ngamaxesha athile kwaye ithumele imiyinge yedijithali kwikhompyuter okanye isixhobo se-CNC.Emva kokucubungula idatha okanye ukuguqulwa, imiyalelo yokulawula iphuma.Into elawulwayo ilawulwa ngokuguqula idatha yedijithali kwidatha ye-analogue.Ubuninzi besampulu buhlala buphezulu kakhulu kunokutshintsha kwento.
(2) Inkqubo yokulawula inkqubo yokulawula ukutshintsha iquka izinto zokutshintsha.Njengoko izinto zokutshintsha kuphela "ON" kwaye "OFF" kwiindawo ezimbini ezihluke ngokupheleleyo, azibonakali ngokuqhubekayo utshintsho kwisignali yokulawula kwaye ngoko ke ulawulo oluphunyezwe yinkqubo luyimfuneko.Iisistim eziqhelekileyo zokulawula i-relay contactor, iinkqubo zokulawula ezicwangcisiweyo, njl. zitshintsha iinkqubo zokulawula.Kukho iintlobo ezimbini zeenkqubo zokulawula ukutshintsha: i-open-loop kunye ne-closed-loop.Ithiyori yolawulo lokutshintsha iluphu evulekileyo isekwe kwi-logic algebra.
Ngokunyuka kwe-automation yemigca yendibano yokupakisha, ukusebenza, ukugcinwa kunye nokugcinwa kwesiqhelo koomatshini bokupakisha kunye nezixhobo kulula ngakumbi kwaye kulula, ukunciphisa izakhono zobungcali ezifunekayo kubaqhubi.Umgangatho wokupakishwa kwemveliso uhambelana ngqo nenkqubo yokushisa, ukuchaneka kwesantya somkhosi, ukuzinza kwenkqubo yokulandelela, njl njl.
Inkqubo yokulandelela ingundoqo yokulawula umbhobho wokupakisha.Ukulandelwa kweendlela ezimbini ngaphambili nangasemva kusetyenziselwa ukuphucula ngakumbi ukuchaneka kokulandelela.Emva kokuba umatshini uqhuba, i-sensor yophawu lwefilimu ihlala ibona uphawu lwefilimu (ikhowudi yombala) kunye ne-microswitch yokulandelela kwindawo yomatshini ibona indawo yomatshini.Emva kokuba inkqubo iqhutywe, zombini ezi mpawu zithunyelwa kwi-PLC.imveliso ye-PLC ilawula ukulandelela okulungileyo kunye nokubi kwemoto yokulandelela, efumanisa ngokukhawuleza iimpazamo kwizinto zokupakisha ngexesha lemveliso kwaye yenza imbuyekezo echanekileyo kunye nezilungiso ukuphepha ukuchithwa kwezinto zokupakisha.Ukuba iimfuno zobugcisa azikwazi ukuhlangabezana emva kokulandelela inani elimiselweyo lamaxesha, inokuyeka ngokuzenzekelayo kwaye ilinde ukuhlolwa ukwenzela ukuphepha ukuvelisa iimveliso zenkunkuma;ngenxa yokwamkelwa kokulawulwa kwesantya sokuguqulwa kwesantya, i-chain drive iyancipha kakhulu, ephucula ukuzinza kunye nokuthembeka komatshini kunye nokunciphisa ingxolo yomatshini.Iqinisekisa umgangatho ophezulu weteknoloji kumatshini wokupakisha, njengomsebenzi ophezulu, ukulahlekelwa okuphantsi kunye nokuhlolwa ngokuzenzekelayo.
Nangona umsebenzi wesicelo senkqubo yokuqhuba esetyenziselwa ukupakishwa okuzenzekelayo kunye nomgca wokuhlanganisa ulula, ubeka iimfuno eziphezulu ekusebenzeni okuguquguqukayo kokuhanjiswa, okudinga ukusebenza ngokukhawuleza kokulandelela okuguquguqukayo kunye nokuchaneka kwesantya esiphezulu esizinzile.Ngoko ke kuyimfuneko ukuqwalasela iinkcukacha eziguquguqukayo zomguquli we-frequency kunye nokukhetha ukusebenza okuphezulu, okuguquguqukayo kunye nomgangatho ophezulu wokuguqulela ukuhlangabezana neemfuno zomgca wokupakisha wemveliso oqhubekayo.
