Ngezinzwa ezininzi kunye neesekethe zokujonga, umsebenzi unokuba nzima - kulapho i-cascade ingena khona.
I-Cascading yinkqubo yokuvula okanye ukucima ezinye izixhobo ngokusekelwe ekubeni isixhobo sangaphambili senziwe sasebenza.
Ikhusela ukusebenza ngaphandle kokulandelelana kunye nokusebenza ngokungazinzanga ngokuvumela kuphela inzwa enye ngexesha kwindlela yesiphaluka ukuze isebenze xa kufuneka yenzeke.

Yintoni ulawulo lwe-cascade oluchaza ngomzekelo?
Ulungiselelo lolawulo lwe-cascade yindlela yokugcina amanqanaba amaninzi angatshintshiyo, kwaye isiphumo somlawuli omnye siqhuba indawo yokumisela yenye.
Umzekelo: Umlawuli wenqanaba oqhuba isilawuli sokuhamba ukuze bobabini babe nexabiso labo elifunekayo endaweni yokulawula inqaku elinye okanye amabini kubalawuli babo.
Lusebenza njani ulawulo lwe-cascade?
Ulawulo lwe-Cascade luhlobo lwe-loop yempendulo apho imveliso evela kumlawuli omnye inika igalelo kwelinye.
Ngale nkqubo, iziphazamiso kujongwana nazo ngokulula ngakumbi kuba ukuba kukho umba ngenxalenye enye yenkqubo (umz., iye ishushu kakhulu), ngoko kuphela elo candelo kufuneka lilungiswe kunokuba yonke inkalo yemveliso ivalwe kwaye iqalwe kwakhona. kanye njengangaphambili xa abantu beza kuvala nje bonke oomatshini ngelixa besebenza ekufumaneni into engalunganga ngeeyure okanye iintsuku ngexesha de umntu ekugqibeleni acinge indlela yokulungisa nayiphi na ingxaki eyenzekileyo.
Kutheni sisebenzisa ulawulo lwe-cascade?
Ukulawulwa kweCascade yinkqubo efuna ukuphucula ukusebenza ngokunciphisa imiphumo yokuphazamiseka. Ngokusebenzisa ukuguquguquka kwesilumkiso kwangaphambili, i-Cascade Control inokuthintela okanye ukunciphisa iimpembelelo ezimbi kwiinkqubo kunye neemveliso ngenxa yokuphazamiseka okufana nokuchithwa komatshini kunye nokunqongophala kwezinto.
Ngokuthintela iingxaki ngaphambi kokuba zenzeke ngokulawula izinto eziguquguqukayo eziphambili kwangaphambili, uLawulo lweCascade lunceda abasebenzisi ukuba baphephe iziganeko eziphazamisayo ezifana nokusilela kwezixhobo okanye ukuphelelwa kwezinto.
Ufunde kwakhona: ukuba ufuna ukugrumba umngxuma kwintsimbi engatyiwayo, ezi ziisarha zomngxuma oya kufuna ukuzithenga.
Zeziphi iingenelo kunye nokungalunganga kulawulo lwe-cascade?
Ukulawulwa kweCascade yindlela yokwala ukuphazamiseka okunemiqobo yayo. Enye i-drawback kulawulo lwe-Cascade yimfuneko yomlinganiselo owongezelelweyo (umlinganiselo wokuhamba ngesiqhelo) ukuze usebenze ngokufanelekileyo, kunye nezithintelo ezimbini kukho umlawuli omnye ofunekayo, onokuba yingxaki kuba unabalawuli abaninzi abanee-tunings ezahlukeneyo.
Ewe ayizizo zonke izinto ezingeloncedo ezodlula iingenelo xa kufikwa kwiindlela zokuyila ezinje kodwa ezi zintathu ngokuqinisekileyo zibangela ezinye iingxaki-ukuqinisekisa ukuba iinjineli ziculela yonke into ngendlela eyiyo kuba nzima ngaphandle kwamava aneleyo okanye ixesha ezandleni zabo!
Ngaba i-cascade control feed forward?
Ulawulo lwe-feedforward yindlela esebenzayo yokuphelisa ukuphazamiseka ngaphambi kokuba kube nemiphumo emibi kwinkqubo. Ngokungafaniyo nolawulo lwe-cascade, olulinganisa ukuba benze kakuhle kangakanani kwaye banokuphendula kuphela ukuphazamiseka komntu ngamnye okuchaphazela ukuguquguquka kwabo okulawulwayo, i-feedforward ithathela ingqalelo eminye imiba nayo ukuze ingabanjwa ingalungiselelanga xa ijongene nemingeni emitsha.
Yeyiphi eyona milinganiselo iphantsi yokuphumelela kwenkqubo yokulawula i-cascade?
Ukuqinisekisa ukuba i-cascade iyimpumelelo, inkqubo yesilumkiso kwangethuba i-PV2 kufuneka ikwazi ukuphendula phambi kwe-PV1 engundoqo yangaphandle zombini xa kukho ukuphazamiseka kwenkxalabo (D2) nanjengoko isabela kulawulo lokugqibela lobuchule.
Zisetyenziswa phi iisekethe ze-cascade?
Iisekethe zeCascade yindlela ekrelekrele yokwenza okuninzi ngamanyathelo ambalwa kakhulu. Oku kungenxa yokuba bavumela abenzi boluvo kunye neesekethe eziphuma ngokulandelelana, eziya kuba yintlekele kwiindidi ezininzi zezixhobo ezinjengeefriji okanye imigca yemveliso yemizi-mveliso. Iisekethe zeCascade ziqinisekisa ukhuseleko lwaba matshini ngokuvula kunye nokucima iziqwenga ezahlukeneyo njengoko kufuneka ukuze yonke into isebenze kakuhle kanye!
Uyilungisa njani inkqubo yokulawula i-cascade?
I-Tuning Cascade Loops: Kukho iindlela ezimbini zokulungisa i-cascade loops. Eyokuqala kukulungisa abalawuli bekhoboka ngabanye njenge-loop ye-PID eqhelekileyo kwaye emva koko uhlengahlengiso iiparamitha zomlawuli oyintloko ngokufanelekileyo, eziya kuthi zinxulumane nohlengahlengiso kulo lonke olunye ulawulo lwamakhoboka kolo hlobo lolungelelwaniso. Okanye ungayenza ngendlela echaseneyo apho uhlengahlengisa izicwangciso zomlawuli oyintloko phambi kokuya kwimowudi ye-auto okanye yesandla, kuxhomekeke kuhlobo lwesikimu solawulo esilusebenzisayo nangaliphi na ixesha kwiinkqubo zethu.
Yintoni iCascade instrumentation?
Abalawuli badla ngokudityaniswa omnye komnye ngendlela yecascading. Oku kuthetha ukuba imveliso evela kumlawuli omnye ithunyelwa njengegalelo komnye, kunye nabalawuli bobabini abava imiba eyahlukeneyo yenkqubo efanayo.
Igama elithi "cascade" ngokuqhelekileyo libhekisela ekudibaniseni iingxangxasi ezininzi okanye imisinga kunye ukuze zihlangane ngaxa lithile ezantsi komsinga kwaye zenze ama-ripples amatsha phezu kwemidala; Ngale ndlela unokuyibona indlela eyakheka ngayo imilambo kunye nemifula ngokuhamba kwexesha kuba ithatha imijelo emincinci emininzi yongeza ukuqukuqela kwayo yonke indlela de ekugqibeleni kubekho umfutho owaneleyo wokuba bazibandakanye kwinto enkulu efana neLake Tahoe! Ngokufanayo, xa ezimbini (okanye ngaphezulu) zilawula iilophu ziphosa ngokuba nomqondiso obuyela emva-na-phambili phakathi kwazo ezihlala zihlengahlengisa iiparamitha.
Yintoni ulawulo lobushushu lweCascade?
Ulawulo lwe-Cascade kulawulo lobushushu lubandakanya iilophu ezimbini ezidityanisiweyo. I-loop yokuqala inika indawo emiselweyo yokufudumeza okulawulwayo kwe-PID, eyenzelwe ukuphendula kangcono kuneenzuzo zomgca kunye nokuphazamiseka kwindlela yokufudumala kunye nexesha lokuphendula eliphuculweyo.
