Kwinkqubo yokulawula i-steam electro-hydraulic, iI-servo valveI-G771k201 idlala indima ebaluleke kakhulu, kwaye intsebenzo yayo inxulumene ngqo nokuchaneka kolawulo kunye nokuzinza kwale nkqubo iphela. Nangona kunjalo, i-bias bias dhenomenon ifana ne "Ghost", ehlala isongela ukusebenza kwesiqhelo kwi-valve ye-servo ye-encro-hyddrailic. Ke ngoko, ingabaluleka okukhulu kakhulu ukuba nokuqonda okunzulu kwe-Arois bift bift vanomenon ye-servo valve g771k2k2k2k2k2k01 kwaye inkosi ifumana iindlela ezichanekileyo kunye neendlela zokulinganisa.

I-1. Uhlalutyo lwe-Arois bift bift fanomenon ye-servo valve g771k2k2k2k2k2K

I-Zero ye-zero ye-servo valve g771k01, ngokulandelelana, kubhekiswa kwimeko apho igalelo okanye uxinzelelo aluna-zero xa kungekho signali yolawulo. I-Aroift ye-Heas Drift ibhekisa kutshintsho olungalawulekiyo lwexabiso le-zero bias ngokutshintsha kwexesha, ubushushu, uxinzelelo lwenkqubo kunye nezinye izinto.

Zininzi izinto ezibangela ukuba i-zero bias ikhwele. Ukusuka kwizinto zangaphakathi, ukunxiliswa kwezinto zangaphakathi ze-servo valve sisizathu esibalulekileyo. Umzekelo, emva kokusetyenziswa kwexesha elide, ukucaciswa okuthe kratya phakathi kwe-valve kunye ne-veveve ye-valve inokutshintsha, kukhokelela kutshintsho kwinani lokuvuza kukalwelo, nto leyo ebangela i-zero bias caas. Ukongeza, ukudinwa kokukhathazeka kwentwasahlobo akunakutyeshelwa. Ngexesha lolwandiso lwexesha elide kunye nenkqubo yokuphambana, ukungathobeki kwentwasahlobo kusenokutshintsha, kuchaphazele indawo yokuqala yeValve Core, ngaloo ndlela ibangela ukuba i-Deas Bift. Ngokwembono yezinto zangaphandle, utshintsho lobushushu lunefuthe elibonakalayo kwi-Deas Bift. Ukuguquguquka kweqondo lobushushu kuya kubangela i-coefficents eyandiswayo yezinto ezikwi-servo ye-servo, ebangela ukuba amalungu ayo atshintsha, ngaloo ndlela ebangela ukuba aguquke. Ukongeza, ukungazinzi koxinzelelo lwenkqubo kunokubangela ukukhwela i-zero. Ukugcuma koxinzelelo kuya kuvelisa amandla ongezelelweyo kwi-valve, ebangela ukuba iphambuke kwisikhundla sokuqala sero.

I-2. Indlela yokufunyanwa kwe-zero bias ye-bift ye-servo valve g771k01

(I) indlela yokuchonga

Indlela yokuchonga eyi-Otic yindlela esisiseko neqhelekile. Xa inkqubo ikwimeko ye-static, izixhobo zokuchonga zoqeqesho, ezinjengokuchaneka okukhuluizinzwa zoncedokwaye izinzwa ezihambayo, zisetyenziselwa ukulinganisa uxinzelelo lwemveliso kunye nokuhamba kwe-servo valve xa kungekho galelo lolawulo. Okokuqala, ngokuthembekileyo uqhagamshele kwi-servo ye-servo kwinkqubo yokufunyanwa ukuqinisekisa ukuba inkqubo ikwimeko yokuqala. Emva koko, bhala ingcinezelo kunye nedatha yokuhamba ematyalwe ngumbandela ngeli xesha, ezixabisekileyo zokuqala ze-zero bias. Phantsi kweemeko ezahlukeneyo zokusingqongileyo, ezinje ngamaqondo obushushu ahlukeneyo kunye nokufuma, ukulinganisa amaxesha amaninzi kwaye uthelekise idatha elinganayo. Ukuba kukho ukuguquguquka kwedatha, kwaye ubudlelwane obungaphezulu bugqitha kuluhlu lwemposiso, emva koko bunokumisela kwangaphambili ukuba i-valve ye-servo ine-bero bias ikhwele i-bero bias.

(Ii) Indlela yokuqasha

Indlela yokuchonga eguqukayo inokubonisa i-zero bias ye-bift ye-servo valve ngexesha lokusebenza okufanelekileyo. Ngexesha lokusebenza kwenkqubo, umqondiso wolawulo, ukuhamba kwemveliso kunye neeparamitha ze-servo ze-serve ziqokelelwa ngexesha lokwenyani kusetyenziswa inkqubo yokufumana idatha. Ngokuhlalutya le datha enamandla, qwalasela ukuba ikhutshiwe ingaba ikhutshiwe ihamba ngexabiso elisigxina xa uphawu lokulawula li-zero. Iindlela zokulungisa ezisayiniweyo ezinje ngohlalutyo lwe-spectrum zinokusetyenziselwa ukuhlalutya i-frequency kunye nokuxoka. Ukuba i-amit amcungx enkulu kwaye i-frequency ibonisa rhoqo okanye isitenxo, emva koko ibonisa ukuba i-vallu ye-serso inokuba ne-yero bias cas. Umzekelo, emva kokuba inkqubo iqhubekile kangangexesha elithile, kufumanisa ukuba ukuphuma kwemveliso kuguquguqukayo kangangexesha elithile xa uphawu lokulawula li-zero. Emva kokuhlalutya kunye nokukhupha ezinye izinto eziphazamisayo, kunokwenzeka ukuba i-zero bias ye-valvo ye-servo iqhubekile.

(Iii) Indlela yokuthambisa imodeli esekwe kwimodeli

Ngokuphuhliswa kwethiyori yolawulo lwanamhlanje kunye netekhnoloji yekhompyuter, iindlela zokuchonga imodeli ezisekwe kwimodeli zisetyenziswe ngokubanzi. Okokuqala, qaphela imodeli echanekileyo yemathematics ye-servo valve g771k2k20, ekufuneka ikwazi ukuchaza ngokuchanekileyo igalelo kunye neempawu ze-servo valve phantsi kweemeko ezahlukeneyo zomsebenzi. Emva koko, thelekisa eyona nto iqokelelweyo ye-serso eqokelelweyo kunye nedatha yokuphuma kunye nexabiso lemodeli. Ukuba ukuphambuka phakathi kwezi zinto zimbini zingaphezulu komda osetiweyo, oko kuthetha ukuba i-serso ye-serso inokuba ne-zero bias ye-zero. Umzekelo, sebenzisa imodeli yenethiwekhi ye-Neural kwimodeli yeempawu ze-servo valve, igalelo lexesha lokwenyani eliqokelelweyo kwimodeli yokuqikelela, kwaye igwebe i-Arois bias ngokuthelekisa umahluko phakathi kwexabiso eliqikelelweyo kunye nexabiso eliqikelelweyo. Le ndlela inobungqiqo kunye nobukrelekrele, kodwa zifuna ubungakanani bedatha yovavanyo yokuqeqesha imodeli ukuqinisekisa ukuthembeka kwemodeli.

3. Indlela yokulinganisa ye-zero bias drift ye-servo valve g771k2k2k2k2k2k2k2k2k

(I) Uhlengahlengiso lohlengahlengiso

Uhlengahlengiso lohlengahlengiso lomatshini yindlela ethe ngqo. Kwi-bias bias ebangelwa zizizathu zoomatshini njengendawo ye-valve yokugcina, ukulinganisa kunokwenziwa ngokuhlengahlengiswa kwesikhundla sokuqala se-valve. Okokuqala, vula iqokobhe elingaphandle le-servo kwaye ufumane indlela yohlengahlengiso lwe-valve. Emva koko, sebenzisa izixhobo zobungcali, njengokuchaneka kwe-screcdrivers, ukuhlengahlengisa indawo ye-valve kwindawo echaziweyo kunye ne-amplity. Ngexesha lenkqubo yohlengahlengiso, dibanisa indlela yokuchonga into yokubonisa ukulinganisa ixabiso le-zero bias ye-servo valve ngexesha lokwenyani de kube kwinqanaba le-Affied lifikelela kuluhlu oluchaziweyo. Emva kokuba uhlengahlengiso lugqityiwe, qinisekisa ukuba indlela yohlengahlengiso lwe-valve limiselwe ngokuqinileyo ukuthintela ukufuduswa ngexesha lokusebenza.

(Ii) Ulungelelaniso lweMbuyekezo yoMbane

Ukulinganiswa kweMbuyekezo yoMbane usebenzisa imiqondiso yombane ukuze ihlawule ifuthe le-zero bias drift. Ngokongeza isekethe yembuyekezo okanye isoftware ye-algorithm kwinkqubo yolawulo, uphawu lwemveliso ye-servo valve ilungisiwe ngexesha lokwenyani. Umzekelo, ngokubhekisele kwi-Hardware, isiphaluka sembuyekezo esekwe kwi-Amplifier yokuSebenza sinokuyilwa ukuvelisa uphawu lwembuyekezo malunga nexabiso le-zero bias, ecinyiwe kwi-stoble ye-serve ye-serve. Ngokwesoftware, ulawulo lwe-algorithms lunokusetyenziselwa ukulungisa ubungakanani bemali yembuyekezo ngokwenyani ye-zero yokwenyani yokufumana idatha yeI-servo valveizinzile ngakumbi.

(Iii) Ukutshintshwa kwamacandelo aphambili ukuze ufumane ulungelelwaniso

Ukuba ifunyenwe ngokutshintshwa ukuba i-bias bift ibangelwa ngumonakalo okanye ukwaluphala kwezinto ezithile eziphambili ngaphakathi kwi-valve ye-servo, emva koko ukutshintsha la macandelo yindlela efanelekileyo yokubhala. Umzekelo, ukuba intwasahlobo inesidima elandelekileyo, isiphumo se-bias ye-zero, emva koko intwasahlobo entsha kufuneka itshintshwe. Xa kutshintsha iinxalenye, qinisekisa ukuba iindawo ezikhethiweyo zezomgangatho onokuthenjwa kwaye zihambelana ngokupheleleyo nenkcazo yamacandelo eqobo. Emva kokuba kugqityiwe ukutshintshwa, ivalve ye-servo ihlolwe ngokupheleleyo kwaye iphinde iphinde iphinde iqiniseke ukuba i-tensogued ukuqinisekisa ukuba intsebenzo yayo ibuya kumanqanaba aqhelekileyo.

Ngokuthatha iindlela zokufumana izinto ezifanelekileyo, iingxaki ze-bias ze-biaft zinokufunyanwa ngexesha elifanelekileyo nelichanekileyo. Kwi-bias bias ebangelwa zizizathu ezahlukeneyo, ivalve ye-servo inokulungelelaniswa ngempumelelo ngokusebenzisa uhlengahlengiso lohlengahlengiso lolingano, kunye nokutshintsha kwenkqubo yokulawula i-turbine electro-hyddra-hyddrailic. Kuphela ngokwenza umsebenzi olungileyo ekufumaneni nasekufumaneni i-zero bias ye-bias ye-servo valve g771k0 ingaqinisekiswa kwangaphambili kwenkqubo yolawulo lwe-turbine ye-turbine ye-turbine electro-hydralic iqinisekisiwe, ibonelela ngesiqinisekiso esiqinileyo sozinzo.

Xa ujonga ixesha eliphezulu, elinokuthenjwa seenvor, ye-yoyek ngokungathandabuzekiyo kukhetho olufanele ukuthathela ingqalelo. Inkampani ithathe inxaxheba ekunikezeleni ngezixhobo zamandla amandla kubandakanya izixhobo ze-turbine, kwaye iphumelele iingxowa-mali ngokubanzi kwiimveliso zayo eziphezulu kunye neenkonzo.
