Kwinkalo yomlinganiselo we-inertial measurement (IMUs),iigyroscopes ezine-axis ezintathuzivelele njengamacandelo abalulekileyo, ukubonelela ngedatha ebalulekileyo yokulawula isimo sengqondo kwizicelo ezivela kwi-aerospace ukuya kwiinkqubo zeemoto. Ukuqonda imigaqo yozinzo ye-gyroscope ye-axis emithathu ibalulekile ekuphuculeni ukusebenza kwayo kunye nokuqinisekisa ukusebenza okuthembekileyo kwiindawo eziguquguqukayo.
## Umgaqo wokusebenza we-gyroscope ene-axis ezintathu
Iigyroscopes ezine-axis ezintathusebenza ngokulinganisa isantya se-angular malunga nee-asi ezintathu ezizimeleyo (X, Y, kunye no-Z). Xa iphantsi kokujikeleza kwangaphandle, i-gyroscope ivelisa i-angular velocity of rotation, ebaluleke kakhulu ekunqumeni ukuqhelaniswa kwesixhobo. Isakhiwo sangaphakathi se-gyroscope ye-axis emithathu ngokuqhelekileyo ibandakanya ukuchasana kwangaphakathi kwe-gyroscope, i-tachometer enamandla kunye ne-loop yokulawula. Ngokudibeneyo, la macandelo aququzelela ukufunyanwa kunye nolawulo lokuma kwesixhobo.
Ukumelana kwangaphakathi kwe-gyroscope kunceda ukugcina uzinzo ngokuxhathisa utshintsho kwintshukumo, ngelixa i-tachometer enamandla ilinganisa izinga lokujikeleza. I-loop yolawulo isebenza le datha, ivumela uhlengahlengiso lwexesha langempela ukugcina ulwalathiso olufunwayo. Ukusebenzisana okunzima phakathi kwamacandelo kuqinisekisa ukuba i-gyroscope inokulandelela ngokuchanekileyo utshintsho kwindawo kunye nokuqhelaniswa, okubaluleke kakhulu kwizicelo ezifuna ukuhamba ngokuchanekileyo kunye nokulawula.
## Umthombo ozinzileyo
Ukuzinza kwe-gyroscope ye-axis emithathu ikakhulu ivela kwimithombo emibini: ukuzinza komatshini kunye nokuzinza kwesiphaluka.
### Ukuzinza koomatshini
Ukuzinza komatshini kubalulekile ekusebenzeni okuchanekileyo kwe-gyroscope ye-axis emithathu. Isixhobo kufuneka sibonise ukuzinza okuphezulu komatshini ukunciphisa imiphumo ye-vibration kunye nokuphazamiseka kwangaphandle. Ukungcangcazela koomatshini kunokwazisa iimpazamo zomlinganiselo wesantya esise-angular, okukhokelela kumiselo lwesimo sengqondo esingachanekanga. Ukuthomalalisa le miba, abavelisi bahlala besebenzisa izixhobo ezirhabaxa kunye neendlela zokuyila ukomeleza ukuxhathisa kwegyroscope ukothuka koomatshini kunye nokungcangcazela.
Ukongezelela, ukulungiswa kunye nokufakwa kwe-gyroscope nayo idlala indima ebalulekileyo ekuzinzeni kwayo komatshini. Ukulungelelaniswa ngokuchanekileyo kunye nokunyuka okukhuselekileyo kunciphisa ngakumbi umngcipheko wokuphazamiseka kwamandla angaphandle, ukuqinisekisa ukusebenza kakuhle kwe-gyroscope phantsi kweemeko ezahlukeneyo zokusebenza.
### Uzinzo lwesekethe
Okubaluleke ngokulinganayo ukuzinza kwesiphaluka se-gyroscope ye-axis emithathu. Iisekethe ezibandakanyekayo ekusebenzeni kwesignali, ezifana neesekethe zokwandisa izibonakaliso ze-gyroscope kunye neesekethe zokucoca, kufuneka zibonise ukuzinza okuphezulu ukuqinisekisa ukuhanjiswa ngokuchanekileyo kwedatha. Ezi zijikelezo zenzelwe ukugatya ukuphazamiseka, ukukhulisa umqondiso, kunye nokwenza i-high-pass kunye ne-low-pass filtering, eyona nto ibalulekileyo ekugcineni ukunyaniseka komqondiso we-angular velocity.
Ukuzinza kwesekethe kubaluleke kakhulu kuba naluphi na uguquko okanye ingxolo kwisignali inokubangela ukufundwa kobuxoki, okuchaphazela kakubi ukusebenza kwenkqubo yokulawula. Ke ngoko, iinjineli zijolise ekuyileni iisekethe ezinokumelana nokutshintsha kwendalo kunye nokugcina ukusebenza okungaguqukiyo ngexesha.
## Ukusetyenziswa kwegyroscope ene-axis ezintathu
Iigyroscopes ezine-axis ezintathu zisetyenziswa ngokubanzi kwiinkalo ezahlukeneyo. Kwi-aviation, zibalulekile ekufezekiseni ulawulo oluzinzileyo lwesihloko kunye nesimo sengqondo, ukuvumela abaqhubi ukuba bahambe ngokukhuselekileyo nangokufanelekileyo. Kushishino lweemoto, ezi gyroscopes zisetyenziswa kwiinkqubo zoncedo lwabaqhubi (ADAS) ukuqinisa uzinzo kunye nolawulo lwezithuthi.
Ukongeza, kuhambo lwaselwandle, ii-gyroscopes ezine-axis ezintathu zisetyenziselwa ukulinganisa nokulawula isimo sengqondo esiguquguqukayo seenqanawa kunye neenqanawa ezintywila emanzini ukuze kuqinisekiswe ukuhamba okukhuselekileyo nokuchanekileyo kwiimeko ezinzima. Ukukwazi kwabo ukubonelela ngedatha yesikhokelo yexesha lokwenyani kubenza babaluleke kakhulu kwiinkqubo zokukhangela zanamhlanje.
## Isishwankathelo
Iigyroscopes ezine-axis ezintathuzisisiseko setekhnoloji yokulinganisa i-inertial, kwaye uzinzo kunye nokuchaneka kwazo kubalulekile ekulawuleni isimo sengqondo esisebenzayo. Ngokuqonda imigaqo yozinzo koomatshini kunye nesekethe, iinjineli zinokuyila iigyroscopes ezithembeke ngakumbi ukuhlangabezana neemfuno zezicelo ezahlukeneyo. Njengoko itekhnoloji iqhubeka nokuvela, indima yee-gyroscopes ezine-axis ezintathu kwii-IMUs iya kubaluleka ngakumbi, ivula indlela yenkqubela phambili yokuhamba, iirobhothi kunye namanye amacandelo.
