"Kuti muzindikire kuthekera konse kwa zowulukira zamagetsi izi, mufunika njira yowongolera yanzeru yomwe imawongolera kulimba kwawo komanso makamaka kulimba kwawo motsutsana ndi zolakwika zosiyanasiyana," akutero Soon-Jo Chung, Pulofesa wa Bren wa Control and Dynamical Systems ku Caltech ndi Senior Research Scientist ku JPL, yemwe Caltech amayang'anira NASA. "Tapanga njira yololera zolakwika yotereyi yofunikira pamakina odziyimira pawokha, ndipo imayambitsa lingaliro la masensa omwe amatha kuzindikira kulephera kulikonse pogwiritsa ntchito makina ophunzirira ndi njira zowongolera."
Ma Rotor Angapo Amatanthauza Zambiri Zomwe Zingatheke Zolephera
Mainjiniya akumanga ndege zamagetsi zosakanizidwazi zokhala ndi ma propeller angapo, kapena ma rotor, mwa zina kuti ziwonjezeke: Ngati rotor imodzi yalephera, ma mota ogwira ntchito okwanira amakhalabe kuti asayende. Komabe, kuti achepetse mphamvu yofunikira kupanga maulendo apandege pakati pa malo a m’tauni—titi, makilomita 10 kapena 20—chombocho chimafunikanso mapiko okhazikika. Kukhala ndi ma rotor ndi mapiko, komabe, kumapangitsa kuti pakhale zovuta zambiri mu ndege iliyonse. Ndipo izi zimasiya mainjiniya ndi funso la momwe angadziwire bwino ngati china chake chalakwika ndi gawo lililonse lagalimoto.
Akatswiri atha kuphatikiza masensa a rotor iliyonse, koma ngakhale sizingakhale zokwanira, akutero Chung. Mwachitsanzo, ndege yokhala ndi ma rotor asanu ndi anayi ingafunike masensa opitilira asanu ndi anayi, popeza rotor iliyonse ingafunike sensa imodzi kuti izindikire kulephera kwa rotor, inanso kuzindikira ngati injini yake ikusiya kuthamanga, ndi inanso kuchenjeza ngati vuto la waya. zimachitika. Chung anati: “M’kupita kwa nthawi mukhoza kukhala ndi masensa amene amagaŵidwa mochulukirachulukira, koma zimenezo zingakhale zodula, zovuta kuziwongolera, ndipo zingawonjezere kulemera kwa ndegeyo. Masensa omwewo amathanso kulephera.
Ndi NFFT, gulu la Chung lakonza njira ina, yatsopano. Kumanga patsogolo zoyesayesa zam'mbuyomu, gululi lapanga njira yophunzirira mozama yomwe siingathe kuyankha mphepo yamkuntho komanso kuzindikira, pouluka, pamene ndege yalephera kuyenda. Dongosololi limaphatikizapo neural network yomwe imaphunzitsidwa kale pa data yeniyeni ya ndege ndiyeno imaphunzira ndikusintha munthawi yeniyeni kutengera kuchuluka kwa magawo osinthika, kuphatikiza kuyerekezera momwe rotor iliyonse pa ndegeyo imagwirira ntchito nthawi iliyonse. nthawi.
"Izi sizifunikira masensa kapena zida zina zowonjezera kuti muzindikire zolakwika ndi kuzizindikira," akutero Chung. “Timangoona mmene ndegeyo imachitira—maganizo ake ndi mmene imayendera nthaŵi. Ngati ndegeyo ikuchoka pamalo omwe ikufunidwa kuchoka pamalo A kupita ku B, NFFT ikhoza kuona kuti chinachake chalakwika ndikugwiritsa ntchito zomwe ili nazo kuti zibwezere zolakwikazo. "
Ndipo kuwongolera kumachitika mwachangu kwambiri - pasanathe sekondi imodzi. "Kuwulutsa ndege, mutha kumva kusiyana komwe NFFT imapangitsa kuti ndegeyo isasunthike injini ikalephera," akutero Staff Scientist Matthew Anderson, wolemba papepala komanso woyendetsa ndege yemwe adathandizira pakuyesa ndege. "Kukonzanso nthawi yeniyeni kumapangitsa kuti zizimva ngati palibe chomwe chasintha, ngakhale injini yanu yasiya kugwira ntchito."
Kuyambitsa Virtual Sensors
Njira ya NFFT imadalira zizindikiro zowongolera nthawi yeniyeni ndi ma aligorivimu kuti azindikire komwe kulephera kuli, kotero Chung akuti imatha kupatsa mtundu uliwonse wagalimoto makamaka ma sensor aulere kuti azindikire zovuta. Gululi layesa makamaka njira yoyendetsera magalimoto omwe akupanga, kuphatikizapo Autonomous Flying Ambulance, galimoto yamagetsi yosakanizidwa yopangidwa kuti itenge anthu ovulala kapena odwala kuchipatala mwamsanga. Koma gulu la Chung layesa njira yofananira yowongolera zolakwika pamagalimoto apansi ndipo ali ndi mapulani oti agwiritse ntchito NFFT pamabwato.
