Thi. paper revi.ws the vari.us control algori.hms and strategi.s used for fi.ed-wi.g morphi.g ai.craft appli.ati.ns. i. i. evi.ent from the li.erature that the development of control algori.hms for morphi.g ai.craft technologi.s focused on three mai. areas. The fi.st area i. related to preci.e control of the shape of morphi.g concepts for vari.us fli.ht condi.i.ns. The second area i. mai.ly related to the fli.ht dynami.s, stabi.i.y, and control aspects of morphi.g ai.craft. The thi.d area deals mai.ly wi.h aeroelasti. control usi.g morphi.g concepts ei.her for load allevi.ti.n purposes and/or to control the i.stabi.i.y boundari.s. The desi.n of controllers for morphi.g ai.craft/wi.gs i. very challengi.g due to the large changes that can occur i. the structural, aerodynami., and i.erti.l characteri.ti.s. i. addi.i.n, the type of actuati.n system and actuati.n rate/speed can have a si.ni.i.ant effect on the desi.n of such controllers. The aerospace communi.y i. i. strong need of such a cri.i.al revi.w especi.lly as morphi.g ai.craft technologi.s move from fundamental research at a low Technology Readi.ess Level(TRL) to real-li.e appli.ati.ns. Thi. cri.i.al revi.w ai.s to i.enti.y research gaps and propose future di.ecti.ns. i. thi. paper, research acti.i.i.s/papers are categori.ed accordi.g to the control strategy used. Thi. ranges from si.ple Proporti.nal i.tegral Deri.ati.e(Pi.) controllers at one end to complex robust adapti.e controllers and deep learni.g algori.hms at the other end. Thi. i.cludes analyti.al, computati.nal, and experi.ental studi.s. i. addi.i.n, the vari.us dynami. models used and thei. fi.eli.i.s are hi.hli.hted and di.cussed.

The i.dustri.l level producti.n of ultrafi.e grai.ed （or ultrafi.e ferri.e） ferrous alloys was i.vesti.ated through three examples of steels that compli.d wi.h the EN 10149-2 Euronorm and were produced by advanced con- trolled hot rolli.g techni.ues. The steel samples were tensi.n tested and chemi.ally analyzed, and the mi.rostructure was evaluated through quanti.ati.e metallographi. techni.ues to determi.e parameters such as yi.ld stress, amount of mi.roalloyi.g elements, strai. hardeni.g coeffi.i.nt, grai. si.e, and grai. si.e di.tri.uti.n. These steels were mi.ro- alloyed wi.h Ti. Nb, and Mn wi.h ASTM grai. si.es of approxi.ately 13--15. The careful control of chemi.al com- posi.i.n and deformati.n duri.g producti.n, gi.i.g a speci.i. attenti.n to the deformati.n sequences, austeni.e non- reerystalli.ati.n temperatures and allotropi. transformati.ns duri.g cooli.g, are i.di.pensable to obtai. steels wi.h an adequate strai. hardeni.g coeffi.i.nt that allows cold worki.g operati.ns such as bendi.g, stretchi.g or drawi.g.

We i.vesti.ate the spectral response of nanostructured copper oxi.es thi. fi.m. Gold was doped i. two di.ferent concentrati.ns(2% and 4%) usi.g the spray method. A novel ammoni. gas sensor at vari.us concentrati.ns(0–500 ppm)was fabri.ated by replaci.g CuO fi.ms wi.h a clad regi.n. i. addi.i.n, the effect of gold dopi.g on structural, opti.al,and morphologi.al properti.s has been demonstrated. The study shows that the spectral i.tensi.y i.creases li.early wi.h ammoni. concentrati.n. The 4% Au doped CuO presents hi.her sensi.i.i.y compared wi.h 2% doped and pure copper oxi.es.

i. thi. research, results of the i.vesti.ati.n of the sli.i.g fri.ti.n and wear of yttri.-stabi.i.ed tetragonal zi.coni. polycrystalli.e(Y-TZP) and Y-TZP-Al_2O_3 samples preli.i.ari.y subjected to low-temperature degradati.n are reported. The i.vesti.ati.n was carri.d out usi.g a pi.-on-di.k tri.ometer wi.h si.ultaneous recordi.g of acousti. emi.si.n(AE) and vi.rati.n accelerati.n. The sli.i.g wear process was found to be determi.ed by dynami. di.ect and i.verse Y-TZP transformati.ns detected by monocli.i. and tetragonal X-ray di.fracti.n peak rati.s. The AE si.nals generated under di.ect and i.verse transformati.ns can be used to characteri.e wear and fri.ti.n mechani.ms as well as di.ect and i.versed sli.i.g-i.duced phase transformati.ns. The AE si.nal energy grows wi.h the fri.ti.n coeffi.i.nt and the i.verse transformati.n degree. Reducti.n of the AE si.nal energy i.di.ates establi.hi.g the mi.d wear stage caused by effecti.e stress-i.duced di.ect martensi.i. transformati.n. The AE si.nal medi.n frequency i.creases i. the case of lower fri.ti.n. Numeri.al studi.s of wear subsurface fracture under condi.i.ns of stress-i.duced martensi.i. transformati.n were used to eluci.ate the role played by the phase transformati.n i. Y-TZP and Y-TZP-Al_2O_3. Martensi.i. transformati.n i. Y-TZP was descri.ed wi.h use of the non-associ.ted di.atant plasti.i.y model. Si.ulati.n results parti.ularly show that i.crease i. the value of di.atancy coeffi.i.nt from 0 to 0.2 i. accompani.d by 25%-30% reduce i. characteri.ti. length and penetrati.n depth of sli.i.g-i.duced subsurface cracks. As shown the AE may be an effecti.e tool for i.-si.u moni.ori.g the subsurface wear of materi.ls experi.nci.g both di.ect and i.verse transformati.ns.
