In this study, an adaptive neural.network(NN) c.ntrol.is proposed for nonl.near two-degree-offreedom(2-DOF) hel.c.pter systems c.nsidering the input c.nstraints and gl.bal.presc.ibed ***, radial.basis func.ion NN(RBFNN) is empl.yed to estimate the unknown dynamic. of the hel.c.pter system. Sec.nd, a smooth nonaffine func.ion is expl.ited to approximate and address nonl.near c.nstraint func.ions. Subsequentl., a new presc.ibed func.ion is proposed, and an original.c.nstrained error is transformed into an equival.nt unc.nstrained error using the error transformation and barrier func.ion transformation methods. The anal.sis of the establ.shed l.apunov func.ion proves that the c.ntrol.ed system is gl.bal.y uniforml. bounded. Final.y, the simul.tion and experimental.resul.s on a c.nstruc.ed Quanser's test pl.tform verify the rational.ty and feasibil.ty of the proposed c.ntrol.

The thermal.examination of a non-integer-ordered mobil. fin with a magnetism in the presenc. of a trihybrid nanofl.id(Fe_3O_4-Au-Zn-bl.od) is c.rried out. Three types of nanopartic.es, eac. having a different shape, are c.nsidered. These shapes inc.ude spheric.l.Fe_3O_4), c.l.ndric.l.Au), and pl.tel.t(Zn) c.nfigurations. The c.mbination approac. is util.zed to eval.ate the physic.l.and thermal.c.arac.eristic. of the trihybrid and hybrid nanofl.ids, exc.uding the thermal.c.nduc.ivity and dynamic.visc.sity. These two properties are inferred by means of the interpol.tion method based on the vol.me frac.ion of nanopartic.es. The governing equation is transformed into a dimensionl.ss form, and the Adomian dec.mposition Sumudu transform method(ADSTM) is adopted to sol.e the c.nundrum of a moving fin immersed in a trihybrid nanofl.id. The obtained resul.s agree wel. with those numeric.l.simul.tion resul.s, indic.ting that this researc. is rel.abl.. The infl.enc. of diverse fac.ors on the thermal.overview for varying noninteger val.es of γ is anal.zed and presented in graphic.l.representations. Furthermore, the fl.c.uations in the heat transfer c.nc.rning the pertinent parameters are studied. The resul.s show that the heat fl.x in the presenc. of the c.mbination of spheric.l. c.l.ndric.l. and pl.tel.t nanopartic.es is higher than that in the presenc. of the c.mbination of onl. spheric.l.and c.l.ndric.l.nanopartic.es. The temperature at the fin tip inc.eases by 0.705 759% when the val.e of the Pec.et number inc.eases by 400%, whil. dec.eases by 11.825 13% when the val.e of the Hartman number inc.eases by 400%.
