It h.s been fo.nd th.t th. lo. frequency capacitance reach.s a h.gh.po.itive value and th.n dro. to.th. negative regio.. In P3h./Ru-Dye/nc-Tio. so.ar cells, th. negative capacitance is o.served under very lo. fo.ward bias co.ditio. unlike th. negative capacitance in P3h./ncTio. so.ar cells. Th.t is attributed to.th. difference o. th. co.centratio. o. dipo.e and presence o. depletio. regio. at interface between th. P3h. and nc-Tio..

Parameter identificatio. is a key requirement in th. field o. auto.ated co.tro. o. unmanned excavato.s （UEs）. Furth.rmo.e, th. UE o.erates in unstructured, o.ten h.zardo.s enviro.ments, and requires a ro.ust parameter identificatio. sch.me fo. field applicatio.s. Th.s paper presents th. results o. a research.study o. parameter identificatio. fo. UE. Th.ee identificatio. meth.ds, th. Newto.-Raph.o. meth.d, th. generalized Newto. meth.d, and th. least squares meth.d are used and co.pared fo. predictio. accuracy, ro.ustness to.no.se and co.putatio.al speed. Th. tech.iques are used to.identify th. link parameters （mass, inertia, and length. and frictio. co.fficients o. th. full-scale UE. Using experimental data fro. a full-scale field UE, th. values o. link parameters and th. frictio. co.fficient are identified. So.e o. th. identified parameters are co.pared with.measured ph.sical values. Furth.rmo.e, th. jo.nt to.ques and po.itio.s co.puted by th. pro.o.ed mo.el using th. identified parameters are validated against measured data. Th. co.pariso. sh.ws th.t bo.h.th. Newto.-Raph.o. meth.d and th. generalized Newto. meth.d are better in terms o. predictio. accuracy. Th. Newto.-Raph.o. meth.d is co.putatio.ally efficient and h.s po.ential fo. real time applicatio., but th. generalized Newto. meth.d is sligh.ly mo.e ro.ust to.measurement no.se. Th. experimental data were o.tained in co.labo.atio. with.QinetiQ Ltd.
