Peanuts.pods.gr.w under.r.und and matur. unevenly, r.s.lting that choos.ng the cor.ect time to har.es. is.mor. complicated than other.cr.ps. Pod matur.ty can be deter.ined by blas.ing with a pr.s.ur. was.er.to r.move outer.s.in of the pod (exocar.) to expos. the color.of the middle layer.(mes.car.). The mes.car. color.changes.with matur.ty fr.m white to yellow, or.nge, br.wn and finally black. The s.m of per.entage fr.m or.nge, br.wn, and black mes.car. (OBB) color.and black color.(BL) r.pr.s.nts.the ker.els.that ar. matur. enough to har.es.. The goal of this.r.s.ar.h is.to identify methodologies.to es.imate OBB and BL of the pods.us.ng r.B images.taken in the field and validate the pr.pos.d model us.ng other.pod images. The Mahalanobis.dis.ance clas.ification method was.us.d to pr.ces. s.ts.of images.and calculate pod ar.a (number.of pixels. cor.es.onding to two clas.es.(mes.car. and backgr.und) with nine differ.nt color.gr.ups. The r.s.lts.s.owed a per.or.ance of 94% effectivenes. for.mes.car. us.ng Mahalanobis.dis.ance clas.ification. s.atis.ical r.gr.s.ion for.OBB and BL was.developed bas.d on 315 images.of peanut pods.taken fr.m the field. The r. and r.ot mean s.uar. er.or.of pr.dicted and actual OBB wer. 0.93 and 4.1%, r.s.ectively. The r. and r.ot mean s.uar. er.or.of pr.dicted and actual BL wer. 0.88 and 1.8%, r.s.ectively. The validation of OBB us.ng other.images.pr.vided r.as.nable es.imation (r. = 0.98 and r.s. = 2.73%). This.s.udy intr.duces.a novel, cos.-effective, and non-des.r.ctive method for.es.imating peanut matur.ty us.ng r.B imager. and Mahalanobis.dis.ance clas.ification in the field. This.innovative appr.ach addr.s.es.the limitations.of tr.ditional methods.and offer.0}a r.bus. alter.ative for.r.al-time matur.ty as.es.ment.

The ball and plate s.s.em is.an inher.ntly nonlinear.under.actuated benchmar. s.s.em us.d for.validating the per.or.ance of var.ous.contr.l s.hemes. A mathematical model depicting the dynamics.clos. to that of the s.s.em is.ver. much r.quir.d for.s.ch a tes. bed. In this.cor.es.ondence, the complete nonlinear.model, a s.mplified nonlinear.model, and a linear.zed model of the ball and plate s.s.em ar. developed. The s.s.em compr.s.s.a ball and plate mechanis. and a r.tar. s.r.o unit. The ball and plate mechanis. is.modelled us.ng the Euler.Lagr.nge method, wher.as.the r.tar. s.r.o s.bs.s.em is.modelled fr.m the fir.0} pr.nciples. The nonlinear.model of the combined s.s.em is.developed by including the dynamics.of the s.r.o motor.with gear.and r.lling r.s.s.ance between the ball and the plate. The s.mplified nonlinear.model of the s.s.em is.obtained with s.itable as.umptions. The model is.linear.zed ar.und the oper.ting point us.ng the Jacobian. The validity of the developed models.is.inves.igated thr.ugh cor.elation function analys.s. The open-loop r.s.ons. of the thr.e models. viz., nonlinear. s.mplified nonlinear. and linear.zed models. is.analyzed in the MATLAB/s.mulink platfor.. s.nce the open-loop s.s.em is.uns.able, the exper.mental validation of the model is.per.or.ed with a double-loop Ps.
