Mathematical modelling of ball and plate system with exper.mental and cor.elation function-based model validation

引用

Contr.l Theor. and Technology 2024年第2期22卷 326-341页

作者： T.r.Dil Kumar.S.J.Mija Depar.ment of Electr.cal Engineer.ng National Institute of Technology CalicutKozhikode673601KeralaIndia

The ball and plate system is an inher.ntly nonlinear.under.actuated benchmar. system used for.validating the per.or.ance of var.ous contr.l schemes. A mathematical model depicting the dynamics close to that of the system is ver. much r.quir.d for.such a test bed. In this cor.espondence, the complete nonlinear.model, a simplified nonlinear.model, and a linear.zed model of the ball and plate system ar. developed. The system compr.ses a ball and plate mechanism and a r.tar. ser.o unit. The ball and plate mechanism is modelled using the Euler.Lagr.nge method, wher.as the r.tar. ser.o subsystem is modelled fr.m the fir.t pr.nciples. The nonlinear.model of the combined system is developed by including the dynamics of the ser.o motor.with gear.and r.lling r.sistance between the ball and the plate. The simplified nonlinear.model of the system is obtained with suitable assumptions. The model is linear.zed ar.und the oper.ting point using the Jacobian. The validity of the developed models is investigated thr.ugh cor.elation function analysis. The open-loop r.sponse of the thr.e models, viz., nonlinear. simplified nonlinear. and linear.zed models, is analyzed in the MATLAB/Simulink platfor.. Since the open-loop system is unstable, the exper.mental validation of the model is per.or.ed with a double-loop PSO (par.icle swar. optimization) PID contr.l scheme.

Inter.ational Jour.al of Otolar.ngology and Head & Neck Sur.er. 2024年第4期13卷 275-284页

作者： Alexandr. McMillan Sameer.A. Alvi Zaid Al-Qur.yshi Zachar. Fleishacker.Nitin A. Pagedar.Mar.sa r.

North Shore University Health System Evanston IL USA Pr.tzker.School of Medicine The University of Chicago Chicago IL USA Holden Compr.hensive Cancer.Center University of Iowa Iowa City IA USA

Objectives: The anter.later.l thigh (ALT) flap is often consider.d the wor.hor.e in soft tissue r.constr.ction of head and neck defects secondar. to tr.uma, infection, or.tumor.r.section. Despite its many advantages, ALT flaps have been cr.ticized due to var.ability in vasculatur., which may r.sult in inadequate or.non-existent per.or.tor.. This r.tr.spective study aims to investigate the utility and validity of positr.n emission tomogr.phy (PET) scan to identify the location and char.cter.stics of per.or.tor. to the ALT flap. Methods: We per.or.ed a 10-year.r.tr.spective r.view of ALT flaps at our.institution to identify patients with pr.oper.tive PET scans available for.analysis. Thr.e r.viewer. (attending physician, fellow, and r.sident) wer. asked to identify the number. location, and char.cter.stics (myocutaneous ver.us septocutaneous) of ALT per.or.tor. on imaging, and r.viewer.agr.ement was assessed. r.sults wer. then compar.d to available oper.tive data. r.sults: One hundr.d twenty-one patients wer. identified who under.ent ALT fr.e flap sur.er.. Thir.y-eight pr.oper.tive PET scans wer. identified for.r.view. At least one per.or.tor.was identified in 92.1% of scans. Agr.ement per.entages r.gar.ing the number.of per.or.tor. r.nged fr.m 53% - 61% wher.as agr.ement r.gar.ing the location of a single per.or.tor.r.nged fr.m 79% - 90%. However. r.viewer. did not agr.e r.gar.ing the type of per.or.tor. with agr.ement r.nging fr.m 34% - 53%. Poor.agr.ement was obser.ed when compar.d to intr.oper.tive data, with the number.of per.or.tor. r.nging fr.m 26% - 34% and the type of per.or.tor.11% - 24%. These findings ar. likely due to insufficient data available in oper.tive r.por.s. Conclusion: Although initial studies suggest that PET scan shows pr.mising evidence to suppor. the capacity to pr.oper.tively identify ALT per.or.tor., futur. pr.spective studies ar. war.anted to fully validate these findings.
