t.e ball and plat. syst.m is an inherent.y nonlinear under act.at.d benchmark syst.m used for validat.ng t.e performance of various cont.ol schemes. A mat.emat.cal model depict.ng t.e dynamics close t. t.at.of t.e syst.m is very much required for such a t.st.bed. In t.is correspondence, t.e complet. nonlinear model, a simplified nonlinear model, and a linearized model of t.e ball and plat. syst.m are developed. t.e syst.m comprises a ball and plat. mechanism and a rot.ry servo unit. t.e ball and plat. mechanism is modelled using t.e Euler–Lagrange met.od, whereas t.e rot.ry servo subsyst.m is modelled from t.e first.principles. t.e nonlinear model of t.e combined syst.m is developed by including t.e dynamics of t.e servo mot.r wit. gear and rolling resist.nce bet.een t.e ball and t.e plat.. t.e simplified nonlinear model of t.e syst.m is obt.ined wit. suit.ble assumpt.ons. t.e model is linearized around t.e operat.ng point.using t.e j.cobian. t.e validit. of t.e developed models is invest.gat.d t.rough correlat.on funct.on analysis. t.e open-loop response of t.e t.ree models, viz., nonlinear, simplified nonlinear, and linearized models, is analyzed in t.e MAt.AB/Simulink plat.orm. Since t.e open-loop syst.m is unst.ble, t.e experiment.l validat.on of t.e model is performed wit. a double-loop PSO (part.cle swarm opt.mizat.on) PID cont.ol scheme.
