In this research, the phenomena such as nonlinear frictions, dead-zone and time-delay in the ball and beam mechanism's mathematical model is investigated. The following procedures are taken to construct a credible mathematical model of the system for this purpose. Firstly, the ball and beam mechanism's mathematical model, which includes different probable physically meaningful nonlinearities, is simulated using MATLAB\Simulink. Then, the Particle Swarm Optimization (PSO) algorithm is coded to determine the exact nonlinear model of a ball and beam system using the experimental data. Third, the accuracy of the results obtained from the PSO algorithm is tested using the hypothesis test and the confidence interval test. According to the statistical tests, the PSO algorithm is highly accurate in determining the parameters of the actual model of the system. © 2023 IEEE.eninfo:eu-repo/semantics/closedAccessNonlinear systemsStatistical testsBall and beamBeam mechanismDead timeDead zonesIn-laboratory experimentsMechanism mathematical modelNonlinear frictionNonlinear model identificationParticle swarm optimization algorithmTime-delaysParticle swarm optimization (PSO)Conference Object10.1109/CoDIT58514.2023.102841052-s2.0-85177422951
