Nonlinear Modeling and Parameter Estimation of the Magnetic Levitation System Considering the Dynamics of the Control System (Case with Approximating the Electric Circuit and Magnetic Circuit Independently )
Abstract:The magnetic levitation system has not only the strong nonlinearity in the magnetic force but also the delays in electric circuit and magnetic circuit. This paper investigates the modeling of the magnetically levitated body considering both of them. The dynamic coefficients of the electric circuit and magnetic circuit of control system are estimated independently by using the transfer function. The model and estimated parameter values are validated experimentally by comparing the resonance curves of numerical … Show more
