Abstract
System identification results of a magnetic suspension and balance system (MSBS) are presented in this study. A model to describe the system behaviors is a linearized equation of motion of the MSBS. Conventionally, unsteady aerodynamic forces have been estimated using the equation of motion and individually measured model parameters, however, it has not been confirmed the validity of the model in detail. In the study, the model parameters are identified from experimental data, and it is confirmed the linearized equation of motion with the identified parameters is valid for simulation of the model behavior and measurement of unsteady aerodynamic forces.
