Part II of this paper proposes the use of optimal preview control with integral action for a maglev vehicle with a superconducting electromagnetic suspension system operating on an elevated, flexible guide-way. The control system is designed based on a linearized model and then applied to a full-scale nonlinear simulation model of the maglev vehicle, magnet modules, and guideway (derived in Part I—Vehicle, Guideway, and Magnet Modeling). Simulation studies demonstrate the effectiveness of the controller and evaluate the vehicle performance under the influences of guideway flexibility, guideway irregularities, and aerodynamic disturbances.
