Paper Abstract

An electromagnetic levitation controller design considering vehicle-guideway interaction is presented. Even though to design a Maglev controller to make a vehicle steady suspension under guideway deflection is a key technology in Maglev vehicle system, the vehicle-guideway interaction effects haven't well explored and yet settled. The vehicle is approximated to a single moving reaction force and the primary and secondary suspension dynamics are applied to the model. The Bernoulli-Euler beam equation is used to model the dynamic deflection of guideway, which acts as a disturbance to the Maglev control system. Based on the model, a PID controller and a state feedback controller with a state observer are proposed. The feasibility of the controller is verified through the Simulink simulation.
