Study on Control Method of Maglev Vehicle-Guideway Coupling System Based on Robust Control Theory

A new control method based on robust control theory was investigated to solve the stability problem of the maglev vehicle-guideway coupling system. The track beam's irregularity was analyzed and considered as disturbance in this system. The vibration requirement of the maglev vehicle was also considered when the controller was designed. The new designed control method was tested on a MATLAB/Simulink modal. The result shows that the new control method can make the vehicle-guideway coupling system stable and the robustness of the system was much better than the traditional control method based on optimal control theory. When there is disturbance in the system, the maximum overshoot is much smaller and with less oscillation.
