| Outline of Final Research Achievements |
Weight reduction of railway vehicles is necessary to achieve high-speed transportation and optimal comfort. The ride quality of railway vehicles depends on the vibration of the car bodies generated while in motion. In the present study, a feedback method for synthesizing control systems to improve the ride quality is discussed. Separating the overall vibration of railway vehicles into lateral and vertical vibration components, vibration suppression can be achieved for each component by constructing independent control subspaces. In particular, a control subspace that manages lateral vibrations can not only achieve vibration suppression but also optimally evaluate the control energy and the control performance simultaneously. To evaluate this approach, an algorithm that designs the controller is proposed, and its usefulness is verified experimentally.
