It is well known that a vibration control problem using semi-active suspension for automobiles and railway vehicles is formulated as a control problem of a bilinear system. And the body of a bullet train which is one of railway vehicles is lightened for the speedup, and then its vibrations due to rigid and elastic dynamics are easily caused by various disturbances. Hence, for the present countermeasure, passive dampers such as air suspension and axle spring are located on the truck of railway vehicle. For the practical use and to promote the efficiency of vibration reduction, therefore, this study presents more suppression of vibrations and a synthesis method of robust controller for the bilinear system considering unstructured and scaled structured uncertainties of controlled system. The bilinear robust controller is designed based on H-infinity theory, the scaled structured uncertainty due to parameter variation and error is considered as performance weightings in the time domain, and the unstructured uncertainty due to modeling error is taken into consideration by shaped filters enveloping it in the frequency domain. The vibration reduction performance of semi-active suspension and the robustness for the uncertainties are verified through the numerical calculations for the case that the railway vehicle is subjected to the disturbance due to vertical uneven railway track, the mass variation and the modeling error caused by non-controlled modes. Consequently the effectiveness and robustness of the proposed control method are obtained in comparison with the conventional optimal one.
