軽量磁気浮上車両の乗り心地改善とロバスト安定性の研究 A Study of Improvement in the Ride-Quality for a Light Weight MAGLEV Vehicle and the Robust Stability
Magnetically-levitated (MAGLEV) railway has been studied intensively in many countries for the purpose of its large scaled realization and in fact some plans have already also started in Japan.<br>In case of large scaled realization, a problem of how to reduce energy consumption must be discussed. To solve this problem a light weight vehicle is also used for a MAGLEV vehicle as well as convensional ones. Such a vehicle is flexible, which sometimes induces deterioration of ride-quality. Therefore to obtain high ridequality, active suspensions are applied to the vehicle. In this paper, we apply an H∞ control method to a system-model of the light weight vehicle including oscillation modes by adopting a suitable weighting function to be effective for a special frequency band at which high ride-quality is required.<br>In adition we pursue robust stability for both mass-variation by passengers' in and out and a modeling error by the neglect of the 3rd order oscillation mode and over.<br>At last the effect of our method proposed here is comfirmed by PSD (power spectral density) of the vehicle's acceration.
