项目摘要

In general, when a novel rail way system is proposed, the ride-quality seems to be handled as secondary important issue. In addition, common discussion on ride-quality tend to be mainly devoted to how to choose springs and dampers.However recently active suspension systems begin to be payd attention to the industrial world. Such system to get high ride-quality positively are very interesting for researchers because they are able to show their skills sufficiently in control techniques.In this research, improvements in ride-quality of a maglev vehicle were aimed. Additionally robustness for maglev vehicle is supposed to be lightweight and springy is also aimed. Therefore some measures to meet them must be taken. To get both the high ride-quarity and the robust stabity in the lightweight and springy vehicle, H* robust theory was addopted in this research.The research process is as follows.1 : A maglev system was modelled for its nominal variables.2 : A weighting function to get the high ride-quality in the system was determined.3 : Another weighting function to get the robust stability corresponding to the modelling errors such as variation of the vehicle-weight and neglected high freq. oscillation modes of the springy cabin was determined.4 : An H* robust compensator was designed based on these weighting functions.5 : Both the high ride-quality and the robust stability in the system were comfirmed by digital simulations.6 : A simple experimental apparatus which is small but is imitative of a kind of actiral maglev vehicle was well-controlled by the above mentioned compensator with pneumatic actuators.Finally, I would like to report that some technical papers on this research were published.

总的来说，当提出一种新型的铁路方式系统时，乘车质量似乎是次要的重要问题。此外，关于乘车质量的普遍讨论往往主要致力于如何选择弹簧和阻尼器。但是，最近有活跃的悬挂系统开始引起人们对工业世界的关注。对于研究人员而言，这种积极效果的系统非常有趣，因为他们能够充分展示自己的控制技术。另外，磁磁车辆的鲁棒性应该是轻量级，并且还针对弹簧。因此，必须采取一些符合他们的措施。为了获得轻巧且弹性车的高骑行质量和稳健的稳定性，在这项研究中增加了H*稳健的理论。研究过程如下。1：一个以标称变量为名的磁磁系统。2：加权功能以确定系统的高度骑行功能，以确定较高的骑行功能。被忽视的高频。确定了弹簧客舱的振荡模式。报道了有关这项研究的一些技术论文。
