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.

一般来说，当提出一种新颖的铁路系统时，乘坐质量似乎被视为次要的重要问题。此外，关于乘坐质量的常见讨论往往主要集中在如何选择弹簧和阻尼器。然而，最近主动悬架系统开始受到工业界的关注。这种能够积极获得高乘坐质量的系统对于研究人员来说非常有趣，因为他们能够在控制技术方面充分展示自己的技能。在这项研究中，目标是提高磁悬浮车辆的乘坐质量。此外，磁悬浮车辆的坚固性还应该是轻量化和有弹性的。因此必须采取一些措施来满足这些要求。为了使轻质、有弹性的车辆同时获得高乘坐质量和鲁棒稳定性，本研究采用了H*鲁棒理论。研究过程如下。1：对磁悬浮系统的标称变量进行建模。2：确定了系统中获得高乘坐质量的加权函数。3：另一个加权函数，用于获得与建模误差（例如车辆重量的变化和忽略的高频）相对应的鲁棒稳定性。确定了弹性舱的振动模式。4：基于这些权重函数设计了 H* 鲁棒补偿器。5：通过数字仿真证实了系统的高乘坐质量和鲁棒稳定性。6：一个简单的实验通过上述带有气动执行器的补偿器，可以很好地控制小型但模仿一种实际磁浮车辆的装置。最后，我想报告一下，关于这项研究的一些技术论文已经发表。
