This study deals with a novel type of semiactive damper, which is composed of a cylinder injected with Magnetic Rheological Fluid(M.R.F.) and an electromagnet with a nonlinear H^* controller.It is generally known that the viscosity of M.R.F.can be changed by the magnitude of a magnetic field. Therefore, this study aims at constructing such a semiactive damper system that makes good use of the property.In 1996, a theoretical model of the novel semiactive damper was proposed. Next, a designing method of the H nonlinear controller for this type of damper was shown because the semiactive damper system has strong nonlinearity. Some advantages of the proposed semiactive damper were confirmed only by digital simulations.In 1997, a semiactive damper injected with a certain kind of M.R.F.was made and its basic properties were measured. As the results, it was shown the vscosity of the M.R.F.has the dynamic range which is suitable for control. In addition, a proper nonlinear compensator for the M.R.F.semiactive damper was actually installed and some vibration experiments were carried in order to catch basic caracteristics.In 1998, the theoretical model for designing compensators was altered so as to fit more for the characteristics of the actual device refering the results of many vibration experiments. Finally, the superiority was certified by many vibration experiments and digital simulations.

研究了一种新型的半主动阻尼器，它由一个注入磁流变液（M.R.F.）以及具有非线性H^* 控制器的电磁铁。众所周知，磁流变液的粘度可以通过磁场的大小来改变。因此，本研究旨在建构一种能充分利用此特性的半主动阻尼器系统，并于1996年提出一种新型半主动阻尼器的理论模型。其次，针对半主动阻尼器系统的强非线性特性，给出了该阻尼器H非线性控制器的设计方法。1997年，研制了一种注入某种磁流变液的半主动阻尼器，并对其基本性能进行了测试。结果表明，磁流变液的粘度具有适宜控制的动态范围。另外，还为磁流变半主动阻尼器实际安装了合适的非线性补偿器，并进行了振动试验，以掌握其基本特性，根据大量的振动试验结果，于1998年修改了设计补偿器的理论模型，使之更符合实际装置的特性。最后通过大量的振动实验和数字仿真验证了该方法的优越性。
