(1) Studies of Nonlinear Control Magnetic SuspensionA magnetic suspension system by means of nonlinear control was designed and constructed. The compliance of the magnetic suspension system was measured. More high compliance system was obtained comparing with a linear control system. In an integral type control system, steady state characteristics is good.However, there are difficulty to insure the atability.Other several nonlinear control methods were designed and compared.(2) Study of Single-Axis Repulsive Type Magnetic BearingA magnetic bearing system whose radial motions are restrained by permanent magnets and axial motion is controlled by an electromagnent was designed and constructed.High compliance magnetic bearing system was obtained. However, a whirling motion is occured. It is desirable to study to control the whirling motion by use of a few electromagnets.(3) General Techniques for Magnetic SuspensionIn order to assist the above studies, the following items were studied. ・Investigation of techiniques of magnetic suspension. ・Application of Hinfinity control theory. ・Experiments for the practical use of magnetic bearings

(1)非线性控制磁悬浮的研究设计并构建了采用非线性控制的磁悬浮系统，并测量了磁悬浮系统的柔度，与线性控制系统相比，获得了更高的柔度。系统稳态特性良好，但稳定性难以保证。设计并比较了其他几种非线性控制方法。(2)单轴斥力型磁力轴承研究径向运动为设计并构造了永磁体约束和电磁体控制的轴向运动。获得了高柔量磁力轴承系统，但是，需要研究使用少量电磁体来控制涡动运动。 (3) 磁悬浮的一般技术为了协助上述研究，进行了以下项目的研究 ・磁悬浮技术的研究 ・Hinfinity 控制理论的应用。・磁力轴承的实用化实验
