项目摘要
There are some special phenomena in the high temperature superconducting levitation system as compared to the usual magnetic levitation system. This research discusses the method of modeling, control, stable levitation system and their application to the magnetic bearings and motors with consideration of the phenomena. The obtained results are as follews :(1) Expressions for obtaining the nonlinear restoring force was presented.(2) A method of modeling of the levitation force was derived.(3) A method of vibration control of the levitated body was presented which involves the feedback control with frequency weight with consideration of the nonlinear phenomena.(4) A new levitation system of the rotating shaft has been presented in which one superconductor supports one end of the shaft, but the other end is supported by a couple of permanent magnets. The levitation is stable without control in the system.(5) The active control method for controlling vibrations of the shaft was discussed. A combination method of cross feedback and optimal PD control was presented.(6) The method has enough effects for controlling shaft vibrations.(7) A non-contact superconducting levitation pulse motor was presented.
高温超导悬浮系统与常规磁悬浮系统相比,存在一些特殊现象。本研究针对这一现象,探讨了磁悬浮系统的建模、控制、稳定悬浮的方法及其在磁悬浮轴承和电机中的应用。(1)给出了求解非线性恢复力的表达式。(2)推导了悬浮力的建模方法。(3)针对悬浮体的非线性现象,提出了一种频率加权反馈控制的悬浮体振动控制方法。(4)提出了一种新型的转轴悬浮系统,其中超导体支撑转轴的一端,而另一端由一对永磁体支撑。悬浮是稳定的,在系统中没有控制。(5)探讨了主动控制方法对轴系振动的控制。提出了一种交叉反馈与最优PD控制相结合的方法。(6)该方法对控制轴振动有足够的效果。(7)介绍了一种非接触超导悬浮脉冲电机。
