摘要: 通过对磁悬浮飞轮陀螺力学进行研究,并分析电磁力对转子章动、进动特性的影响,将磁轴承电磁力对飞轮转子的作用分成四种基本支承成分,分别讨论它们对转子章动与进动稳定性的不同影响。控制器可通过调整四种基本成分在总的电磁力中的比重,改变转子章动、进动的阻尼特性,实现转子的高速稳定运行。基于这些分析,总结出磁悬浮飞轮控制器设计的基本原则。该原则为高速下磁悬浮飞轮转子系统控制器的设计指明方向。

Abstract: Through the study of gyroscopic dynamics of a flywheel rotor system supported by active magnetic bearings, and the analysis of the influences of magnetic forces to the nu-tation and the precession of the rotor, the effects of the magnetic forces to the rotor are divided into four basic supporting com-ponents. Their different influences to the stability of the nuta-tion and the precession are discussed respectively. The propor-tion of the four components can be adjusted by a controller to change the damping characters of the nutation and the preces-sion, and achieve a high speed operation. Based on the study, the principles of controller designs for flywheel systems sup-ported by active magnetic bearings are summarized, and they provide a direction for designing effective controllers for the systems at high rotation speeds.
