Abstract: In order to effectively eliminate the vibration of magnetically suspended flywheel(MSFW), the micro-vibration model of a special structure flywheel is built and analyzed. The vibration forces and torques are tested by using micro-vibration plate and data acquisition analysis hardware and software. By analyzing the characteristics of the forces and torques in time domain and frequency domain, their vibration characteristics diagram, i.e. waterfall diagram, shows that the main components of forces in X and Y radial direction are the same frequency components, multiplier frequency components and modal components. The vibration forces in X and Y radial directions are controlled via the open and closed loop adaptive notch filters, and the results are preferable.

Key words: magnetically suspended flywheel, magnetic bearing, active vibration control, adaptive notch filter
