This paper proposes the concept of sky-hook spring applying to an electromagnetic suspension with zero-power control. The authors combined the concept of zero-power control with sky-hook spring and damper to make the floated mass in the electromagnetic suspension system followed the rail with zero power in low frequency, with excellent performance of vibration isolation in high frequency. In experiments, an accelerometer and a high-pass-filter is used to realize the sky-hook spring and damper for isolating vibration in high frequency. The measured gap with a low-pass-filter is used to stabilize the electromagnetic suspension system under supporting the floated mass by a permanent magnet. Experimental results with current or voltage control of the electromagnet verified the capabilities of the control methods proposed in this paper.
