Abstract

Vibration suppression characteristics of an active magnetic suspension system are investigated. The vibration force compensation results from a linear oscillatory actuator (LOA) using feedback control from system measurements. The feedback terms are related to relative suspension deflection, relative suspension velocity, absolute mass acceleration and absolute mass velocity. By proper feedback the measured signals to the actuator controller, the damping effect of the proposed active suspension can be accomplished for better performance with some parameter adjustments
