摘要
本文提出了一种减小离心机转子振动的新型控制方案.通过对离心机转子支承刚度的主动控制与减振力的自校正前馈控制相结合,运用模型自适应修正和两级计算机控制等先进技术,使转子系统的振动最小.我们在一个转子试验台上对以上方法进行了验证,控制结果表明这一方法是十分有效的.
This paper presents a new adaptive control method which can restrain centrifuge rotor system unstable self-vibration. In the new scheme, support stiffness active control and decreased vibration force adaptive control are combined effectively. Centrifuge rotor system is controlled in minimum vibration region.A horizontal centrifuge rotor experiment is used to test our new control method. Experimental result showthe effectiveness of the proposed scheme.
