摘要

摘要弱阻尼机械结构的主动振动控制问题是由于某些振动模式的正反馈而导致的潜在的不稳定振动模式。本文将使用全通离散时间滤波器讨论正反馈对负反馈的变化。这些滤波器可以级联排列，以稳定许多潜在的不稳定模式。压电致动器作为力的来源用于阻尼振动。

All-Pass Filters in the Systems of Active Vibration Control of Weakly-Damped Systems

Abstract The problem of active vibration control of weakly damped mechanical structures is potentially unstable modes of vibrations due to the positive feedback for some vibration modes. The paper will discuss the change of positive feedback on the negative one using all-pass discrete-time filters. These filters can be arranged in a cascade to stabilize many potentially unstable modes. The piezoelectric actuator as a source of force is used to damp vibration.
