Abstract

A modular rotational vibration system designed to facilitate the study of active control of vibrating systems is discussed. The model error associated with four common types of identification problems has been studied. The general multiplicative uncertainty shape for a vibration system is small in low frequencies, large at high frequencies. The frequency-domain error function has sharp peaks near the frequency of each mode. The inability to identify a high-frequency mode causes an increase of uncertainties at all frequencies. Missing a low-frequency mode causes the uncertainties to be much larger at all frequencies than missing a high-frequency mode. Hysteresis causes a small increase of uncertainty at low frequencies, but its overall effect is relatively small.<>

振动主动控制实验系统的研制与建模

为了便于研究振动系统的主动控制，提出了一种模块化旋转振动系统。研究了与四种常见识别问题相关的模型误差。一般振动系统的乘性不确定形状在低频时较小，在高频时较大。频域误差函数在每个模态的频率附近有一个尖峰。无法识别高频模式会导致所有频率的不确定性增加。缺少低频模态会导致在所有频率上的不确定性比缺少高频模态大得多。在低频时，迟滞会导致不确定性的小幅增加，但其总体影响相对较小。
