最近提出了基于反射波抑制的谐振系统振动抑制。该方法通过波动方程对谐振系统进行建模，以考虑高阶振动，并通过消除谐振系统的反射波来实现振动抑制。然而，当存在输入和输出时间延迟时，不可能实现这种方法，因为它需要实现时间延迟的倒数。本文提出了一种新的振动抑制方案，用于通过使用改进的反射波抑制来抑制受时间延迟影响的谐振系统。即使存在时间延迟，只要满足此类延迟值的某些条件，也可以应用所提出的反射波抑制。仿真和实验结果证实了该方法的有效性。
The vibration suppression on a resonant system, based on the reflected wave rejection, has been recently proposed. In the method, the resonant system is modeled through a wave equation, in order to consider high order vibrations and vibration suppression is achieved by eliminating a reflected wave from the resonant system. However, it is impossible to implement such method when there are input and output time delays, because it would require the implementation of the inverse of a time delay. This paper proposes a new vibration suppression scheme for a resonant systems, affected by time delay, by using a modified reflected wave rejection. The proposed reflected wave rejection can be applied even in presence of time delays, as long as some conditions on the value of such delays are satisfied. The validity of the proposed method is confirmed by simulations and experimental results.
