基于模态滤波器概念提出了对载荷识别模态模型法的原理性校正方案，构造了动载荷识别的离散模态滤波器模型。

Based on the conception of the discrete modal filter, a force identification model is proposed to emend the classical modal model method.

看待这个问题的一种方法是，系统模态只不过是一组非常复杂的滤波器，在频率基础上具有将输入信号进行放大和衰减的能力。

One way to look at it is that the modes of the system are nothing more than a very elaborate set of filters which have the ability to amplify and attenuate an input signal on a frequency basis.

对于两端固定输流管道在基础简谐激励下的单模态系统，利用凹槽滤波器对系统的混沌运动进行了控制。

The chaotic motion of a pipe single mode system of the fixed supported at two ends under base excitation is actively controlled by introducing the feedback of notch filter.
