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.
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。

Synchronous rectification produces a ripple frequency twice that of the excitation frequency and thus is easier to remove with a lowpass filter.
