Based on the analysis on system characteristics, a robust fixed gain PID controller and prefilter with optimum ITAE performance indicator are designed for a base speed.
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。

The mode shape of the system is different from that of the structure on the fixedbase in that there are rocking and swing at the foundation.
