Robust flutter control of a vertical pipe conveying fluid using gyroscopic mechanism
- Tohoku Univ., Sendai (Japan). Inst. of Fluid Science
This paper presents a study on the flutter suppression of a cantilevered pipe conveying fluid by means of gyroscopic mechanism. One end of the pipe is fixed at the center of the gyroscopic mechanism and the two directional vibration of the pipe is controlled by the moments of two servomotors connected to the two axes of the gyroscopic mechanism. The present system with the servomotors is described approximately by two independent differential equations. The evaluation method of structured singular value is used to obtain a robust controller, and the unformulated dynamics (coupled motion of two directions, nonlinear effect etc.) is treated by the robust performance of controller. Numerical simulation and experimental results show that the flutter is effectively suppressed by the present method.
