Active flutter suppression of a tube conveying fluid

This paper presents the flutter suppression of a cantilevered pipeconveying fluid. The response of the cantilevered pipe is controlled by the torqueproduced by a pair of tendons attached to the pipe and a servomotor. The equation ofmotion is solved by means of the Galerkin method. To reduce the number of systemmodes, a suboptimal control law is used. The good agreement between the numericaland experimental results show that this method is effective for the flutter suppressionof the cantilevered pipe conveying fluid.
