摘要: The purpose of this paper is to investigate the dynamic behavior a fluid conveying pipe and propose suitable control strategies in order eliminate or suppress its vibration. system under consideration consists uniform, straight, vertical cantilever which conveys incompressible fluid. Governing equation motion for free transverse vibration derived by using Newtonian approach. This dis-cretized finite element method. effects flow speed on open loop response are investigated. results show unstable when velocity exceeds critical value. Neural network based controller applied improve stability conditions. that neural successfully suppresses exceeded. Moreover, it holds stable region at higher velocities. NN learns variation against unknown velocities adapts itself changes.
