Abstract

Pipes with supported ends conveying pulsating fluid may lose the dynamic stability due to parametric instability, therefore the piezoelectric actuators are taken as the control actuators here for controlling vibration of pipeline. First, the controlled mathematical models of pipes conveying fluid were established. Second, model reference adaptive control (MRAC) system and MRAC system based on adaptive gain of the PD were designed. Third, the effects of controllers were verified and the effects of the control parameters on the controllers were analyzed also. During simulation, the time of vibration displacement decaying to zero, also the time and total energy of control input were taken as evaluation indexes. The results of numerical simulation showed that the pipeline vibration could be controlled well by the controllers which were designed by adaptive control strategy.
