Model Reference Adaptive Flutter Control of Pipes Transporting Fluid
並列摘要
Active vibration control of a cantilever pipe conveying fluid with flutter instability is presented in this work. A model reference adaptive control approach is applied, which uses time-varying feedback gains to synthesize the control action. The control input is provided by a pair of surface mounted piezoelectric actuators which are driven 180 degrees out of phase to provide an equivalent bending moment acting on the pipe system to be controlled. Performance of the control system for different flow speeds is examined. The effect of the gain constant on the performance of the adaptive system is studied. The influence of observer gains on the system dynamic behavior is investigated to enable a proper choice of gain parameters for efficient control of the unstable system. It is observed the presented control system can be successful for flutter suppression of the fluid-conveying cantilever pipe with a high flow speed.
