飞机输流管道振动的最优控制

Optimal Control of Vibration in Fluid Conveying Pipe

研究了飞机输流管道振动的最优控制问题。对于具有弹性支承和非线性运动约束的悬臂输流管道 ,使用压电片作为控制执行元件 ,推导了受控输流管的运动方程 ,设计了振动的最优控制器 。

Optimal control method of vibration in a cantilevered pipe conveying fluid, with spring support and nonlinear motion constraint, was investigated theoretically. The equations of motion of controlled system that uses a piezoelectric actuator were derived. The optimal controller was designed. The effect of control method presented in this paper was examined by using numerical simulation.
