中文摘要 |
针对具有系统结构参数不确定的海洋柔性立管不确定性系统, 为了提高其振动控制效果和品质, 通过对立管结构参数进行估计, 采用自适应控制技术和Lyapunov综合法, 设计了自适应边界控制算法对耦合内流动力学的立管振动进行控制. 所设计的自适应控制器能补偿系统参数不确定性, 以及避免了控制溢出, 并能保证系统的稳定性和一致有界性. 仿真结果进一步验证了该控制算法对抑制立管振动的有效性. |
英文摘要 |
To improve the effectiveness and quality of the vibration control for a flexible marine riser with the system parametric uncertainty, we estimate the parameters and employ the adaptive control technology and Lyapunov synthesis method to design an adaptive boundary controller to suppress the vibration of the riser coupled with internal fluid dynamics. With the proposed adaptive boundary control, system parameter uncertainty can be compensated, the control-spillover problem can be avoided, and the stability and uniform boundedness can be achieved. Simulation results demonstrate the effectiveness of the adaptive boundary controller to suppress the riser's vibration. |
