【摘要】：针对耦合时变内流和洋流动力学的海洋柔性立管系统,为有效抑制其振动和避免控制溢出问题,基于立管原始无限维模型,将边界控制技术与高增益观测器相结合,设计了边界控制器对立管振动进行主动控制,通过严格的数学分析,验证了控制作用下立管系统的稳定性和闭环系统状态的一致有界性。仿真结果验证了所设计边界控制算法对立管振动抑制的有效性。
[Abstract]:For the flexible riser system with coupled time-varying internal and ocean currents dynamics, in order to effectively suppress its vibration and avoid overflow, the boundary control technique is combined with the high-gain observer based on the original infinite dimension model of riser. A boundary controller is designed for active control of tube vibration. Through strict mathematical analysis, the stability of riser system under control and the uniform boundedness of closed loop system are verified. The simulation results verify the effectiveness of the proposed boundary control algorithm for the suppression of tube vibration.
