【摘要】：考虑了海洋柔性立管在时变内流和海流作用下二维振动控制问题。柔性立管系统动力学行为由两个偏微分方程和六个常微分方程描述。为提高其振动控制效果并避免控制溢出,直接基于其无限维分布参数模型,利用Lyapunov直接法和高增益观测器技术研发了输出反馈边界控制来控制立管的二维振动。随后证明了海流扰动作用下控制系统的一致最终有界稳定性和闭环状态的一致有界性。最后,仿真结果验证了文中所设计二维输出反馈边界控制算法的有效性。
[Abstract]:The two-dimensional vibration control of a flexible riser with time-varying currents and currents is considered. The dynamic behavior of flexible riser system is described by two partial differential equations and six ordinary differential equations. In order to improve the vibration control effect and avoid the overflow, the output feedback boundary control is developed based on the infinite dimension distributed parameter model and the Lyapunov direct method and the high gain observer technology to control the two-dimensional vibration of the riser. Then the uniform ultimate bounded stability and the uniform boundedness of the closed-loop state of the control system under the current disturbance are proved. Finally, the simulation results verify the effectiveness of the proposed two-dimensional output feedback boundary control algorithm.
