摘要

研究了具有不确定参数和不可测状态的二维柔性立管系统的振动控制问题。提出了基于反步法的自适应输出反馈控制器来抑制隔水管系统的振动。为此，设计了参数自适应律来补偿系统参数中的不确定性。此外，还引入了高增益观测器和扰动观测器来估计和补偿环境载荷引起的不可测状态和时变边界扰动。用数学方法证明了闭环系统的适定性和稳定性。通过仿真对所提控制器的性能进行了评价。

Adaptive output feedback control for a two-dimensional flexible riser system based on backstepping method

This paper addresses the vibration control problem of a two-dimensional flexible riser system with uncertain parameters and unmeasurable states. Adaptive output feedback controllers are proposed based on the backstepping method to suppress the vibration of the riser system. To this end, parameter adaptive laws are designed to compensate for uncertainties in system parameters. Additionally, high-gain observers and disturbance observers are introduced to estimate and compensate for unmeasurable states and time-varying boundary disturbance caused by environmental loads. The well-posedness and stability of the closed-loop system are mathematically demonstrated. The performance of the proposed controllers is evaluated through simulation.
