摘要

针对具有不确定参数和外部干扰的柔性立管系统,提出了一种新的自适应约束控制方法,以达到期望的暂态性能。将Hamilton原理与偏微分方程相结合,将物理模型转化为动力学模型。考虑边界位置约束,利用切线势垒Lyapunov函数(BLF)建立边界控制器以减轻振动。为了保证边界位置误差以预定速率收敛,该控制方法引入了性能函数以获得所需的瞬态性能。定义了一个辅助项来抵消偏微分方程解耦过程中遗留的耦合项的影响。最后,通过MATLAB仿真对上述方案进行了进一步验证。

Adaptive State Constrained Control of a Flexible Riser System With Transient Performance
A novel adaptive constraint control approach is proposed for flexible riser systems characterized by uncertain parameters and external disturbances, aimed at achieving the desired transient performance. By combining Hamilton’s principle with partial differential equations (PDEs), the physical model is transformed into a dynamic model. Considering the boundary position constraint, a boundary controller is built using the tangent barrier Lyapunov function (BLF) to mitigate vibrations. In order to ensure the convergence of the boundary position error at a predetermined rate, the control approach incorporates a performance function to attain the necessary transient performance. An auxiliary term is defined to counteract the impact of coupling terms that remain during the decoupling process of PDEs. Finally, the above scheme is further validated through MATLAB simulations.
