【摘要】：考慮了海洋柔性立管在時(shí)變內(nèi)流和海流作用下二維振動(dòng)控制問(wèn)題。柔性立管系統(tǒng)動(dòng)力學(xué)行為由兩個(gè)偏微分方程和六個(gè)常微分方程描述。為提高其振動(dòng)控制效果并避免控制溢出,直接基于其無(wú)限維分布參數(shù)模型,利用Lyapunov直接法和高增益觀測(cè)器技術(shù)研發(fā)了輸出反饋邊界控制來(lái)控制立管的二維振動(dòng)。隨后證明了海流擾動(dòng)作用下控制系統(tǒng)的一致最終有界穩(wěn)定性和閉環(huán)狀態(tài)的一致有界性。最后,仿真結(jié)果驗(yàn)證了文中所設(shè)計(jì)二維輸出反饋邊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.
