本文研究了山东半岛沿岸海域航行中补给船同步控制问题,并解决网络攻击和干扰补偿引起的增益时变问题.首先,构造了干扰观测器以提供海洋中的时变干扰估计值,构造了自适应律实时更新未知控制参数;其次,通过将干扰观测器与矢量反步技术相结合,设计一种用于同步的抗干扰跟踪控制器;最后,在1:70比例的补给船模型上进行了仿真模拟.结果表明:抗干扰同步跟踪控制器能够实现补给船与被补给船的同步航行,并保证闭环同步跟踪控制系统中的所有信号全局一致最终有界.
Anti-disturbance Synchronization Control for Supply Ship in the Coastal Area of Shandong Peninsula
The synchronization control problem is investigated for supply ship in the coastal area of Shandong Peninsula in this paper,and the problem of the time-varying gain caused by cyber-attacks and disturbance compensation is solved.Firstly,a disturbance observer was designed to provide time-varying disturbance esti-mates in the ocean,and the adaptive law was constructed to update the unknown control parameters in real time;secondly,an anti-disturbance tracking controller for synchronization was designed by combining the dis-turbance observer with the vector backstepping technique;finally,simulations were conducted on a 1∶70 scale model supply ship.The results show that the anti-disturbance tracking controller can realize the synchronization navigation between the supply ship and the supplied ship,and all signals in the closed-loop synchronization tracking control system are global uniform ultimate boundedness.
