| 英文摘要 |
| For the multiple unmanned surface vehicle system with incomplete sensing information, the model parameters
uncertainty, and the marine environment disturbance, a distributed hierarchical cooperative target estimation and tracking
control structure is proposed. At the communication level, a distributed extended state observer based on the unidirectional
communication topology is designed. The speed and location of noncooperative target are estimated. At the control
level, a reduced-order extended state observer requiring only relative distance is designed, while not only realizes the
synchronous estimation of the unknown dynamic uncertainty, but also simplifies the structure of the observer. In this paper,
an anti-disturbance position tracking control law based on the reduced-order extended state observer is designed to improve
the anti-interference ability of the cooperative target tracking control system is improved. The input-to-state stability of
the closed-loop system is analyzed via cascade theory. Besides, the tracking errors are uniformly ultimately bounded.
Simulations verify the effectiveness of the proposed control method. |
