| 摘要: |
| This paper considers the tracking problem of a fleet of unmanned surface vehicles (USVs) subject to low state feedback
frequencies, disturbances, and communication delays. Influenced by the high computational complexity of localization algorithms,
the low-frequency state feedback brings challenges in fulfilling the high-frequency control requirement for USVs.
Therefore, a novel self-triggered distributed model predictive control (ST-DMPC) approach, with a codesign dual-model
control strategy, is proposed. By simultaneously optimizing control inputs and triggering intervals, this approach achieves
expected control performance comparable to high-frequency control under lowstate feedback frequencies. Furthermore, sufficient
conditions for ensuring recursive feasibility and closed-loop system stability are derived. Finally, a numerical experiment
and comparison study are conducted to demonstrate the efficacy of the proposed approach. |
