| Abstract: |
| In this paper, we solve the cooperative path optimization problem of multiple unmanned aerial vehicles (UAVs) when searching for maritime targets. First, we analyze the problem in detail by modeling its basic elements. Next, based on updated results from the detection process, we use the consensus theory with a state predictor to fuse the UAV target probability maps. Lastly, we use distributed model predictive control (DMPC) to optimize the UAV searching routes and simultaneously introduce local and future searching rewards. The simulation results indicate that the searching efficiency of our proposed method is higher than that achieved by current techniques. |
