Multi-aircraft swarm and autonomous collaboration are inevitable trends in future development, and this paper mainly studies the multi-aircraft cooperative trajectory planning problem model and collaborative search algorithm. Based on the traditional single path planning method, a collaborative trajectory planning strategy is proposed. Based on the spatiotemporal requirements of collaborative tasks, a constraint model is established, and a cooperative path cost model is established by comprehensively considering path synergy and flyability, so as to complete the modeling of path planning problems for collaborative tasks. Aiming at the initial divergence problem in traditional collaborative path planning, a collaborative range model that is updated synchronously with node search is proposed, and an improved cooperative A* path planning algorithm is proposed, which realizes path planning for multi-aircraft collaborative missions. Based on the typical mission environment, the proposed method is simulated, and the feasibility and correctness of the proposed algorithm for solving the multi-aircraft cooperative trajectory planning problem under complex space-time constraints are verified. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

A collaborative search planning method based on an information map is proposed for the problem of multi-moving target detection in gray areas using a heterogeneous UAV swarm. This method takes into account the detection probability and false alarm probability of sensors, the heterogeneity and flight constraints of UAVs, and the random movement of targets. The mathematical planning model for the collaborative search of multiple UAVs is built by balancing short-term gain, long-term gain, and coordination gain. An information map for search is designed, incorporating target existence probability, environmental uncertainty, and revisiting pheromones. Different planning schemes are designed based on the heterogeneous characteristics of UAVs. Through numerical simulations in typical collaborative search scenarios, the effectiveness of the proposed method is validated. The simulation results show that the proposed method can make search trajectory decisions for each UAV within seconds. The organic combination of short-term, long-term, and coordination gain can guide the UAV swarm to capture more targets. Comparative simulation results demonstrate that the proposed method can capture more targets with fewer false alarms, effectively improving the task efficiency of heterogeneous multi-UAV collaborative search. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Planetary surface is a complex unstructured environment with strong light, strong shadows, weak textures and numerous obstacles. There is no GPS signal support and satellite networking support on the planetary surface. The limited computer and sensor capabilities of planetary rover have a significant gap from the ground autonomous driving configuration, which presents a great challenge to the autonomous navigation methods of planetary rover. Extreme lighting conditions will increase the camera mismatching rate, and poor texture will increase the lidar matching error, which will reduce the estimation accuracy. Moreover, camera and lidar produce great motion distortion in the rugged terrain and bumpy environment, which leads to a large increase in the cumulative error of odometer. Camera and lidar are not suitable as the main sensor of SLAM algorithm in unstructured environment because they are sensitive to the change of environment. Therefore, an autonomous navigation method for planetary rover based on multi-modal fusion and multi-factor graph optimization is presented in this paper. The IMU (Inertial Measurement Unit) odometer node is added to the lidar odometer and visual odometer thread, and the IMU is taken as the central node to build a multi-factor graph optimization model. A multi-factor graph optimization model and a strong adaptive constraint strategy with reasonable weights are constructed. The pose estimation of other sensors is used to constrain IMU bias, meanwhile historical rut tracking, obstacle contour matching and skyline feature matching are introduced. Finally, motion prediction is achieved in the IMU odometer node. Simulation results and field tests show that this method can effectively cope with the unstructured environment on planetary surface, which achieves adaptive and robust autonomous navigation of planetary rover. © Published under licence by IOP Publishing Ltd.

Aiming at the lack of frequency support capability of conventional wind turbines and the stability problem under weak grid, this paper gives a voltage source control strategy for full-power wind turbines. The grid-side converter adopts the principle of virtual self-synchronization to achieve grid-connection without phase-locked loop, and the machine side adopts the optimal speed to formulate the control strategy, while the bus voltage control strategy is added to achieve the deep coupling between the machine side and the grid side and the inertia transfer function provided. Under the described control strategy, the full-power wind turbine can provide significant inertia response. The article carries out a stability analysis of the system based on the Nyquist criterion of the open-loop transfer function. Finally, a full DC wind farm simulation example is constructed by PSCAD/EMTDC simulation software to verify the effectiveness of the proposed control method and the correctness of the theoretical analysis. © Beijing Paike Culture Commu.

This article proposes a formation control scheme based on L1 guidance law for fixed wing unmanned aerial vehicle clusters while considering collision avoidance issues between them. The fixed wing aircraft cluster adopts L1 guidance and tracking method to track their respective desired waypoints. By controlling the speed of the fixed-wing UAVs, the entire cluster forms a formation configuration on their individual desired trajectories. During the formation and transformation processes, an improved artificial potential field method is proposed based on the characteristics of fixed-wing UAVs to achieve collision avoidance between clusters. The effectiveness of the proposed approach is validated through numerical simulations based on a six-degree-of-freedom nonlinear UAV model, providing a reference for practical engineering applications. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
