Abstract This paper considers the guidance issue for attackers against aircraft with active defense in a two-on-two engagement, which includes an attacker, protector, defender and target. A cooperative line-of-sight scheme prescribed performance input saturation is proposed utilising sliding mode control theories, guarantees that attacker able to capture target assistance of protector remaining on between order intercept defender. fixed-time function first-order anti-saturation auxiliary variable are designed game strategy constrain overshoot satisfy requirement overload manoeuver. The alleviates influence external disturbance by implementing observer chattering phenomenon caused sign function. Finally, nonlinear numerical simulations verify strategies.

Abstract In recent years, the rapid convergence of artificial intelligence (AI) and low-altitude flight technology has driven significant transformations across various industries. These advancements have showcased immense potential in areas such as logistics distribution, urban air mobility (UAM) national defense. By adopting AI technology, can achieve high levels automation operate coordinated swarms, thereby enhancing efficiency precision. However, these technologies become more pervasive, they also raise pressing ethical or moral concerns, particularly regarding privacy, public safety, well risks militarisation weaponisation. issues sparked extensive debates. summary, while integration presents revolutionary opportunities, it introduces complex challenges. This article will explore opportunities challenges depth, focusing on privacy protection, military applications legal regulation, propose strategies to ensure that technological remain aligned with principles.

Recent advancements in autonomous mobile robots (AMRs), such as aerial drones, ground vehicles, and quadrupedal robots, have significantly impacted the fields of infrastructure inspection, emergency response, surveillance. Many these settings contain multiple moving elements usually neglected planning process. While a large body work covers topics addressing scenarios with stationary objects, promising dynamic points interest has only recently gained traction due to computational complexity. The nature problem brings it challenges motion prediction, real time adaptability, efficient decision-making, uncertainty. Concerning while constrained computationally, good understanding relative simplicity their platform gives way more complex prediction algorithms needed objects. This paper presents survey current state-of-the-art solutions path for object inspection using drones. presented approaches cover intention obstacle avoidance, environments, well agents. Potential future trends were identified primarily form heuristic learning methods, probabilistic algorithms, further specialization regard every scenario.

Networked cooperation of multi-unmanned-aerial-vehicle (UAV) is significant, but their cooperative guidance presents challenges due to weak cross-domain communication. Given the difficulties in information transmission security, this paper proposes a prescribed-time law (PTCGL) for networked multiple UAVs with intermittent Supported by directed internal communication, proposed PTCGL can ensure simultaneous arrival case pinning external communication time-triggered intermittent. In first stage, designed combine time-scaling function and second-order consensus. With desired convergence performance, time be pre-specified independent initial conditions parameter tuning theory. second begin suitable at prescribed time, are organized proportional navigation guidance, so as regardless Finally, simulations conducted verify effectiveness robustness law.

The study of unmanned aerial vehicle (UAV) coverage path planning is great significance for ensuring maritime situational awareness and monitoring. In response to the problem multi-region surveillance in complex obstacle environments, this paper proposes a global method capable simultaneously addressing multiple traveling salesman problem, avoidance problem. Firstly, salesmen problem–coverage (MTSP-CPP) model with objective minimizing maximum task completion time constructed. Secondly, calculating obstacle-avoidance costs based on Voronoi diagram proposed, laying foundation obtaining optimal access order. Thirdly, an improved discrete grey wolf optimizer (IDGWO) algorithm integrated variable neighborhood search (VNS) operations proposed perform assignment UAVs achieve workload balancing. Finally, dynamic programming, points area are solved precisely generate globally path. Through simulation experiments scenarios varying scales, effectiveness superiority validated. experimental results demonstrate that can effectively solve MTSP-CPP environments.
