Special Issue Information

Dear Colleagues,

Unmanned Aerial Vehicles (UAVs), commonly known as drones, have rapidly evolved from niche tools to essential assets across a broad range of industries. UAVs are now integral to fields such as agriculture, surveillance, search and rescue, logistics, and environmental monitoring. A key factor driving their effectiveness is the adoption of intelligent control techniques, which enable UAVs to operate autonomously, adapt to dynamic environments, and perform complex tasks with high precision. As UAVs are often deployed in unpredictable or hazardous environments, traditional control methods are frequently insufficient to ensure reliability and safety. This is where intelligent control technologies, such as adaptive control, fuzzy logic, reinforcement learning, and neural networks, come into play. These methods allow for the UAVs to learn from their surroundings, make real-time decisions, and adjust their behaviors without human intervention, leading to improved mission success rates and operational efficiency.

The objective of this Special Issue is to explore the latest advancements in intelligent control techniques for UAVs, with an emphasis on algorithms, architectures, and applications that enhance the autonomy, reliability, and robustness of UAV systems. This Special Issue invites original research articles that contribute significantly to theoretical, numerical, and experimental developments in UAV control, as well as application-driven innovations. Review articles highlighting the state-of-the-art in UAV intelligent control are also encouraged.

Potential topics include, but are not limited to, the following:

  • Adaptive control techniques for UAVs;
  • Fuzzy logic and hybrid control systems;
  • Reinforcement learning and deep learning for autonomous UAVs;
  • Path planning and trajectory optimization;
  • Real-time decision-making algorithms;
  • Robust control for uncertain and dynamic environments;
  • UAV swarm intelligence and multi-agent systems;
  • Fault detection and diagnosis in UAV systems;
  • Sensor fusion and perception for autonomous flight;
  • Vision-based control for obstacle avoidance and navigation;
  • Safety and reliability analysis in UAV systems;
  • Autonomous UAVs for precision agriculture, disaster response, and surveillance;
  • Human–UAV interactions and collaborative systems;
  • 5G and IoT integration for UAV control systems;
  • UAV control in GPS-denied environments;
  • Advanced simulation models for UAV control and testing.

In complex environments, autonomous navigation for quadrotor drones presents challenges in terms of obstacle avoidance and path planning. Traditional artificial potential field (APF) methods are plagued by issues such as getting stuck in local minima and inadequate handling of dynamic obstacles. This paper introduces a layered obstacle avoidance structure that merges vortex artificial potential (VAPF) fields with reinforcement learning (RL) for motion control. This approach dynamically adjusts the target position through VAPF, strategically guiding the drone to avoid obstacles indirectly. Additionally, it employs the Twin Delayed Deep Deterministic Policy Gradient (TD3) algorithm to facilitate the training of the motion controller. Simulation experiments demonstrate that the incorporation of the VAPF effectively mitigates the issue of local minima and significantly enhances the success rate of drone navigation, reduces the average arrival time and the number of sharp turns, and results in smoother paths. This solution harmoniously combines the flexibility of VAPF methods with the precision of RL for motion control, offering an effective strategy for autonomous navigation of quadrotor drones in complex environments.

Unmanned Aerial Vehicle (UAV) path planning is critical for ensuring flight safety and enhancing mission execution efficiency. This problem is typically formulated as a complex, multi-constrained, and nonlinear optimization task, often addressed using meta-heuristic algorithms. The Crested Porcupine Optimizer (CPO) has become an excellent method to solve this problem; however, the standard CPO has limitations, such as the lack of adaptive parameter tuning to adapt to complex environments, slow convergence, and the tendency to fall into local optimal solutions. To address these issues, this paper proposes an algorithm named QCPO, which integrates CPO with Q-learning to improve UAV path optimization performance. Q-learning is employed to adaptively adjust the key parameters of the CPO, thereby overcoming the limitations of traditional fixed-parameter settings. Inspired by the porcupine’s defense mechanisms, a novel audiovisual coordination strategy is introduced to balance visual and auditory responses, accelerating convergence in the early optimization stages. A refined position update mechanism is designed to prevent excessive step sizes and boundary violations, enhancing the algorithm’s global search capability. A B-spline-based trajectory smoothing method is also incorporated to improve the feasibility and smoothness of the planned paths. In this paper, we compare QCPO with four outstanding heuristics, and QCPO achieves the lowest path cost in all three test scenarios, with path cost reductions of 30.23%, 26.41%, and 33.47%, respectively, compared to standard CPO. The experimental results confirm that QCPO offers an efficient and safe solution for UAV path planning. Full article

Consensus tracking control for multiple UAVs demonstrates critical theoretical value and application potential, improving system robustness and addressing challenges in complex operational environments. This paper addresses the challenge of event-triggered prescribed-time synchronization tracking control for 6-DOF fixed-wing UAVs with state constraints. We propose a novel prescribed-time command filtered backstepping approach to effectively tackle the issues of complexity explosion and singularities. By utilizing a state-transition function, we manage asymmetric time-varying state constraints, including limitations on speed, roll, yaw, and pitch angles in UAVs. The theoretical analysis demonstrates that all signals in the 6-DOF UAV system remain bounded, with tracking errors converging to the origin within the prescribed time. Finally, simulation results validate the effectiveness of the proposed control strategy. Full article
