In recent years, Unmanned Aerial Vehicles (UAVs) have been used in many fields by virtue of their flexible design, low cost and zero casualties. With the deepening application of UAVs, the tasks they undertake are gradually becoming more complex and can no longer be accomplished by a single UAV alone, so multiple UAVs are needed to collaborate in order to perform the tasks. In this paper, a UAV ground control station software system is designed for the characteristics of multiple UAVs to perform tasks. The system is designed with the key requirement of reducing the operator’s workload in mind, while taking into account the differences in control and surveillance between multiple UAVs and a single UAV. After defining the functional requirements of the ground control station, the development and implementation of the ground station software is carried out, and finally, an application example of the ground station software is presented. The experiments show that the proposed ground station has some engineering value. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

An empirical thrust model of dielectric barrier discharge (DBD) plasma actuator with good prediction performance is proposed on the basis of many of experimental data. The model considers six main parameters affecting the actuator thrust, including voltage peak value, frequency, the exposed electrode thickness, encapsulated electrode width and relative permittivity and thickness of dielectric. The estimated thrust value as a body force source term is inserted into the Reynolds-averaged Navier-Stokes equation which is solved by the CFD software FLUENT. The body-force region is specified by an empirical body-force distribution function based on velocity information. The effectiveness of the empirical model and body-force distribution is verified by different experimental cases. Thus, the proposed model can predict the thrust and velocity field generated by the DBD plasma actuator. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

The cooperative guidance issues for multiple missiles against a maneuvering target with collision avoidance and obstacle dodging mechanism are considered. Firstly, a fully head-on guidance law is designed by using backstepping control and trajectory shaping techniques, which provides a great reference trajectory for the leader missile. Secondly, based on the modified artificial potential field (MAPF) method, a novel collision avoidance and obstacle dodging strategies in the cooperative guidance process of follower missiles is proposed. The secure time-varying line of sight (LOS) angle formation tracking guidance law is then designed for follower missiles by using backstepping control frameworks and the repulsive force obtained by the MAPF method. Finally, two numerical simulation examples are conducted to illustrate the effectiveness of proposed secure cooperative guidance strategy. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Wet-type permanent magnet synchronous motors (WTPMSM) are extensively utilized to meet the power density requirements of electro-hydrostatic actuators (EHA), which are widely used in modern aircraft control systems. These motors are valued for their superior thermal performance and compact design. However, WTPMSM face a key challenge in the form of oil churning loss, especially within narrow air gaps. This churning loss can significantly impact the motor's performance and efficiency. In this paper, an analytical model has been established and computational fluid dynamics (CFD) has been employed to simulate the internal flow of the motor, thereby predicting the churning loss. The paper also investigates churning loss caused by the thread air gap in the wet motor, examining the effects of thread geometry, size, and motor speed on churning loss. Strategies such as optimizing thread design and adjusting operational parameters are proposed to mitigate churning losses. In summary, churning loss of WTPMSM is significantly influenced by the thickness of the air gap and the depth of the threads. These findings provide guidance for the design of electric motors. Future research should delve deeper into the specific impacts of various design parameters on churning losses and explore methods to reduce churning losses through enhanced motor design. © The Institution of Engineering & technology 2024.

The application of artificial intelligence makes the collaboration between machine and human closer in the future. How to build the architecture of human and machine collaboration and evaluate the profit of human and machine collaboration is the premise of promoting the effective application of artificial intelligence in flight control system. The paper proposes an architecture of human and machine collaboration, focusing on the method based on human-machine cognition and behavioral ability evaluation, and how to make task allocation between human and machine through the analysis of man-machine ability expertise and collaboration efficiency. Using NASA-TLX scale and objective metrics, an example of allocating the human and machine tasks during the design process of the flight control system using this architecture is proposed in the paper, showing the effectiveness of the architecture. © 2024, International Council of the Aeronautical sciences.

Air combat evaluation and analysis is of great significance to improve pilots’ air combat skills and capabilities. An air combat decision-making evaluation method based on the combination of fuzzy neural network and cloud model evaluation is proposed in this paper. First of all, the air combat index of each time is calculated. And then the air combat advantage at each time in the process of air combat is obtained by training the fuzzy neural network. After that the cloud model is applied to comprehensively evaluate the air combat decision, so as to complete the evaluation of the air combat decision. Finally the air combat case is used for evaluation, which verifies the effectiveness of the method. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

An improved algorithm based on the Grey Wolf optimizer (GWO) is addressed to generate the optimal path. Firstly, to use the optimization method to solve the path planning problem of UAV, the unconstrained path planning problem, and the constraints such as the no-fly area are abstracted as objective function and constraint function, respectively. Secondly, a penalty-based technique is applied to modify the extended cost function and the improved GWO is proposed to solve it. Finally, the result of digital simulation shows that the algorithm has good performance in the processing ability of constraint problems, convergence, and the robustness of globally optimal solutions. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

This paper mainly focuses on the target assignment problems in the unmanned aerial vehicle (UAV) swarm combat. Firstly, the idea of the multi-UAV swarm combat is shown and the constraints and the benefit matrix of the target assignment task are modeled. Secondly, a fixed-time consensus protocol is utilized to estimate the state of all the other agents and its convergence is proved by Lyapunov method. Then, a distributed compensation auction algorithm is proposed. Finally, the proposed distributed compensation auction algorithm is simulated and the results demonstrate the successful completion of the assignment task with only neighboring information. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Over the last decade, the relationship between humans and cyber-physical systems has grown closer, particularly in fields such as manufacturing and transportation. This paper presents a control framework within the engineering domain, wherein a human operator collaborates with a swarm of unmanned aerial vehicles (UAVs) to achieve a shared goal. First, we construct a human-swarm mutual trust model that empowers both parties with a degree of autonomy. Second, we adopt a distributed optimization algorithm integrated with control barrier functions to manage the swarm's motion. The cooperative control framework is demonstrated in a 3D scenario, and simulation results verify the feasibility of the proposed method. © 2024 IEEE.
