In this paper, we reformulate the aircraft scheduling problem as a mixed integer linear program (MILP) over runway configuration mode switches, under mixed operations with the objective of minimizing total delay. Furthermore, some appropriate wake vortex separation constraints is established, including Arrival-Arrival, Departure-Departure, Arrival-Departure, and Departure-Arrival for the different combinations. The performance of the proposed method is verified by experimentation with flight plans collected from the official database, which ensures research reliability. © 2023 IEEE.

The supercooled water droplets in the air will form a water film on the aircraft during flight, which will then form icing, which will have an impact on the aerodynamic performance of the aircraft and even endanger the flight safety. In this paper, based on the Eulerian Wall Films model, the partial wetting effect is introduced, and the water film flow on flat plates driven by airflow shear force is investigated. The flow behaviours of water film with different contact angles under different flow rates were explored through water film test. The effectiveness of the calculation method for water film flow characteristics in this paper was verified by comparison between numerical simulation and test records, which laid a foundation for the anti-icing calculation in subsequent studies. © The Institution of Engineering & technology 2024.

Reconfigurable Intelligent Surface (RIS) technology, closely integrated with Artificial Intelligence (AI) as one of the Physical Layer (PL) technology approaches, is considered an ef-fective solution for enhancing security in industrial Internet of Things (IIoT) networks. Integrating RIS, AI, and heterogeneous IIoT networks presents a promising approach to improving the se-curity of wireless communications in IIoT. This paper discusses new AI-based Physical Layer Authentication (PLA) approaches and how they can be integrated with RIS to enable identity authen-tication and malicious node detection, aiming to provide light-weight isolation in IIoT terminals. An anti-jamming and secure communication framework for IIoT is proposed, which leverages Deep Reinforcement Learning (DRL) and RIS to defend against malicious jamming and eavesdropping targeting legitimate users' channels. Additionally, a foundational framework that employs Quantum Reinforcement Learning (QRL) is presented to improve RIS-assisted secure communication. Furthermore, the threats posed by Generative AI (GAI) to RIS-assisted IIoT communica-tion networks and possible defense schemes are provided. Finally, the paper concludes by discussing research opportunities and fu-ture challenges. © 1986-2012 IEEE.

As one promising sensorless control algorithm, the nonlinear flux observer is widely used in industries. However, it is sensitive to parameter variations and the gradient search gain can greatly affect its stability. Therefore, this paper proposes an improved nonlinear flux observer, which corrects the stator flux estimation by adding an extended state observer (ESO) to reduce the parameter sensitivity. In addition, the position error compensation is realized by another ESO constructed in estimated rotation frame. The effectiveness of the proposed algorithm is verified experimentally.

When building complex systems, the design space of the system architecture needs to be modelled and fully expanded to support experts in making further decisions. The trend of more-electric aircraft (MEA) allows electric energy and electric actuators to replace part of hydraulic energy and hydraulic actuators, making the design of flight control systems (FCS) more and more complicated. In this paper, a representation and enumeration method of the architecture of the MEA flight control system based on the morphological analysis method is proposed. The morphological matrix is used to represent the structure of the system, and the enumeration method is used to obtain all possible architecture combinations. A method of determining whether a combination is expected to be generated is proposed. © 2022 IET Conference Proceedings. All rights reserved.

Security of information interactions and rapid emergence of self-organized behaviors are key factors for flocking control. With this in mind, the security predefined-time flocking control problem of networked agent systems is addressed in this paper. Theoretically, by utilizing the time-varying transformation function to hide the real state values of agents, an event-triggered-based control scheme with predefined-time convergence is designed. Firstly, a decentralized (executed separately by every agent) time-varying transformation is adopted to encrypt agents' real states. Thus, agents can encode their true states using unique keys, rendering initial states impervious to decipherable by others. On the basis, the predefined-time flocking controller is proposed such that self-organized behavior of agents emerges within a specified time. Furthermore, the utilization of event-triggered mechanism effectively alleviates the burden on the actuator caused by frequent updates, concurrently reducing communication computational resource consumption. Finally, some numerical simulations are performed to testify the effectiveness of proposed flocking control scheme.

Road obstacle detection is an important problem for vehicle driving safety. In this paper, we aim to obtain robust road obstacle detection based on spatio-temporal context modeling. Firstly, a data-driven spatial context model of the driving scene is constructed with the layouts of the training data. Then, obstacles in the input image are detected via the state-of-the-art object detection algorithms, and the results are combined with the generated scene layout. In addition, to further improve the performance and robustness, temporal information in the image sequence is taken into consideration, and the optical flow is obtained in the vicinity of the detected objects to track the obstacles across neighboring frames. Qualitative and quantitative experiments were conducted on the Small Obstacle Detection (SOD) dataset and the Lost and Found dataset. The results indicate that our method with spatio-temporal context modeling is superior to existing methods for road obstacle detection. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

The characteristics of energy feedback, high power mutation and constant power load of electro-hydrostatic actuator have impact on power supply network of aircraft. Based on the theoretical analysis, this paper establishes the layered model of electro-hydrostatic actuator and power supply network with energy characteristics for the first time, and determines the parameter setting method of key devices in the model. The motor speed and electromagnetic torque direction and energy transfer rule were obtained by simulation when electro-hydrostatic actuator was motoring or braking. Four Quadrant Operation of electro-hydrostatic actuator's impact on the power supply network is quantitative analyzed. In the case of no brake resistance, the energy feedback from electro-hydrostatic actuator makes the bus voltage of the power supply network of the aircraft far beyond the safe voltage range. Finally, the comprehensive effect of multiple electro-hydrostatic actuators on power supply network is analyzed. When multiple electro-hydrostatic actuators have the same operating instructions and the same loads, their impact on the power supply network will be superimposed. When multiple electro-hydrostatic actuators have opposite operating instructions and the same loads, their impact on the power supply network will be counterbalanced. The command of flight control actuation system and real-time aerodynamic load are the key factors affecting the impact of multiple electro-hydrostatic actuators on the power supply network. The results of this paper have guiding significance for restraining the impact of electric actuator energy consumption on the power supply network of aircraft. © 2022 IET Conference Proceedings.
