Air traffic control flow prediction is one of the key issues in aviation transportation management, crucial for optimizing resource allocation, enhancing control efficiency, and ensuring flight operation safety. This paper proposes a solution for air traffic control flow prediction based on big data analysis and machine learning techniques. Through extensive feature engineering and model construction using large-scale historical data, multiple prediction models including Support Vector Regression, Random Forest, Gradient Boosting Decision Tree, and an ensemble model were trained. Comprehensive performance evaluations using cross-validation and multiple metrics were conducted. Experimental results demonstrate that the proposed ensemble model effectively combines the strengths of multiple base models, significantly outperforming individual models in terms of prediction accuracy, stability, and generalization ability. This provides an efficient and reliable technical path for air traffic control flow prediction, with broad application prospects. © 2024 Copyright held by the owner/author(s).

An optimal control strategy for a hybrid power flow controller based on PST and VSC is proposed in this paper. Firstly, a power regulation model of the hybrid power flow controller considering the impedance variation with taps is established. Based on this, the power flow transfer factor between different lines is calculated for abnormal operation scenarios such as power grid maintenance and faults, and a power control strategy considering line thermal stability limit constraints is proposed. Then, combined with the regulation characteristics of the phase shifting transformer (PST) and voltage source converter (VSC), a coordinated control strategy for PST and VSC within the controller is proposed, which minimizes the number of mechanical tap adjustments for the PST and improves the service life of the equipment while meeting the demand for power flow regulation at different time periods. Finally, taking a regional power grid in Hebei Province as an example, the effectiveness of the proposed control strategy is verified.

The temperature control of spacecraft system level thermal vacuum testing used to be manually adjusted to the state of external heat flow and the working state of the single machine, so that the temperature of the spacecraft's single machine pulling deviation met the test requirements. In response to the time-consuming and labor-intensive situation of manually adjusting the temperature of multiple areas inside the spacecraft during thermal testing, this article identifies the controlled object based on the analysis of experimental data, and uses system simulation methods to explore the feasibility of closed-loop automatic control. The simulation results show that the PID plus nonlinear limiting controller has applicable robustness for temperature control inside the spacecraft thermal test chamber.

Transmission sections are critical components of regional interconnected power grids, and the reasonable distribution of power flow on these sections is significant for the stable and secure operation of the system. The Thyristor controlled Phase Shifting Transformer (TCPST), as a novel Flexible AC Transmission System (FACTS) device, can effectively improve power flow distribution on transmission sections. This paper focuses on the application of TCPST in optimizing power flow on transmission sections, selecting the load balancing degree and section losses as the control objectives for TCPST. A control strategy for optimizing power flow on transmission sections using TCPST is proposed and its effectiveness is verified through simulations on the PSCAD/EMTDC platform. The simulation results demonstrate that the proposed control strategy provides reasonable control objectives for TCPST applications in transmission sections, thereby improving power flow distribution and enhancing the reliability and safety of section operation.

The Density-Based Traffic Signal control System (DB-TSCS) is an innovative approach to manage traffic flow at intersections. Incorporating advanced sensor technologies and intelligent algorithms, the system adjusts the signal timings dependent on the traffic density at a particular point in time. This provides improvements in the flow of traffic while reducing the level of traffic congestion and improving the use of the transportation system in general. The central control unit uses density-based algorithms to analyze traffic conditions, generating optimized signal timings that prioritize congested directions while minimizing delays in low-density areas. The system also incorporates adaptive learning and can be integrated with smart city infrastructure for communication and real-time traffic updates. © 2025 IEEE.

Ensuring the robust performance of avionics systems demands meticulous attention to worst-case execution time (WCET) analysis. This is especially important in multicore environments where execution time can vary widely. This paper examines the interplay between data flow and control flow analysis within the context of avionics multicore systems, proposing a comprehensive solution for efficient WCET estimation. Drawing from industry standards such as A(M)C 20-193 [2] [3] and DO-178C/ED-12C [1], our approach emphasizes the integration of data flow and control flow analysis to accurately assess task execution times, thereby enhancing system reliability and safety. Additionally, this paper includes calculations of WCET using two different combinations of hardware and real time operating systems (RTOS) to illustrate the importance of considering the different characteristics of an environment in measuring this crucial timing. © 2024 IEEE.

Multi-architecture power distribution strategy for flexible DC interconnection system considering the capacity limitation

The flexible DC interconnection system, which cascades and unitedly controls several converter stations, can effectively improve the new energy consumption and significantly increase the power quality, thus has been widely used in the power grid. This interconnection system generally uses master-slave control strategy, where chooses one station as the master station to ensure the direct-side voltage's stability and maintain the input and output power balance. However, in some emergency cases, the input or output power can increase to a huge value that even exceeds the capacity of the master station, which not only threatens the safety of the master station but also leads to power imbalance and abnormal fluctuation of the direct-side voltage. Therefore, to avoid the capacity exceedance of the master station, a multi-architecture power distribution strategy is proposed in this study, which sufficiently considers the capacity limitation in the system architecture and innovatively prioritizes the capacity factor in the control strategy of the master station. Furthermore, the proposed strategy also fully considers cases where the system contains different types of slave stations, such as the station with redundant power and the station that can support bidirectional power flow. The strategy then optimizes the power distribution and adjusts the power flow based on the system's different architectures. The reliability and effectiveness of the proposed strategy are finally verified by simulation.(c) 2022 The Author(s). Published by Elsevier Ltd.

Dual active bridge converter is widely used in electric vehicle charging infrastructure, Data centers etc. due to the added advantages of inherent soft-switching, galvanic isolation and bidirectional power flow capability. Power flow is controlled by changing the phase shift angle between switching pulses of primary and secondary side converters. In this paper, design considerations of dual active bridge are presented along with different phase shift control techniques such as Single phase shift, Extended phase shift and Dual phase shift control technique and are compared on the basis of total harmonic distortion of the inductor current waveform which contributes to higher device stress and losses. Maximum achievable load with the given switching frequency and inductance is determined for optimized performance of the converter. The performance comparison of various control techniques have been performed in MATLAB/Simulink. © 2024 IEEE.

This work presents a numerical study on the passive control of a fluid flow coupled with convective heat transfer by using the lattice Boltzmann method. The study focuses on simulating the fluid flow and temperature distribution around a heated square cylinder controlled by three partitions and placed in a two-dimensional channel (Figure 1) at a fixed Reynolds number (Re =160). The addition of the partitions allows to control the vortex shedding, reduces the fluidic forces applied to the cylinder and improves the heat transfer characteristics around the square cylinder. The effects of the location and length of the partitions on the streamlines, isotherms and drag force are studied. The results obtained show that the inclusion of partitions leads to a 51.23% reduction in the drag coefficient and allows significant heat exchange. © 2023 IEEE.
