Network-assisted full-duplex (NAFD) cell-free massive multiple-input–multiple-output (MIMO) systems, which virtually achieve FD transmission by employing half-duplex access points (APs) to simultaneously serve uplink (UL) and downlink (DL) users on the same frequency bands, can decrease latency and enhance reliability since self-interference cancellation is unnecessary and macrodiversity is provided, thus helping industrial ultrareliable low-latency communication applications. In this article, we consider a monitoring scenario of industrial automation in NAFD cell-free systems using finite blocklength codewords and analyze UL and DL signals, end-to-end (E2E) delay, and E2E decoding error probability (DEP). Then, an optimization problem is formulated to minimize the maximum E2E DEP among all actuators by jointly designing AP working mode, UL and DL blocklengths under the E2E delay constraint. We propose the estimation of distribution algorithm-differential evolution (EDA-DE) method with low complexity to obtain a near-optimal solution, where the block coordinate descent is used to divide this problem into two parts. The first AP working mode selection is solved by EDA, and the second UL and DL blocklengths are designed by DE. Simulation results indicate that the performance of our proposed EDA-DE method is close to that of exhaustive search with lower computational complexity.

This article investigates a prescribed-time method for multiple fixed-wing autonomous aerial vehicles (AAVs) to enclose and track a moving target based on relative measurements. Utilizing onboard sensors brings two main challenges, i.e., maintaining the target within the field-of-view and tracking a noncooperative target with limited information. To this end, a prescribed-time enclosing and tracking controller is proposed first, guaranteeing that multiple fixed-wing AAVs converge to the desired trajectories within a prescribed time subject to motion and visibility constraints. Then, considering the dilemma of the input saturation and prescribed-time convergence, a basis for selecting the proper prescribed time is analyzed by mathematical formulations. It is determined by different initial states and constraints rather than arbitrarily. Finally, comparison and simulation results verify the effectiveness of the proposed method within a prescribed time.

Based on model predictive control and an attack detection mechanism, the stabilization problem of a class of nonlinear discrete-time cyber–physical systems with deception attacks at the sensor-to-controller and controller-to-actuator communication channels is studied. In this article, the deception attacks on both ends of the controller are considered using a more generic probability model. Attack detection models and mechanisms are established to detect the integrity of transmitted information in order to mitigate the impact of deception attacks. To ensure the input-to-state practical stability of the closed-loop system, a model predictive controller is designed based on the detected state. Finally, a simulation case is presented to demonstrate the stability and effectiveness of the proposed method.

Despite great progress in modeling the resilience response of power systems under extreme events, it remains difficult to assess the evolutionary trend of system performance at a specific observation moment during such events. Conventional simulation-based assessment methods are typically time-consuming because a series of scenario-specific optimization problems must be solved as a prerequisite. Thus, a spatial-temporal graph-based approach is proposed for fast resilience assessment to provide timely warning information. The key factors, including observable meteorological information, component vulnerabilities, emergency dispatch, and repair strategies, are modeled in the form of matrices that depict the spatial and temporal relationships. Based on these matrices, a spatiotemporal graph neural network is developed to fit the mapping relationship between observable states and resilience indicators, which is trained offline and enables fast assessment via forward inference. Regarding the uncertainties of various extreme scenarios, the evaluation procedure combines the whole-process simulation and single-state replay technologies, which can respectively consider the uncertainties and provide deterministic data labeling for assessment. Finally, the effectiveness of the proposed method is verified on the benchmarks, including the IEEE 118-bus system and a realistic 2868-bus system.

In this article, we study a distributed multiscale formation optimization problem for the multiagent system. The global cost function is subjected to a constraint with an aggregative item, which reveals the degree of aggregation for the multiagent system. A distributed strategy is proposed to optimize the formation configuration at multiple scales, including the position, angle, and size of the formation configuration. The strategy first employs observation and parameter projection technologies to search for the optimal size. Then, it utilizes the gradient and moment to optimize the position and angle of the formation configuration synchronously. Finally, some simulation results are provided to verify the proposed strategy.

Failure modeling and analysis are essential to the reliable and safe operation of unmanned combat system, which ultimately influence the success of a mission. Previous studies mainly focus on failure modeling and analysis of unmanned systems in a single domain, where synergy of cross-domain unmanned combat has rarely been considered. In this study, a multilayered heterogeneous network model for cross-domain unmanned combat system has been developed. In addition, the logistic support, which is another key aspect of any combat is incorporated. Given the interdependencies among the layers considering logistic support and cross-domain synergy, importance measure-based malicious attack model is proposed to reflect the intensive dynamics and high uncertainties under modern combat environment. Then, cascading failure analysis based on load-capacity model is conducted, which provides a load redistribution method considering cross-domain synergy. Finally, a case study is given for demonstration and verification, where the number of kill chains and load entropy are adopted as performance indicators.

Besides, we find there is a flawed equality, in which some terms are inaccessible to the user. This flaw results in the failure for the user to finish his computations.
