However, in recent years, driven by factors, such as population growth and economic expansion, cultivated land has faced threats, including illegal occupation. Advanced technologies and equipment are essential for the protection and monitoring of cultivated land. Although satellite remote sensing technologies can periodically monitor cultivated land changes on a large scale, their timeliness and flexibility are limited by revisit cycles and weather conditions. Uncrewed aerial vehicles (UAVs) provide high-resolution imagery and a wide field of view in field surveys. However, current UAV-based systems often lack automated data processing and sufficient mobility, which limits operational efficiency. To address these issues, this article proposes and implements LandExplorer-CL, an integrated vehicle–UAV–cloud system for monitoring and verifying suspected illegal cultivated land occupation. The system integrates a ground vehicle with off-road mobility and an automated UAV docking station. Together, these components form a highly mobile and rapidly deployable intelligent operation platform. Through the design of a specialized target detection model, the system achieves high-precision detection of suspected illegal occupation targets in cultivated land. In addition, an intelligent land-cover change analysis framework enhanced with retrieval-augmented generation and large multimodal models is utilized to reduce hallucinations and dependence on massive labeled samples. Extensive experimental results demonstrate the practical effectiveness of this system in monitoring cultivated land change polygons in large-scale and complex rural environments.","PeriodicalId":55017,"journal":{"name":"IEEE Systems Journal","volume":"20 2","pages":"480-491"},"PeriodicalIF":4.9,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148510289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article examines the cascading effects of disruptions to semiconductor supply chains through a discrete event simulation (DES) framework. The paper explores two scenarios: 1) Weather-induced disruptions, such as extreme weather events that affect logistics and material availability, and 2) material supply shortages coupled with natural disaster risks, such as flooding and high winds. The approach describes how weather-related disruptions affect transportation and logistics, potentially leading to increased operational costs and delays, while material shortages impact production capacities directly. By employing DES, we assess the effectiveness of several mitigation strategies, including inventory management and supplier diversification. The results highlight the importance of adaptive strategies to enhance the resilience of semiconductor supply chains. The article, thus, illuminates complexities and interdependencies of these supply chains and provides insights for assuring supply chain functionality in the face of disruptions.","PeriodicalId":55017,"journal":{"name":"IEEE Systems Journal","volume":"20 2","pages":"528-539"},"PeriodicalIF":4.9,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148510689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address the nonsmooth control signals arising from this setup, a prescribed-time command filter is introduced to avoid explicit differentiation of virtual control signals and to generate smooth implementable reference derivatives. The framework also includes an event-triggered controller to reduce onboard computational resources.

First, the complicated nonlinear and underactuated characteristics of the multiple aerial transportation systems are managed through model transforming without any linearization, thereby retaining all dynamic model information. Second, a novel capsule bounding volume is developed that explicitly incorporates the payload state into the geometric encapsulation of each aerial transportation system, which reflects the specific payload state in anti-collision. Compared to existing methods, the proposed bounding volume method fully considers the system dynamics, which brings greater safety to real-world experiments. Furthermore, the proposed volume is more compact, thereby resulting in a larger solution space during motion planning. Then, an idea of scale is presented, which assists in the detection of collisions. Finally, the dynamics and all the constrains are equivalently transformed to formulate the to-be-solved optimal problem, which is finally solved by Gauss pseudospectral method-based algorithms. Comparative experiments verify that the proposed method yields safer and more aggressive trajectories than existing approaches, ensuring strict compliance with swing angle constraints even during time-optimal flight.","PeriodicalId":55017,"journal":{"name":"IEEE Systems Journal","volume":"20 2","pages":"407-414"},"PeriodicalIF":4.9,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148510691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effective and reliable control techniques are essential for maximizing the benefits of BD charging, particularly when integrating photovoltaic (PV) arrays and energy storage battery packs (ESBP) to alleviate grid strain. This article presents the design and implementation of a control technique, including the active decoupling dynamic reference current (DDRC) controller. The proposed controller incorporates a double PI control technique at both the front and back ends, combined with the DDRC technique, ensuring efficient control of the grid current, total harmonic distortion (THD), and DC-bus voltage. In addition, the V2G mode enhances grid stability during fluctuations in the grid. The system has been modeled in MATLAB/Simulink and validated using real-time experiments with a dSPACE (DS1104), and analysis is conducted on the IEEE 34-bus distribution system. The results validate that the proposed control technique effectively integrates EVs, PV arrays, and ESBP while maintaining power quality, focusing on THD and DC-bus voltage fluctuations, in compliance with IEEE 519-2014 standards. These results show that the proposed effective control technique enhances grid stability and power quality in BD charging applications.","PeriodicalId":55017,"journal":{"name":"IEEE Systems Journal","volume":"20 2","pages":"415-426"},"PeriodicalIF":4.9,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148510693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key innovation lies in integrating aerial wide-area coverage with precise ground positioning to design a point-area combined search mechanism. A dynamic Voronoi-based method is further adopted to enhance collaboration within heterogeneous systems. Considering the characteristics of the target search problem, an actor–critic framework is introduced for agent training, bidirectional information interaction is employed, and a multilevel feedback reward function is constructed to ensure efficient search performance in diverse environments. Experimental results show that BiF-AC improves the target search success rates by an average of 40.3% and reduces search steps by 21.3% compared with other baseline algorithms.

A Markov jump system framework is established to model abrupt mode transitions caused by stochastic events, such as line faults and lightning strikes in single-machine infinite bus systems. Considering practical delays between supervisory control and data acquisition-based mode detection and control implementation, an asynchronous control architecture is developed in which the controller runs under mismatched mode information. A data-driven Q-learning-based policy iteration algorithm is proposed to compute the optimal controller gains without requiring knowledge of system dynamics or mode transition probabilities. The algorithm relies solely on previously collected input-state data that satisfy a rank condition and converges to the model-based optimal solution. Simulation studies show that the proposed controller reduces transient state deviations by about 30% compared with an linear matrix inequalities-based asynchronous controller, ensuring stability and effective damping performance under both mode mismatch and system uncertainties.","PeriodicalId":55017,"journal":{"name":"IEEE Systems Journal","volume":"20 1","pages":"256-265"},"PeriodicalIF":4.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147727239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses on the distributed optimal consensus control problem of high-order nonlinear MASs with communication delays and disturbances, aiming to overcome the limitations of existing approaches. First, a PI variable incorporating communication delays is formulated using passive scattering transformation. Second, we achieve distributed optimization control for MASs with communication delays by applying scattering transformation techniques. Furthermore, this article proposes a PI regulator that integrates with Nussbaum functions to achieve optimal consensus for high-order nonlinear agents with unknown control directions and bounded external disturbances.
