Such configuration follows a sensing-communication-computingcontrol (SC3) closed loop. To optimize the whole closed-loop performance, this paper minimizes the linear quadratic regulator (LQR) control cost by designing the sensor-to-EIH bandwidth allocation. Specifically, we first model the distortion noise caused by limited communication data rate based on the mutual information theory. Next, under the control policy based on the Kalman filter and LQR controller, we formulate the control process as a partially observable Markov decision process (POMDP), and develop a deep reinforcement learning (DRL)-based sensor-to-EIH bandwidth allocation scheme. The proximal policy optimization (PPO) algorithm is utilized to train the DRL agent. Simulation results are provided to show the superiority of the proposed DRL-based scheme.  \nIndex Terms—Bandwidth allocation, edge information hub (EIH), linear quadratic regulator (LQR), sensingcommunication-computing-control (SC3) closed loop.  \nI. INTRODUCTION  \nTHANKS to the advances in robotics and artificial in  \ntelligence, autonomous robots are increasingly deployed in remote areas to perform mission-critical tasks, such as emergency rescue [1], scientific exploration, and oil extraction [2] . These robots usually rely on sensors to obtain global environmental information and communication networks to enable information exchange [3] . However, the terrestrial infrastructures are usually unavailable to serve robots in remote areas due to the harsh geographical conditions. In such scenarios, autonomous aerial vehicles (AAVs, also known as UAVs) can be equipped with devices integrating communication and computing modules that serve as edge information hubs (EIHs) to provide edge intelligence for the robots [4] . In addition, a digital twin can be deployed on the EIH, as a virtual representation of the physical control system [5], [6] . During the control process, the sensors collect environmental information and transmit it to the EIH. Subsequently, the  \nC. Lei, W. Feng, and N.

These control commands are then transmitted to the robots to guide their actions. The above process is performed periodically, forming a sensingcommunication-computing-control (SC3 ) closed loop [7] . The overall performance and reliability of the robotic tasks depend critically on the efficiency and integrity of the SC3 closed loop.  \nDue to the inherent limitation on the payload capacity of UAVs, the communication","cbCaihsZ2FfjmkJV","https://ap.wps.com/l/cbCaihsZ2FfjmkJV","pdf",1311675,1,15,"English","en",105,"# Introduction\n# Related Works","[{\"question\":\"Which learning and control components are used to realize the approach?\",\"answer\":\"The control process is modeled as a POMDP and solved using deep reinforcement learning with a PPO-trained agent, while the underlying control policy uses a Kalman filter combined with an LQR controller.\"}]",1784194954,38,{"code":4,"msg":30,"data":31},"ok",{"site_id":24,"language":23,"slug":32,"title":13,"keywords":33,"description":14,"schema_data":34,"social_meta":78,"head_meta":80,"extra_data":82,"updated_unix":27},"deep-reinforcement-learning-empowered-wireless-sensor-networking-for-6g-closed-loop-controls","",{"@graph":35,"@context":77},[36,53,68],{"@type":37,"itemListElement":38},"BreadcrumbList",[39,43,47,50],{"item":40,"name":41,"@type":42,"position":20},"https://docshare.wps.com","Home","ListItem",{"item":44,"name":45,"@type":42,"position":46},"https://docshare.wps.com/document/","Document",2,{"item":48,"name":12,"@type":42,"position":49},"https://docshare.wps.com/document/research-report/",3,{"item":51,"name":13,"@type":42,"position":52},"https://docshare.wps.com/document/deep-reinforcement-learning-empowered-wireless-sensor-networking-for-6g-closed-loop-controls/84344/",4,{"url":51,"name":13,"@type":54,"author":55,"headline":13,"publisher":57,"fileFormat":60,"inLanguage":23,"description":14,"dateModified":61,"datePublished":62,"encodingFormat":60,"isAccessibleForFree":63,"interactionStatistic":64},"DigitalDocument",{"name":9,"@type":56},"Person",{"url":40,"name":58,"@type":59},"DocShare","Organization","application/pdf","2026-07-17","2026-07-16",true,{"@type":65,"interactionType":66,"userInteractionCount":20},"InteractionCounter",{"@type":67},"ViewAction",{"@type":69,"mainEntity":70},"FAQPage",[71],{"name":72,"@type":73,"acceptedAnswer":74},"Which learning and control components are used to realize the approach?","Question",{"text":75,"@type":76},"The control process is modeled as a POMDP and solved using deep reinforcement learning with a PPO-trained agent, while the underlying control policy uses a Kalman filter combined with an LQR controller.","Answer","https://schema.org",{"og:url":51,"og:type":79,"og:title":13,"og:site_name":58,"og:description":14},"article",{"robots":81,"canonical":51},"index,follow",{"doc_id":7,"site_id":24},{"code":4,"msg":5,"data":84},[85,89,93,97,102,107,112,115,120,123,127],{"id":20,"doc_module":4,"doc_module_name":45,"category_name":86,"show_sort_weight":87,"slug":88},"Story & Novel",90,"story-novel",{"id":46,"doc_module":4,"doc_module_name":45,"category_name":90,"show_sort_weight":91,"slug":92},"Literature",80,"literature",{"id":52,"doc_module":4,"doc_module_name":45,"category_name":94,"show_sort_weight":95,"slug":96},"Exam",70,"exam",{"id":98,"doc_module":4,"doc_module_name":45,"category_name":99,"show_sort_weight":100,"slug":101},5,"Comic",60,"comic",{"id":103,"doc_module":4,"doc_module_name":45,"category_name":104,"show_sort_weight":105,"slug":106},6,"Technology",50,"technology",{"id":108,"doc_module":4,"doc_module_name":45,"category_name":109,"show_sort_weight":110,"slug":111},7,"Healthcare",40,"healthcare",{"id":11,"doc_module":4,"doc_module_name":45,"category_name":12,"show_sort_weight":113,"slug":114},30,"research-report",{"id":116,"doc_module":4,"doc_module_name":45,"category_name":117,"show_sort_weight":118,"slug":119},9,"Religion & Spirituality",20,"religion-spirituality",{"id":118,"doc_module":4,"doc_module_name":45,"category_name":121,"show_sort_weight":118,"slug":122},"World Cup","world-cup",{"id":124,"doc_module":4,"doc_module_name":45,"category_name":125,"show_sort_weight":124,"slug":126},10,"Lifestyle","lifestyle",{"id":128,"doc_module":4,"doc_module_name":45,"category_name":129,"show_sort_weight":98,"slug":130},19,"General","general"]
