The proposed distributed control structure explicitly accounts for both the dynamic and kinematic subsystems of each SV agent. It features a hierarchical control design, where the outer loop generates high-level desired trajectories for each vehicle, and the inner loop employs an actor/critic RL strategy to derive the optimal low-level control scheme. In contrast to conventional back-stepping-based formation control methods, this approach independently addresses the dynamic and kinematic subsystems of each SV agent, enabling a more modular and robust analysis. Rigorous stability proofs are provided to ensure that tracking errors and learning errors for both individual agents and the overall closed-loop control system are uniformly and ultimately bounded (UUB). To validate the effectiveness and practicality of the proposed strategy, simulation studies are conducted with a group of five SVs, demonstrating superior performance and feasibility in achieving robust formation control under perturbations.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"200 ","pages":"Article 106077"},"PeriodicalIF":2.1,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143697223","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 proposed gradient-tracking algorithm introduces an auxiliary variable to add momentum towards the optimal state. We prove that this solution is all-time feasible, implying that the coupling constraint always holds along the algorithm iterative procedure; therefore, the algorithm can be terminated at any time. This is in contrast to the ADMM-based solutions that meet constraint feasibility asymptotically. Further, we show that the proposed algorithm can handle possible link nonlinearity due to logarithmically-quantized data transmission (or any sign-preserving odd sector-bound nonlinear mapping). We prove convergence over uniformly-connected dynamic networks (i.e., a hybrid setup) that may occur in mobile and time-varying multi-agent networks. Further, the latency issue over the network is addressed by proposing delay-tolerant solutions. To our best knowledge, accelerated momentum-based convergence, nonlinear linking, all-time feasibility, uniform network connectivity, and handling (possible) time delays are not <em>altogether</em> addressed in the literature. These contributions make our solution practical in many real-world applications.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"199 ","pages":"Article 106062"},"PeriodicalIF":2.1,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143592844","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}
