Existing online noncooperative games rely on the sublinear growth of the path-length of Nash equilibrium sequences when considering dynamic regrets, which implies that their cost functions cannot be rapidly time-varying. Moreover, most of related results depend on undirected communication graphs. However, in many engineering practices, the cost functions may change greatly over time and the communication graphs may be directed. Here our problem involves rapidly time-varying cost functions, i.e., the path-length of Nash equilibrium sequences at least linearly grows, and the interaction topologies are unbalanced digraphs. In order to make decisions online without regrets, we develop a distributed algorithm based on multi-step mirror descents. Under the algorithm, sublinear dynamic regret bounds are established. More importantly, the dynamic regrets are independent of the path-length of Nash equilibrium sequences, compared with existing results. Finally, the simulation results validate the effectiveness of our algorithm, and demonstrate that our algorithm has better performance than other related algorithms.</div></div>","PeriodicalId":55413,"journal":{"name":"Automatica","volume":"175 ","pages":"Article 112200"},"PeriodicalIF":4.8,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143387822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We assume that the unknown parameter vector lies in a convex compact set such that the high-frequency gain matrix remains invertible for any parameter vector value in the set. These assumptions allow for a successful design of a robust model reference adaptive controller. A numerical example is included to fully illustrate the controller design and the effectiveness of the controller. As compared with the recent paper Pan and Başar (2023), the problem with uniform vector relative degree of zero allows us to relieve the block diagonally identical backbone structure for the measurement channels, choose a general quadratic cost structure that weighs the tracking errors arbitrarily, and achieve optimality for the control design.</div></div>","PeriodicalId":55413,"journal":{"name":"Automatica","volume":"175 ","pages":"Article 112190"},"PeriodicalIF":4.8,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143349006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 objective is to ensure that the vehicles attain a predetermined geometric configuration while simultaneously tracking a dynamic virtual leader in the presence of unexpected actuator faults. A novel distributed model predictive control (MPC) framework is proposed, where each UAV is equipped with an individual controller that adopts a hierarchical architecture comprising three sequentially connected control layers. The outer layer, integrating the Lyapunov-based MPC method with an adaptive parameter estimator, determines translation tracking control actions. The intermediate layer enforces the convergence of actual rotation angles toward the desired ones determined by the outer layer. The inner layer generates the torque control commands for rapid convergence of the angular velocities. The closed-loop stability of the entire multi-UAV system is rigorously analyzed, and sufficient conditions regarding the selection of user-defined parameters are established.

Rather than insisting on a strictly monotonic decrease of the Lyapunov function for the closed-loop system, P-ETC allows the Lyapunov function to increase as long as it remains below an acceptable performance-barrier. This approach integrates a performance residual—the difference between the value of the performance-barrier and the Lyapunov function—into the triggering mechanism. The integration adds flexibility and results in fewer control updates than with <em>regular</em> ETC (R-ETC) that demands a monotonic decrease of the Lyapunov function. Our P-ETC PDE backstepping design ensures global exponential convergence of the closed-loop system solution to zero in the spatial <span><math><msup><mrow><mi>L</mi></mrow><mrow><mn>2</mn></mrow></msup></math></span> norm, without encountering Zeno phenomenon. To avoid continuous monitoring of the triggering function that generates events, we develop periodic event-triggered and self-triggered variants (P-PETC and P-STC, respectively) of the P-ETC. The P-PETC only requires periodic evaluation of the triggering function whereas the P-STC preemptively computes the time of the next event at the current event time using the system model and continuously available system states. The P-PETC and P-STC also ensure a Zeno-free behavior and deliver performance equivalent to that of the continuous-time P-ETC which requires continuous evaluation of the triggering function, in addition to the continuous sensing of the state. We provide numerical simulations to illustrate the proposed technique and to compare it with R-ETC associated with strictly decreasing Lyapunov functions.</div></div>","PeriodicalId":55413,"journal":{"name":"Automatica","volume":"174 ","pages":"Article 112181"},"PeriodicalIF":4.8,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143192945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
