Functions whose minimizer vector exhibits a constant component within the kernel space of the constraint horizontal matrix are considered. By resorting to the latest developments in the repetitive control (RC) theory, two algorithms are originally presented: the first one resorting to the point-wise use of the delay as a universal periodic signal generator, the second one relying on the PDE (Partial Differential Equation) transport-equation-based theory. Both of them naturally extend the standard primal–dual algorithm acting in the constant constraint scenario, while guaranteeing global asymptotic convergence properties. Indeed, the two main different RC approaches in the literature are applied to the same optimization problem, while drawing original conclusions under the adoption of a common view. The derivation of an internal-model-based finite-dimensional (spectral) approximation for the latter introduces a further interpretation of the renowned adaptive learning control.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"201 ","pages":"Article 106095"},"PeriodicalIF":2.1,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143838983","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 system under investigation is remarkably characterized by the unknown nonlinear terms involved in the boundary actuator which are not necessarily linearly grow or parameterized by unknown constants, and hence imply more serious uncertainties and nonlinearities than those of the related literature. Such a feature results into the incapability of the traditional schemes on this topic and then deserves a powerful one for the investigated control problem. For this, a novel adaptive control method is proposed by combining the infinite- and finite-dimensional backstepping method with the adaptive dynamic compensation technique, which brings an explicit state-feedback controller. Particularly, by a smart redefinition of the unknown parameter and the introduction of certain tuning functions, only one dynamic compensator is needed for the compensation of the serious uncertainties, and hence removes the overparametrization in the related literature. A rigorous proof procedure shows the boundedness of the signals of the resulting closed-loop system and the convergence of the original system states, together with the exclusion of the Zeno phenomenon. Finally, a simulation example is provided to validate the effectiveness of the proposed theoretical results.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"201 ","pages":"Article 106098"},"PeriodicalIF":2.1,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143834945","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 objective of this paper is to design a small gain adaptive controller with state constraints in the presence of uncertain factors such as unknown covariance noise and interference. A property of tangent barrier function is investigated, so that barrier Lyapunov function can be novel imbedded into the small gain controller and there is no violation of the time-varying constraints in the stochastic setting. Meanwhile, it has provided a detailed explanation in the remarks regarding the relationship between the new properties and the differential homeomorphism transformation method. Under the framework of the backstepping method, the combination of changing supply function and the small gain approach is used to obtain the stochastic input-to-state practically stability Lyapunov function of the subsystem, overcoming the influence of unknown covariance noise, unknown dynamics, and unknown parameters.
