The interaction of output quantization and input quantization may lead to the nested quantizations, which complicates the system design immensely. Moreover, only by the plant output or the controller output received by their quantizers, the quantizers can not decide the dynamics of quantization region of the plant output and the controller output under packet erasure forward and backward channels, so some dynamical systems are constructed to represent the dynamics of quantization region for quantizing the outputs of the system and the controller. Specially, the state vector of the dynamical systems composes of not only the real outputs of the system and the controller but also their quantized values at last time. By these dynamical systems the considered system is modeled by a stochastic difference system, and the considered problem is transformed into the almost sure stability problem of the stochastic difference system.

For uncertain linear systems, a computationally inexpensive control method is the model reference adaptive control (MRAC). Although MRAC controllers come with strong stability guarantees they do not guarantee system operation within the pre-defined state and input constraints. Several modifications of the MRAC framework have been proposed to address input constraints in uncertain linear systems. Considering the infeasibility of arbitrary reference trajectories, reference modification has been implemented in the case of input constraints in the literature. The resulting conditions on the reference and input signals are difficult to verify online. Similar results on state and input constraints together have also been proposed, albeit resulting in more complex and unverifiable conditions on the control. In this paper, we have developed a modified MRAC controller that can handle state and input constraints in uncertain linear systems. We have also provided easily verifiable conditions on the control and reference under which our stability results hold. Obtaining such a verifiable condition is crucial in practical implementations on safety–critical systems. A combination of reference modification and barrier Lyapunov methods in adaptive control are employed to arrive at these results.</div></div>","PeriodicalId":50489,"journal":{"name":"European Journal of Control","volume":"82 ","pages":"Article 101196"},"PeriodicalIF":2.5,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143182570","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}

Subsequently, an integral sliding mode controller (ISMC) is incorporated to compensate for matching disturbances initially excluded from the model, and a super-twisting observer (STO) is employed to estimate and reject disturbances affecting the mechanical dynamics. The proposed control strategy enforces the convergence of two invariant manifolds to the origin. The first manifold ensures the asymptotic convergence of the position-tracking error to zero, while the second stabilizes the magnetic system and prevents magnetic flux saturation and singularities.

The distributed formation tracking error is then determined by applying the graph theory. Also, a mapping function is implemented to convert the constrained errors into new unconstrained variables as to achieve the prescribed performance. Second, the control law is formulated utilizing the finite time backstepping approach and event-triggering conditions, where the finite-time filter is adopted to reduce computational complexity. An adaptive strategy is developed to deal with model uncertainties and external disturbances using the universal approximation ability of radial basis function neural networks (RBFNNs). This strategy permits updating only two parameters per follower. The problem of control input saturation is also considered and resolved with the design of the finite-time auxiliary system. Consequently, all signals of the closed-loop system exhibit stability and achieve finite-time convergence while successfully avoiding the Zeno behavior.
