Secondly, the Lyapunov–Krasovskii functions(LKFs) with state information of time delay are constructed, whose goal is to capture more dynamics of time delay that impact on the controller’s design. And a group of sufficient conditions in the aspect of linear matrix inequalities(LMIs) is derived to guarantee that the states of error system can be confined within a finite union of ellipsoid-like sets corresponding to each mode with consensus manifestation under the action of switching topology randomly governed by SMST-PUR. Simultaneously, the method of co-designing the consensus controller and the triggered matrices of ETS with RSE performance is depicted to save communication resources availably.

Identifying the system’s parameters and these switching instants from potentially noisy measurements of the system’s states is a relevant problem in several applications. We here propose a novel approach for estimating the time-varying parameters of a broad class of nonlinear dynamical systems from noisy state measurements. We formulate the problem as a mixed-integer quadratic program (MIQP) including a sparsity constraint to enforce the piecewise constant nature of the parameters. Then, we develop a convex relaxation of the problem in the form of a quadratic program (QP). The solution of the relaxed convex QP and/or the sub-optimal solutions of the MIQP returned by the MIQP solvers provide us with computationally-efficient approximations that can be used effectively in those large-dimensional cases in which the solution of the original MIQP is difficult to obtain. After validating our approach in a controlled experiment, we demonstrate its potential on two real-world case studies regarding marketing and epidemiological applications.</div></div>","PeriodicalId":50489,"journal":{"name":"European Journal of Control","volume":"81 ","pages":"Article 101151"},"PeriodicalIF":2.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143102188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to deal with these limitations, an observer-based adaptive backstepping torque–position control approach is proposed in this paper. In order to achieve this objective, a novel external torque observer is proposed to alleviate the limitations associated with the use of force sensors. This paper’s main idea is to employ a three-channel architecture using a force sensor-less reflecting signal, which can improve transparency and increase algorithm performance. Furthermore, the another point of this paper is to enhance the safeness of operations in the presence of time-varying delays in the communication channel, a position error constraint control strategy is employed in the core of the proposed approach. Moreover, the primary advantage of this paper is that, the proposed observer-based control algorithm is relieved from the joints acceleration measurement of the leader and follower manipulators which is difficult in robotic systems.

The issue of initialization of real-order control system enhancement remains a challenging issue in the systems analysis subject to random initial-time placed on a real number line. We address a new design of a class of real-order control systems that consists of separated linear and nonlinear terms affected by input functions to be controlled with an implemented time-varying linear state feedback controller. We utilize the fractional comparison method and under Lipschitz nonlinearity with a constant bounding matrix of time-varying coefficients of control systems to address new order-dependent conditions that provide local and global stabilization to controlled systems. Applications of results that include practical real-order single-machine-infinite-bus power systems have been illustrated to control the responses by the utility of theoretical conditions examined along with validation of numerical simulations.
