摘要:A new dynamic-scaling-based global adaptive quantized control approach is proposed for nonlinear systems with input and state quantization, which reduces some conservatism of relevant results, including matched nonlinearities, global Lipschitz continuity, and quantization error satisfying constant bound. A unique idea is used to deal with the quantized-state feedback problem, that is, the coefficient deviation problem in the decomposition of sector-bounded quantizer is converted to that of sol...

摘要:Control barrier functions (CBFs) enable constraint satisfaction in controlled dynamical systems, by mapping state constraints into state-dependent input constraints. This article investigates the use of hybrid CBF formulations for constraint satisfaction in continuous-time systems. Augmenting CBFs with logic variables enables solving control problems that are not solvable by continuous, or even discontinuous, control. Examples include robust deadlock resolution for vehicles moving in the prese...

摘要:The problem of controlling cooperative multiagent systems under different models of information sharing among agents has received significant attention in the recent literature. In this article, we consider a setup where rather than committing to a fixed and nonadaptive information sharing protocol (e.g., periodic sharing or no sharing, etc.), agents can dynamically decide at each time step whether to share information with each other and incur the resulting communication cost. This setup requ...

摘要:This note investigates the consensus of discrete-time multiagent systems, where the consensus error between neighboring agents is subject to transient performance constraints. The examination of transient performance constraints holds paramount importance in ensuring the secure and optimal functioning of real systems. Nevertheless, the existing body of research pertaining to constraints has predominantly focused on continuous-time systems, with limited attention given to discrete-time systems....

摘要:We consider a distributed personalized optimization problem over a network of nodes whose cost functions depend on a decision variable consisting of two parts: global (shared) part and local (node-specific) part. This problem structure arises in several important scenarios, where the global part captures the common feature among nodes and the local part represents the personalized feature. To solve this problem, we develop a flexible algorithmic framework employing personalized distributed sto...

摘要:Designing fast, distributed algorithms for multiagent problems is vital for many novel application domains. Greedy algorithms have been shown in many multiagent contexts to be an efficient approach to arrive at good solutions quickly. In this work, we ask the following: Is there any way to improve the performance of greedy algorithms without sacrificing the linear run-time guarantees? For this, we take inspiration from incentive design in the game-theoretic literature. In this work, we conside...

摘要:In this article, we study the problem of uniform local and global asymptotic stabilization of the origin for nonlinear discrete-time control systems with periodic coefficients via state feedback. It is assumed that the origin of the free dynamic system is Lyapunov stable. The approach is based on the Krasovsky-La Salle invariance principle for discrete-time periodic systems. The stabilizing control law is constructed by means of applying bounded feedback design technique previously developed f...

摘要:This article is concerned with consensus for heterogeneous multiagent systems under distributed nonlinear control protocol. Based on general Lyapunov functions beyond the quadratic form, a less conservative consensus criterion is proposed in the presence of only a directed spanning tree. Then, the consensus problem for polynomial systems can be converted into a sum-of-squares programming problem, yielding polynomial Lyapunov functions efficiently to realize the consensus criterion verification...

摘要:In this article, we study a data-driven control method for the robust output regulation problem. The method exploits the parameterization property of a system from the observed data that do not necessarily satisfy the persistently exciting condition for system identification. It is based on a data informativity theory, which infers a system property for designing a controller for a whole family of systems (including the true system) that can generate the same observed data. The new idea is to ...

摘要:In recent years, the synchronization problem of dynamical networks under adaptive intermittent control has been extensively studied, but it has not been well solved up to now. In this article, we further investigate this problem. The updating laws adopted here is simpler than that in much of the literature. First, boundedness of the adaptive control gain is proved to ensure practicality of adaptive control. Then, synchronization criteria for dynamical networks under adaptive intermittent contr...
