摘要:In this article, we consider a composite optimization problem with linear coupling constraints in a multiagent network. In this problem, the agents cooperatively optimize a strongly convex cost function, which is the linear sum of individual cost functions composed of smooth and possibly nonsmooth components. To solve this problem, we propose an asynchronous penalized proximal gradient (Asyn-PPG) algorithm, a variant of classical proximal gradient method, with the presence of the asynchronous ...

摘要:In this article, we present how to synthesize controllers to enforce omega-regular properties over linear control systems affected by bounded disturbances. In particular, these controllers are synthesized based on so-called hybrid controlled invariant (HCI) sets. To compute these sets, we first construct a product system between the linear control system and the deterministic Streett automata (DSA) modeling the desired property. Then, we propose a set-based approach, which exploits a new itera...

摘要:Investigating long-term behaviors of stochastic dynamical systems often requires to establish criteria that are able to describe delicate dynamics of the considered systems. In this article, we develop generalized invariance principles for continuous-time stochastic dynamical systems. Particularly, in a sense of probability one and by the developed semimartingale convergence theorem, we not only establish a local invariance principle, but also provide a generalized global invariance principle ...

摘要:The framework of port-Hamiltonian (pH) systems is a powerful and broadly applicable modeling paradigm. In this article, we extend the scope of pH systems to time-delay systems. Our definition of a delay pH system is motivated by investigating the Kalman-Yakubovich-Popov inequality on the corresponding infinite-dimensional operator equation. Moreover, we show that delay pH systems are passive and closed under interconnection. We describe an explicit way to construct a Lyapunov-Krasovskii functi...

摘要:The early results on the adaptive distributed observer for uncertain leader systems have three limitations. The adaptive distributed observer is state-based, the communications among the follower subsystems are undirected, and the communication network is static. Despite years of efforts, these issues have not been fully addressed. In this article, we develop an output-based adaptive distributed observer for a class of uncertain linear leader systems over jointly connected switching networks. ...

摘要:In this article, under limited communication resources, the sliding mode control problem is investigated for 2-D the second Fornasini-Marchesini systems with one finite-interval direction. A two-index-based event-triggered scheme is proposed to avert unnecessary signal transmissions from sensors to the controller. According to the finite-interval bound and the previous access node, a channel scheduling mechanism is established to periodically orchestrate the communication between controller an...

摘要:This article addresses the stability of switching between a uniformly ultimately bounded (UUB) system and an asymptotically stable system with asymptotically decaying perturbation using multiple Lyapunov functions. It is proven that the switched system trajectories remain UUB if an average dwell time condition is satisfied, and the perturbation terms are bounded with a sufficiently small magnitude. The developed switched system stability results are applied to the state estimation of the persp...

摘要:In this article, we address the event-triggered consensus problem for single-integrator multiagent systems by introducing a novel nonlinear control protocol. With the proposed consensus protocol, convergence with prescribed transient performance of the closed-loop system can be guaranteed while control execution is triggered by a delicately designed edge-based event-triggering mechanism. The protocol also ensures that no agent exhibits Zeno behavior. Moreover, the method can be extended to the...

摘要:In this article, we consider a cooperative control problem involving a heterogeneous network of dynamically decoupled continuous-time linear plants. The (output-feedback) controllers for each plant may communicate with each other according to a fixed and known transitively closed directed graph. Each transmission incurs a fixed and known time delay. We provide an explicit closed-form expression for the optimal decentralized controller and its associated cost under these communication constrain...

摘要:This article addresses the topic of event-triggered output feedback stabilization of reaction-diffusion partial differential equations (PDEs). The control applies at the boundary while the output is distributed. The control strategy consists of a finite-dimensional controller augmented with an adequate event-triggered mechanism. This event-triggered mechanism dictates the time instants at which the applied control input needs to be updated based on the occurrence of specific events monitored b...
