摘要：This article deals with the stabilization of a class of linear infinite-dimensional systems with unbounded control operators and subject to a boundary disturbance. We assume that there exists a linear feedback law that makes the origin of the closed-loop system globally asymptotically stable in the absence of disturbance. To achieve our objective, we follow a sliding mode strategy, and we add another term to this controller in order to reject the disturbance. We prove the existence of solution...

摘要：The problem of the distributed Nash equilibrium (NE) seeking for aggregative games has been studied over strongly connected and weight-balanced static networks and every time strongly connected and weight-balanced switching networks. In this article, we further study the same problem over jointly connected and weight-balanced networks. The existing approaches critically rely on the connectedness of the network and these approaches fail if the network is not connected. To overcome this difficul...

摘要：Achieving global input-to-state stability (ISS) in closed-loop systems becomes a challenging task when integrating an adaptive scheme into control design. This challenge is particularly prominent in the global output regulation of nonlinear systems. The current state of the art in global robust adaptive output regulators is limited to achieving a weaker form of integral-ISS. In this article, we present an ISS-based design framework for a class of nonlinear systems with input perturbation via a...

摘要：The aim of this article is to design static output feedback controllers for multi-input-multi-output (MIMO) linear time-invariant (LTI) systems, with the requirements of positivity and asymptotic stability to be guaranteed in closed-loop systems. By expressing the matrix product $KC$ as a sum of rank one matrices, new necessary and sufficient conditions for the existence of a static output feedback controller are derived in terms of linear programming (LP) conditions. One of the advantages of ...

摘要：In the conventional framework for distributed fault prognosis of discrete-event systems (DESs), it is assumed that observable events are always observed [such case is called static event observations (SEOs)]. However, the assumption may not hold in many DESs such as sensor networks. This article introduces the concept of distributed fault prognosis with dynamic event observations (DEOs), in which observable events are not always observed. Communication models and extended models are constructe...

摘要：We consider a generic decentralized constrained optimization problem over static, directed communication networks, where each agent has exclusive access to only one convex, differentiable, local objective term and one convex constraint set. For this setup, we propose a novel decentralized algorithm, called double averaging and gradient projection (DAGP). We achieve global optimality through a novel distributed tracking technique we call distributed null projection. Further, we show that DAGP c...

摘要：Though historically regarded as unrelated concepts, passivity-based control (PBC) and control barrier functions (CBFs) are methods used to establish the safety of control systems. In this article, an optimization-based PBC technique is developed which can be combined with CBF-based methods to find a set of controllers that each render a nonlinear control system energetically passive while also adhering to state constraints necessary for safety. Borrowing concepts from literature developed for ...

摘要：This article addresses the sampled-data boundary stabilization of 2-D semilinear parabolic stochastic partial differential equation (PDEs) with globally Lipschitz nonlinearities. We consider Dirichlet actuation and design a finite-dimensional state-feedback controller with the shape functions in the form of eigenfunctions corresponding to the first N comparatively unstable eigenvalues. We extend the trigonometric change of variables to the 2-D case and further improve it, leading to a dynamic ...

摘要：Distributed online learning has been proven extremely effective in solving large-scale machine learning problems over streaming data. However, information sharing between learners in distributed learning also raises concerns about the potential leakage of individual learners' sensitive data. To mitigate this risk, differential privacy, which is widely regarded as the gold standard for privacy protection, has been widely employed in many existing results on distributed online learning. However,...

摘要：We present a new practical stability analysis for a bounded gradient based extremum seeking problem for two variable static quadratic maps that contain a time-varying additive measurement uncertainty. Instead of using earlier averaging-based approaches, we introduce a new state transformation, a time-varying quadratic Lyapunov function, and a comparison principle to obtain essentially less conservative bounds on the dither frequency and on the ultimate bound of the estimation error compared wi...
