摘要:This article proposes an iterative distributed model predictive control (DMPC) approach for discrete-time linear systems with decoupled and coupled constraints over undirected communication networks. To address the coupled constraint, we transform a DMPC optimization problem into its dual problem. Then, a novel event-triggered distributed dual averaging (ETDDA) algorithm is designed to solve this dual problem, in which event-triggered mechanisms can tremendously save communication resources. W...

摘要:In this article, we study the problem of resilient average consensus (RAC) in multiagent systems where some of the agents are subject to failures or attacks. The objective of RAC is for nonfaulty/normal agents to converge to the average of their initial values despite the erroneous effects from malicious agents. To this end, we propose a successful distributed iterative RAC algorithm for the multiagent networks with general directed topologies. The proposed algorithm has two parts at each iter...

摘要:This article is concerned with distributed dynamic event-triggered Nash equilibrium seeking in merely monotone games under switching communication topologies. Based on a regularization algorithm, a gradient play and a leader-following consensus protocol, a distributed Nash equilibrium seeking strategy incorporating an event- and switching-activated communication scheme is established. More specifically, the regularization algorithm is involved to compensate for the absence of strict/strong mon...

摘要:this article, we develop a method to compute ellipsoidal maximal tolerable fault (e-MTF) sets of robust model predictive control (MPC) for passive fault tolerance. The maximal tolerable fault set serves as an index to evaluate the passive fault- tolerance capabilities of robust MPC frameworks. In particular, a regulation problem for a discrete-time linear time-invariant system with an additive fault model is considered. We construct convex optimization problems to compute the e-MTF sets for th...

摘要:Existing function augmented sliding mode control approaches based on preset trajectories are applicable only to matched uncertain systems. In this article, two preset-trajectory-based tracking control methods are proposed for a class of mismatched uncertain systems utilizing the backstepping method. The first method is the preset-trajectory-based practical prescribed-time tracking control method, which can guarantee that the output tracking error converges to a prescribed zone in a prescribed ...

摘要:Critical questions in dynamical neuroscience and machine learning are related to the study of continuous-time neural networks and their stability, robustness, and computational efficiency. These properties can be simultaneously established via a contraction analysis. This article develops a comprehensive non-Euclidean contraction theory for continuous-time neural networks. Specifically, we provide novel sufficient conditions for the contractivity of general classes of continuous-time neural ne...

摘要:This article proposes and verifies two types of state-based timed opacity notions for constant-time labeled automata (a class of timed models with partially observable transitions), called [T-l,T-u]-opacity and [T-l,+infinity)-opacity . A system is said to be [T-l,T-u]-opaque (respectively, [T-l,+infinity)-opaque ) if no timed observation can lead to the exposure of specified states (called secret states ) within a finite time window (respectively, an infinite time window) starting at the time...

摘要:This article proposes a distributed algorithm for average consensus in a multiagent system under a fixed bidirectional communication topology, in the presence of untrustworthy (malicious) agents (nodes) that may try to influence the average consensus outcome by manipulating their updates. The proposed algorithm converges asymptotically to the average of the initial values of the trustworthy (nonmalicious) nodes, which we refer to as the trustworthy average, as long as the underlying topology t...

摘要:In this article, we extend discrete-time explicit model-predictive control (MPC) rigorously to linear distributed parameter systems. After formulating an MPC framework and giving a relevant Karush-Kuhn-Tucker theorem, we realize fast regionless explicit MPC by using the dual-active-set method QPKWIK. A Timoshenko beam with input and state constraints is used to demonstrate the efficacy of the design at controlling a continuous-time hyperbolic partial differential equation with constraints, usi...
