摘要：In this article, we address the problem of exponential mean-square stabilization control for cyber-physical systems (CPSs) characterized by time-varying parameters, random denial-of-service (DoS) attacks, and transmission delay. The motivation arises from the increasing complexity and vulnerability of CPSs, which are prone to various networked challenges, including random DoS attacks and transmission delays. In addition, the presence of time-varying parameters further exacerbates the difficult...

摘要：We study control of constrained linear systems with only partial statistical information about the uncertainty affecting the system dynamics and the sensor measurements. Specifically, given a finite collection of disturbance realizations drawn from a generic distribution, we consider the problem of designing a stabilizing control policy with provable safety and performance guarantees despite the mismatch between the empirical and true distributions. We capture this discrepancy using Wasserstei...

摘要：We investigate decentralized state estimation for a discrete event system in a setting where the information received at a coordinator may be corrupted or tampered by a malicious attacker. Specifically, a system is observed by a set of (local) observation sites (OSs) which occasionally send their recorded sequences of observations to the coordinator that is in charge of estimating the system state. The malfunctions and attacks, referred to as errors in this article, include symbol deletions, i...

摘要：This article proposes a new approach that enables multiagent systems to achieve resilient constrained consensus in the presence of Byzantine attacks, in contrast to existing literature that is only applicable to unconstrained resilient consensus problems. The key enabler for our approach is a new device called a (gamma(i), alpha(i))-Resilient Convex Combination, which allows normal agents in the network to utilize their locally available information to automatically isolate the impact of the B...

摘要：We study the decentralized online regularized linear regression algorithm over random time-varying graphs. At each time step, every node runs an online estimation algorithm consisting of an innovation term processing its own new measurement, a consensus term taking a weighted sum of estimations of its own and its neighbors with additive and multiplicative communication noises and a regularization term preventing over-fitting. It is not required that the regression matrices and graphs satisfy s...

摘要：This article is concerned with the problem of safety control for switched systems, where different safe sets are allowed for different subsystems and safety is not necessarily possessed for subsystems. A necessary and sufficient condition is presented for safety of switched systems by exploiting a multiple barrier functions (MBFs) method. To reveal the relationship about safety between subsystems and switched systems, an extended Nagumo's Theorem in the switched systems framework is derived. A...

摘要：This note focuses on the issue of whether or not the state of a plant can be estimated when the inputs of communication channel involve noise and disturbance simultaneously. It turns out to calculate the maximum capacity of stationary memoryless M-MQAC under nonstochastic information theory. It is shown that the maximum information rate over such a channel is determined by a convex hull spanned by the zero-error capacities, which are specified on the underlying sample spaces. Moreover, the sta...

摘要：A recent theoretical analysis of a Monte-Carlo tree search (MCTS) method properly modified from the upper confidence bound applied to trees (UCT) algorithm established a surprising result, due to a great deal of empirical successes reported from heuristic usage of UCT with relevant adjustments for various problem domains in the literature, that its rate of convergence of the expected absolute error to zero is O(1/root n) in estimating the optimal value at an initial state in a finite-horizon M...

摘要：This article studies a decentralized homogeneous multiarmed bandit problem in a multiagent network. The problem is simultaneously solved by N agents assuming that they face a common set of M arms and share the same arms' reward distributions. Each agent can receive information only from its neighbors, where the neighbor relationships among the agents are described by a fixed graph. Two fully decentralized upper confidence bound (UCB) algorithms are proposed for undirected graphs, respectively,...

摘要：Preserving the topology from being inferred by external adversaries has become a paramount security issue for network systems, and adding random noises to the nodal states provides a promising way. Nevertheless, recent works have revealed that the topology cannot be preserved under independent identically distributed (i.i.d.) noises in the asymptotic sense. How to effectively characterize the nonasymptotic preservation performance still remains an open issue. Inspired by the deviation quantifi...
