摘要:Security issues have gathered growing interest within the control systems community, as physical components and communication networks are increasingly vulnerable to cyber attacks. In this context, recent literature has studied increasingly sophisticated false data injection attacks, with the aim to design mitigative measures that improve the systems' security. Notably, data-driven attack strategies-whereby the system dynamics is oblivious to the adversary-have received increasing attention. H...

摘要:This article considers the data-driven stabilization of linear boundary controlled parabolic PDEs by making use of the Koopman operator. For this, a Koopman eigenstructure assignment problem is solved, which amounts to determining a feedback of the Koopman open-loop eigenfunctionals assigning a desired finite set of closed-loop Koopman eigenvalues and eigenfunctionals to the closed-loop system. It is shown that the designed controller only needs a finite number of open-loop Koopman eigenvalues...

摘要:In this article, we study the problem of decentralized optimization in the presence of adversarial attacks. In this problem, we consider a collection of nodes connected through a network, each equipped with a local function. These nodes are asked to collaboratively compute the global optimizer, i.e., the point that minimizes the aggregated local functions, using their local information and messages exchanged with their neighbors. Moreover, each node should agree on the said minimizer despite a...

摘要:We consider the design of event-triggered distributed controllers for multi-agent systems that are digitally implemented on local computation platforms and communicate over a packet-based network. Each agent is equipped with a local triggering mechanism that is only evaluated at the local sampling instants, thereby, taking a periodic event-triggered approach in which the sampling intervals are allowed to vary (jitter). Moreover, the locally triggered transmissions are subject to unknown, bound...

摘要:This article considers the problem to estimate a graphical model corresponding to an autoregressive moving-average (ARMA) Gaussian stochastic process. We propose a new maximum entropy covariance and cepstral extension problem and we show that the problem admits an approximate solution, which represents an ARMA graphical model whose topology is determined by the selected entries of the covariance lags considered in the extension problem. Then, we show how the corresponding dual problem is conne...

摘要:In this article, we develop a systematic method for constructing a generalized discrete-time control Lyapunov function for the flexible-step model predictive control (MPC) scheme, recently introduced in (F & uuml;rnsinn et al., 2025), when restricted to the class of linear systems. Specifically, we show that a set of linear matrix inequalities (LMIs) can be used for this purpose, demonstrating its tractability. The main consequence of this LMI formulation is that, when combined with flexible-s...

摘要:This technical note is concerned with boundary stabilization of multidimensional discrete-velocity kinetic models. By exploiting a certain stability structure of the models and adapting an appropriate Lyapunov functional, we derive feasible control laws so that the corresponding solutions decay exponentially in time. The result is illustrated with an application to the 2-D coplanar model in a square container. The effectiveness of the derived control laws is confirmed by numerical simulations.

摘要:This article addresses the multigroup consensus problem with signed networks, where a set of agents with positive-weight edges is treated as a group, and the edges among groups are negative weights. Based on group homomorphism theory, each group can be mapped as a virtual node, called the group representative node. Consequently, the signed networks can be represented by the homomorphic mapping graph with only negative weight edges. The definition of structural balance has been extended, elimin...

摘要:In this article, we investigate the optimal control problem for an unknown linear time-invariant system. To solve this problem, a novel composite policy iteration algorithm based on adaptive dynamic programming is developed to adaptively learn the optimal control policy from system data. The existing methods require the initial stabilizing control policy, the persistence of excitation (PE) condition and the data storage to ensure the algorithm convergence. Fundamentally different from them, th...
