摘要：This article studies the Nash equilibrium (NE) seeking problem for multiple coalition games over unbalanced directed graphs, where the players in the same coalition aim to achieve the optimal consensus cooperatively, but different coalitions competitively seek the NE. A distributed algorithm is proposed based on the coalition estimate strategy (CES) and the gradient tracking method. The CES directly estimates the consensus decision in a coalition rather than all decisions of other players, and...

摘要：In this article, a robust data-driven moving horizon estimation (MHE) scheme for linear time-invariant discrete-time systems is introduced. The scheme solely relies on offline collected data without employing any system identification step. We prove practical robust exponential stability for the setting where both the online measurements and the offline collected data are corrupted by nonvanishing and bounded noise. The behavior of the novel robust data-driven MHE scheme is illustrated by mean...

摘要：We introduce an online convex optimization algorithm which utilizes projected subgradient descent with optimal adaptive learning rates. We provide a second-order minimax-optimal dynamic regret guarantee (i.e., dependent on the sum of squared subgradient norms) for a sequence of general convex functions, which may not have strong-convexity, smoothness, exp-concavity or even proper Lipschitz-continuity. The guarantee holds against any comparator sequence with bounded path variation (i.e., the su...

摘要：Complex systems are often composed of many small communicating components called modules. We investigate the synthesis of supervisory controllers for modular systems under partial observation that, as the closed-loop system, realize the supremal normal sublanguage of the specification. Such controllers are called maximally permissive normal supervisors. The challenge in modular systems is to find conditions under which the global nonblocking and maximally permissive normal supervisor can be ac...

摘要：This article investigates the distributed fixed-point finding problem for a global operator over a directed and unbalanced multiagent network, where the global operator is quasi-nonexpansive and only partially accessible to each individual agent. Two cases are addressed, i.e., the global operator is sum separable and block separable. For this first case, the global operator is the sum of local operators, which are assumed to be Lipschitz, and each local operator is privately known to each indi...

摘要：Optimization problems emerging in most of the real-world applications are dynamic, where either the objective function or the constraints change continuously over time. This article proposes projected primal-dual dynamical system approaches to track the primal and dual optimizer trajectories of an inequality constrained time-varying (TV) convex optimization problem with a strongly convex objective function. First, we present a dynamical system that asymptotically tracks the optimizer trajector...

摘要：In this article, we consider the finite horizon filtering problem of discrete-time Markov jump systems (MJS). In the first part, we consider an MJS satisfying some general nonlinear conditions. It is obtained, for a fixed set of auxiliary constants, filter gains, based on a set of coupled Riccati-like difference equations, that yield a minimum upper bound for the estimation error covariance matrix. When the nonlinear parameters are set to zero, the MJS becomes a Markov jump linear system (MJLS...

摘要：This work deals with the distributed Byzantine-resilient observer (DBRO) design problem for continuous-time high-order integrator multiagent systems on directed graphs, which intends to estimate the leader states accurately in a finite-time interval. A new kind of edge-based DBRO is first formulated for the followers to estimate each order of the nonautonomous leader's state, which is implemented in a cascading manner. Then, the finite-time zero-error estimation performance of the above DBRO i...

摘要：This article presents a dynamic model of multiple self-propelled particles with a periodic controller inspired by the intermittent locomotive behavior in various fish species. The closed-loop dynamics are split into a burst phase during which each particle applies a control input and a coast phase during which each particle performs state estimation. This model allows us to investigate how having nonoverlapping sensing and control affects a system's ability to achieve collective behavior such ...

摘要：This article proposes several criteria for the distribution of roots of quasi-polynomials of neutral type with complex coefficients. Compared with Pontryagin's results, the derived criteria can be numerically implemented because the interval of the frequency for analyzing the behavior of the quasi-polynomial can be determined. Moreover, some Hurwitz stability criteria to judge whether all the roots of the quasi-polynomials are in the open left-half complex plane are provided. These Hurwitz sta...
