摘要：This article investigates the differentially private bipartite consensus problem over signed networks. To solve this problem, a new algorithm is proposed by adding noises with time-varying variances to the cooperative-competitive interactive information. In order to achieve the privacy protection, the variances of the added noises are allowed to increase, which are substantially different from the existing works. In addition, the variances of the added noises can be either decaying or constant...

摘要：In this article, we study the problem of the distributed Nash equilibrium seeking of $N$-player games over jointly strongly connected switching networks. The action of each player is governed by a class of uncertain nonlinear systems. Our approach integrates the consensus algorithm, the distributed estimator over jointly strongly connected switching networks, and some adaptive control techniques. Furthermore, we also consider the disturbance rejection problem for bounded disturbances with unkn...

摘要：A simple fixed-time converging estimation algorithm is presented for a linear regression using the dynamic regressor extension and mixing method within a discrete-time setting, with a persistently excited regressor and bounded measurement noises. The solution is based on Kreisselmeier's filters, and it is computationally simpler than the existing analogs.

摘要：To appropriately select control nodes in a large-scale network system, we propose two control centralities called volumetric and average energy controllability scores. The scores are the unique solutions to convex optimization problems formulated using the controllability Gramian. The uniqueness is proven for stable cases and for unstable cases that include multiagent systems. We show that the scores can be efficiently calculated by using a proposed algorithm based on the projected gradient me...

摘要：In this article, we present necessary and sufficient conditions under which a linear time-invariant (LTI) system is state feedback equivalent to a negative imaginary (NI) system. More precisely, we show that a minimal LTI strictly proper system can be rendered NI using full state feedback, if and only if it can be output transformed into a system, which has relative degree less than or equal to two and is weakly minimum phase. We also considered the problems of state feedback equivalence to ou...

摘要：This article develops an approach to achieving consensus while improving the dynamic performance for a class of homogeneous multi-agent systems (MASs) using delayed state information via eigenvalue assignment. Note that the distribution of roots of quasi-polynomials plays a fundamental role in the consensus protocol design of the MASs. Some necessary conditions for the distribution of roots for a class of quasi-polynomials are first derived. Then, these conditions are applied to estimate the a...

摘要：This article provides novel results on the infinite-horizon linear quadratic tracking (LQT) problem for continuous-time systems. In order to fulfill optimality for the tracker design, we introduce a new performance index to reformulate the LQT problem in terms of the minimal polynomial of the exosystem that generates the reference trajectory. We prove that, under routine assumptions, the obtained solution to the formulated LQT problem realizes both closed-loop stability and asymptotic tracking...

摘要：In this article, we propose a second-order extension of the continuous-time game-theoretic mirror descent (MD) dynamics, referred to as MD2, which provably converges to mere (but not necessarily strict) variationally stable states (VSS) without using common auxiliary techniques, such as time-averaging or discounting. We show that MD2 enjoys no-regret as well as an exponential rate of convergence toward strong VSS upon a slight modification. MD2 can also be used to derive many novel continuous-...

摘要：This article studies the linear-quadratic optimal control of linear systems with jump parameters driven by a Markov chain in reverse-time, anticipative observation of the jump variable, and exogenous inputs. This type of problem appears, for example, when a system with Markov jumps interacts with a first-in last-out queue, as illustrated in different contexts in this article. The solution is given in terms of precomputable, coupled Riccati equations, and the number of variables depends on the ...

摘要：In this article, we study the cooperative dynamic coverage control problem by using viability theory. We focus on the intertemporal coverage optimization for nonlinear mobile sensor networks with mobility constraint, arbitrary sensory range, and obstacle avoidance over large-scale domains, which remains to be an interesting open problem prior to this work. Our proposed cooperative coverage control law enables the constrained sensor networks to minimize the overall intertemporal cost of the dis...
