摘要 ：
This article proposes a novel framework for studying the consensus problem for a class of nonlinear multiagent systems (MASs) based on decentralized output-feedback stabilization of derived reduced-order fundamental edge states dynamic systems. First, by introducing edge states dynamics with respect to a directed spanning tree of the communication topology, we equivalently transform the state consensus problem into a decentralized output feedback stabilization problem. Then, for the case of linear MASs, we derive a new sufficient and necessary consensus criterion in terms of the concept of decentralized fixed modes and also present a design procedure of the protocol gains in terms of linear matrix inequalities (LMIs). Next, a sufficient consensus condition is derived in terms of LMIs for the nonlinear MAS with local proportional-integral (PI) observers. Furthermore, to reduce the complexity of the condition verification, we introduce a graph representation of the fundamental edge states dynamic system and decompose it into strongly connected components and, thus, reorganize the condition in a decentralized form. On this basis, we present a hierarchical method to design the consensus protocols and PI observers based on the information of the subsystem itself only. Finally, several numerical examples are given to illustrate the effectiveness of the proposed method.

摘要 ：
Accurate traffic estimation on urban networks is a prerequisite for efficient traffic detection, congestion warning, and transportation schedule. The current estimation methods can be roughly divided into model-driven and the data-driven methods. The estimation accuracy of the model-driven methods cannot satisfy certain applications. Meanwhile, the data-driven methods have the disadvantages of poor generalization ability and weak interpretability. To overcome these challenges, this paper proposes a framework named the physics-informed spatiotemporal graph convolution neural network (PSTGCN) based on physics-informed deep learning theories. The PSTGCN uses a spatiotemporal graph convolution neural network combined with traffic flow models to estimate the traffic state. The proposed model not only considers the temporal and spatial dependence of traffic flow but also abides by the internal law of traffic flow. Furthermore, the estimation objects of the proposed model are multiple variables that comprehensively represent the traffic state. Experiments on real-world traffic data reveal the error of the PSTGCN is reduced by 38.39% compared to the baselines. Also, the PSTGCN can achieve a similar prediction effect as the baselines by using half of the global spatial information. These results demonstrate that the PSTGCN outperforms the state-of-the-art models in urban traffic estimation and is robust under variable road conditions and data scales.

摘要 ：
This paper focuses on the problem of distributed fault detection and leader-following output consensus for heterogeneous multiagent systems subject to deception attacks. During the information exchange and dissemination, a malicious attacker can make full use of specialized computer technology and launch stochastic deception attacks against some vulnerable agents over the network. The attack signals in actual operation tend to be energy-constrained, and Bernoulli distribution can be used to describe the random features. Taking the attack information into account, the distributed fault detection observer and the dynamic consensus compensator are designed in two separate steps. In order to reduce unnecessary information transmission, a dynamic event-triggered mechanism with output-dependent threshold is introduced to the adjustment of consensus protocol. According to Lyapunov stability theory and linear matrix inequality (LMI) techniques, sufficient conditions are derived for developing the model gains of the observer and the compensator. Finally, a simulation example of RLC circuit systems is provided to illustrate the effectiveness of the obtained theoretical results.

摘要 ：
This paper considers the problem of leader-following consensus and fault detection for a class of multi-agent systems with Lipschitz nonlinear dynamics. To reduce the amount of redundant information and avoid checking triggering conditions continually, this paper proposes an efficient network framework with a double periodic event-triggered mechanism. Based on the proposed framework, an improved fault detection observer and a consensus controller are designed. Then, the original problem is converted into a set of stability problems with constraints. According to Lyapunov-Krasovskii theorem and the free-weighting matrix technique, sufficient conditions for solving these stability problems are derived in the form of bilinear matrix inequalities (BMIs). Further, to eliminate the nonlinear terms of BMI and obtain optimal performance, two iterative algorithms based on linear matrix inequalities (LMIs) are developed. Two simulation examples are provided to verify the practicality and validity of the theoretical results.

摘要 ：
In this paper, periodic event-triggered leaderless and leader-following consensus problems are studied for linear multi-agent systems with deterministic packet losses under the generic directed communication topology. Specially, an event-triggered mechanism is proposed, which only needs to communicate the event-triggered states of the agent and verify the event-triggered condition at the periodic sampling instants. A switched system with stable and unstable subsystems is used to describe packet dropouts in a deterministic way. The incidence matrix of a directed spanning tree in the directed communication topology is utilized to construct a linear transformation so that the consensus problems are equivalently transformed into the asymptotic stability problems of reduced-order systems. Then, some sufficient consensus conditions are derived and the consensus protocol gains are designed. Finally, simulation examples are given to show the effectiveness of the proposed results.

摘要 ：
This paper investigates the leader-following consensus problem of multiple single-integrators by using a novel linear transformation method together with the input-to-state stability property. The multi-agent system is assumed to contain a single leader, and we consider the following three cases. 1) The leaders input is pre-given and known by all following agents. 2) The leaders input is unknown. 3) The leaders input is measurable online and transmitted to some of follower agents. By constructing a transformation matrix based on incidence matrix of a virtual leader-rooted spanning tree, we make an equivalent transformation from leader-following consensus problem to an input-to-state stability problem. Then we give a necessary and sufficient condition, which is the Hurwitz stability of a matrix associated with the communication topology, for ensuring the leader-following consensus. In order to efficiently check whether the matrix is Hurwitz stable, especially for large-scale multi-agent systems, we further employ the Hurwitz stability criteria of the matrix based on Metzler matrix theory. Finally, we give numerical examples to validate the theoretical results. © 2021, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

This paper studies the distributed consensus problem of general linear multi-agent systems (MASs) based on a novel decentralized output feedback control approach. By introducing the edge state and a directed-spanning-tree-based linear transformation method, we firstly equivalently transform the consensus problem into the decentralized output feedback stabilization control problem. Then we employ the properties of distributed fixed modes in decentralized output feedback stabilization control problem to derive a necessary and sufficient condition for ensuring the asymptotic state consensus of the MAS under the linear state feedback control. We further present a gradient descent iterative algorithm to design the gain matrix in the linear feedback consensus protocol. Finally, we give a numerical example to demonstrate the effectiveness of the theoretical results.
