摘要 ：
This study deals with the problem of gain-scheduled robust control for multi-agent linear parameter varying (LPV) systems with or without communication delays. The system matrices are assumed to depend on the scheduling parameters, which are supposed to be time-varying within a priori known bounds. First, a linear transformation matrix is constructed from the directed spanning tree of the communication topology of the agents, which equivalently transforms the robust consensus control problem of multi-agent LPV systems into the robust stability problem of a set of parameter-dependent systems. What's more, the effect of the time-varying communication delays is considered, and consensus condition in terms of linear matrix inequalities (LMIs) is derived by using the parameter-dependent Lyapunov-Krasovskii approach. Then, the control gain matrices are obtained through solving a convex optimization problem. Finally, a numerical example is provided to illustrate the effectiveness of the proposed method.

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.

摘要 ：
This study presents a distributed observer-based H infinity consensus control for general linear multi-agent systems under measurement noises and external disturbances. By using the state linear transformation with the matrix constructed from the incidence matrix of a virtual chained directed spanning tree, we transform the observer-based consensus problem into an asymptotic stability problem of a corresponding augmented linear system. The augmented linear system consists of the reduced-order system deduced from dynamic equations of the agents and state estimation error system. Based on asymptotic stability of the augmented linear system, we present some sufficient conditions in terms of linear matrix inequalities for the existence of the distributed observer-based H infinity consensus controller. Finally, the effectiveness of the proposed approach is illustrated by a numerical example.

摘要 ：
This paper is concerned with the problem of fault detection and consensus control via event-triggered scheme for a class of linear multi-agent systems subject to external disturbances. For the network of multi-agent systems with unknown faults and disturbances, the event-triggered consensus protocol and observer-based fault detection filter are designed simultaneously. Through the model transformation and decomposition, the specific design problem can be transformed into a multi-objective optimization problem by using a mixed H∞/H− method. Based on the Lyapunov-Krasovskii Theory and Projection Lemma, some sufficient conditions, which ensure the decomposed system is not only asymptotically stable, but also satisfies the prescribed optimization performance constraints, are derived in the form of linear matrix inequalities. Finally, two simulation examples are provided to verify the practicality and validity of the theoretical results. © 2021 The Franklin Institute

摘要 ：
This paper focuses on the consensus control and fault estimation problems for a class of time-delayed multi-agent systems with Markov switching topologies. Two different event-triggered mechanisms are adopted with hope to reduce burden of shared network and improve energy efficiency. Under Markov process, by establishing the consensus control protocol and designing a novel adaptive fault estimation observer, the consensus control and fault estimation problems are transformed into two stochastic stability problems in different forms. Then, according to the switching Lyapunov function method and free-weighting matrix technique, two delay-dependent stability criteria on the consensus control and fault estimation are derived, respectively. However, the two criteria containing nonlinear coupling terms are not standard linear matrix inequalities (LMIs) and cannot be solved directly with the LMI toolbox. In order to eliminate the coupling terms, two improved path-following algorithms are presented. These algorithms depend on the initial conditions, so it is very crucial to choose the appropriate preset parameters. The computational complexity is increasing with the number of iterations, system size and matrix dimension, which is a fully new challenge for the study of consensus control and fault estimation of multi-agent systems. Based on the algorithms, the switching consensus controller gains and model gain matrices of fault estimation can be efficiently solved out. Finally, a simulation example of tailless fighter airplanes is given to illustrate the practicality and validity of the theoretical results. (c) 2021 Elsevier B.V. All rights reserved.

摘要 ：
针对一类具有输入时滞的主动悬架系统,提出了鲁棒补偿控制方法。根据半车主动悬架动力学模型设计时延补偿向量用于构成控制输入,为此构造了相应的Lyapunov函数,解决鲁棒稳定性的问题。为了解决系统状态不完全可测的问题,采取变量替换法,实现有限可检测状态量的静态输出反馈控制。采用Lyapunov理论和线性矩阵不等式,设计多目标协同控制器,同时提高主动悬架系统的乘坐舒适性及操纵稳定性,并考虑悬架主动控制力、轮胎动载荷和执行器饱和等约束。通过在不同的时滞工况下对其进行动力学仿真分析,验证了该方法在不平路面扰动仍保持鲁棒稳定和满足一定的系统性能。
