摘要：Distributed networked systems with Laplacian dynamics play a crucial role in various fields, such as engineering, biology, system science, social science, and physics. To optimize the synchronization performance of such networks, topological adjustments have been identified as effective and efficient ways. This article establishes a theoretical framework for accelerating synchronization convergence by introducing an additional directed edge or increasing edge weight to a network topology. The ...

摘要：In this study, we address the formation control of uncertain multiagent systems with a safety requirement of collision avoidance. The control inputs are determined through quadratic programming (QP) solvers, where both the control Lyapunov function condition and control barrier function condition serve as constraints in the QP problem to achieve the control and safety objectives, respectively. In this work, the Bayesian theorem plays a crucial role in two key aspects. First, the unknown uncert...

摘要：The linear programming (LP) approach is, together with value iteration and policy iteration, one of the three fundamental methods to solve optimal control problems in a dynamic programming setting. Despite its simple formulation, versatility, and predisposition to be employed in model-free settings, the LP approach has not enjoyed the same popularity as the other methods. The reason is the often poor scalability of the exact LP approach and the difficulty to obtain bounded solutions for a reas...

摘要：This article studies rigid formation control of multiagent systems with nonlinear uncertainties. Unlike most existing research, ratio-of-distance (RoD) rigidity theory is introduced, and nonlinear uncertainties are thoroughly discussed. Desired formation shapes are formulated by a special class of RoD-based rigid frameworks. This article considers how to design distributed adaptive control protocols to drive all agents to acquire and maintain desired formation shapes while simultaneously maneu...

摘要：In this article, we investigate a data-driven approach to the design of an unknown-input observer (UIO). Specifically, we provide necessary and sufficient conditions for the existence of a UIO for a discrete-time linear time-invariant system, designed based only on some available data, obtained on a finite time window. We also prove that, under weak assumptions on the collected data, the solvability conditions derived by means of the data-driven approach are in fact equivalent to those obtaine...

摘要：In this article, we study incrementally exponentially stable (IES) image and kernel representations for nonlinear systems with the aim of generalizing the Youla-Kucera parameterization in the contraction framework. We first construct these representations and their stable inverses in the contraction framework and then provide a parameterization of stabilizing controllers by additionally assuming incremental input-to-state stability for the image representation. Focusing on constant metrics res...

摘要：Time-optimal control for high-order chain-of-integrators systems with full state constraints and arbitrarily given terminal states remains a challenging problem in the optimal control theory domain, yet to be resolved. To enhance further comprehension of the problem, this article establishes a novel notation system and theoretical framework, providing the switching manifold for high-order problems in the form of switching laws. Through deriving properties of switching laws regarding signs and ...

摘要：In this article, iterative algorithms are investigated to solve the Riccati algebraic matrix equations arising in the context of linear quadratic (LQ) optimal control of discrete-time Markov jump systems. By using the matrix inversion lemma, an equivalent form for the considered coupled Riccati matrix equation is constructed, and then two intermediate variables are introduced to further construct a new equivalent form in order to avoid the operation of matrix inversion. With the aid of the obt...

摘要：The maximum absolute correlation between regressors, which is called mutual coherence, plays an essential role in sparse estimation. A regressor matrix whose columns are highly correlated may result from optimal input design, since there is no constraint on the mutual coherence, making it difficult to handle sparse estimation. This article aims to tackle this issue for fixed denominator models, which include Laguerre, Kautz, and generalized orthonormal basis function expansion models, for exam...

摘要：Distributed Nash equilibrium (NE) seeking problems for networked games have been widely investigated in recent years. Despite the increasing attention, communication expenditure is becoming a major bottleneck for scaling up distributed approaches within limited communication bandwidth between agents. To reduce communication cost, an efficient event-triggered and compressed distributed NE seeking (ETC-DNES) algorithm is proposed in this article to obtain an NE for games over directed graphs, wh...
