摘要：This article characterizes the energy-related controllability of composite complex networks. We consider a class of composite networks constructed from simple factor networks via Cartesian product. The considered factor networks are leader-follower signed networks with neighbor-based Laplacian dynamics, adopting positive and negative edges to capture cooperative and competitive interactions among network units. Different from most existing works focusing on classical controllability, this arti...

摘要：This article studies the stabilization to exponential input-to-state stability (ISS) via aperiodic intermittent control (APIC) for continuous-time systems. The stabilization is formulated as a problem of minimum activation time rate (MATR) of nontrivial APIC. The MATR is investigated, respectively, for time-triggered APIC (T-APIC) and event-triggered APIC (E-APIC). The MATR of T-APIC is estimated and the criteria of stabilization to ISS via T-APIC are derived. Moreover, the state dependent E-A...

摘要：This article investigates the problem of global adaptive stabilization for discrete-time nonlinearly parameterized systems with nonaffine inputs. Using the notion of passivity and the idea of small bounded feedback, we present a discrete-time adaptive controller that globally adaptively stabilizes a class of non-affine systems with unknown parameters, under the assumptions that the unforced dynamics are stable and the controllabilitylike rank conditions hold. The latter is shown to be characte...

摘要：A system relying on the collective behavior of decision makers can be vulnerable to a variety of attacks. How well can a system operator protect performance in the face of these risks? We frame this question in the context of graphical coordination games, where the agents in a network choose between two conventions and derive benefits from coordinating neighbors, and system performance is measured in terms of the agents' welfare. In this article, we assess an operator's ability to mitigate two...

摘要：This article presents a computational framework to efficiently generate feasible and safe trajectories for multiple autonomous vehicle operations. We formulate the optimal motion planning problem as a continuous-time optimal control problem, and approximate its solutions in a discretized setting using Bernstein polynomials. The latter possess convenient properties that allow to efficiently compute and enforce constraints along the vehicles' trajectories, such as maximum speed and angular rates...

摘要：This article addresses the bounded synchronization of heterogeneous complex dynamical networks. Different from most existing criteria which deal with only global bounded synchronization, a general theorem is established for analyzing both the local and global bounded synchronization of a class of heterogeneous networks in a unified approach. By developing a joint-diagonalization-like technique, several easy-to-use bounded synchronization criteria with low-dimensional linear matrix inequalities...

摘要：The sigma-point filters, such as the unscented Kalman filter, are popular alternatives to the ubiquitous extended Kalman filter. The classical quadrature rules used in the sigma-point filters are motivated via polynomial approximation of the integrand; however, in the applied context, these assumptions cannot always be justified. As a result, a quadrature error can introduce bias into estimated moments, for which there is no compensatory mechanism in the classical sigma-point filters. This can...

摘要：We consider the problem of designing distributed controllers to guarantee dissipativity of a networked system comprised of dynamically coupled subsystems. We require that the control synthesis is carried out locally at the subsystem-level, without explicit knowledge of the dynamics of other subsystems in the network. We solve this problem in two steps. First, we provide distributed subsystem-level dissipativity analysis conditions whose feasibility is sufficient to guarantee dissipativity of t...

摘要：In this article, we introduce novel filter design conditions for discrete-time linear parameter-varying (LPV) systems. The two main features of the proposed conditions are: the ability of handling LPV systems subject to variation in all matrices of the system and the generalization for systems with bounded rates of parameter variation. Filter stability and H-infinity filtering problems are addressed through poly-quadratic Lyapunov functions in terms of linear matrix inequalities. Numerical exa...

摘要：A target-attacker-defender (TAD) game is a fascinating differential game in both nature and the artificial world. This article considers a TAD game with a nonsuicidal faster attacker that aims to capture the target while avoiding being captured by the defender. The attacker is both a pursuer (pursues the target) and an evader (evades the defender). Naturally, one wonders when and how the attacker can chase the target and when and how the attacker can evade the defender. In this article, we fir...
