摘要：In this article, coverage control for mobile sensors with double-integrator dynamics and different maximum velocities on a circle is investigated. A generalized energy function is introduced in the proposed coverage control laws to guarantee order preservation of the sensors despite of the existence of unknown but bounded disturbances. The velocity constraint of each sensor is shown to be always satisfied throughout the coverage task. It is shown that the sensor network can be driven to a neig...

摘要：Attractivity specifications consist in driving the state of a system to a target region and to keep it in that region afterward. In this article, we develop an approach to controller synthesis for attractivity specifications based on iterative refinements of symbolic abstractions. We compute iteratively sequences of least-violating attractivity controllers and of associated attractors. The current controller is used to restrict possible control actions at the next iteration where a new abstrac...

摘要：This study discusses a two-person zero-sum game for finite-horizon semi-Markov processes, where the concerned criterion is the probability that the total payoff produced by a system during a finite horizon exceeds a prescribed goal. We establish the Shapley equation and the existence of a saddle point under a suitable condition. Moreover, we develop a value iterative algorithm to compute an e-saddle point and approach the value of the game by solving a series of matrix games. The construction ...

摘要：This article investigates the regional stability and performance of antiwindup compensation for the leader-follower consensus problem of linear multiagent systems, where the leader is subject to nonzero control input and external disturbance, and each follower is subject to magnitude and rate bounded input, as well as external disturbance. First, a distributed dynamic output feedback is proposed for the unconstrained case, which establishes an invariant set, based on the peak-to-peak approach....

摘要：This article introduces a computational framework to identify nonlinear input-output operators that fit a set of system trajectories while satisfying incremental integral quadratic constraints. The data fitting algorithm is thus regularized by suitable input-output properties required for system analysis and control design. This biased identification problem is shown to admit the tractable solution of a regularized least squares problem when formulated in a suitable reproducing kernel Hilbert ...

摘要：This article studies set-membership estimation for discrete-time linear time-varying systems with unknown-but-bounded uncertainties. An ellipsoidal set-membership filtering method with a new estimator is proposed. Based on the S-procedure, the proposed set-membership filtering is formulated as an optimization problem in terms of linear matrix inequalities. Moreover, it is shown that the optimal ellipsoids estimated by two existing set-membership filtering approaches are equivalent to the optim...

摘要：We consider the problem of estimating the states of a distributed network of nodes (targets) through a team of cooperating agents (sensors) persistently visiting the nodes so that an overall measure of estimation error covariance evaluated over a finite period is minimized. We formulate this as a multiagent persistent monitoring problem where the goal is to control each agent's trajectory defined as a sequence of target visits and the corresponding dwell times spent making observations at each...

摘要：A sparsity pattern in R-nxm, for m >= n, is a vector subspace of matrices admitting a basis consisting of canonical basis vectors in R-nxm. We represent a sparsity pattern by a matrix with 0/star-entries, where star-entries are arbitrary real numbers and 0-entries are equal to 0. We say that a sparsity pattern has full structural rank if the maximal rank of matrices contained in it is n. In this article, we investigate the degree of resilience of patterns with full structural rank: We address ...

摘要：This article studies reduced-order modeling of dynamic networks with strongly connected topology. Given a graph clustering of an original large-scale network, we construct a quotient graph with less number of vertices, where the edge weights are parameters to be determined. The model of a reduced network is thereby obtained with parameterized system matrices, and then, an edge weighting procedure is devised, aiming to select an optimal set of edge weights to minimize the approximation error be...

摘要：In this article, we consider a game-theoretic framework for cyber-physical systems, where a defender develops a mitigation strategy against an intelligent attacker who exploits the system's uncertainty to remain undetected. The goal of the defender is to optimize a performance cost constructed specifically to account for robustness against stealthy attacks so that the system is regulated. Conversely, the goal of the attacker is to disrupt the system's performance by leveraging its significant ...
