• Dynamic Information Sharing and Punishment Strategies AI翻译

  摘要：In this article, we study the problem of information sharing among rational self-interested agents as a dynamic game of asymmetric information. We assume that the agents imperfectly observe a Markov chain, and they are called to decide whether they will share their noisy observations or not at each time instant. We utilize the notion of conditional mutual information to evaluate the information being shared among the agents. The challenges that arise due to the interdependence of agents' infor...
• A Successive Pseudospectral-Based Approximation of the Solution of Regulator Equations AI翻译

  摘要：Through the combination of contraction mapping and pseudospectral method, we propose a successive approximation technique to approximate the solution of a class of regulator equations with periodic exosystems and hyperbolic zero dynamics. In this scheme, the initial points of flows on the zero-error constrained manifolds are approximated successively as the fixed point of a contractive integral mapping. Accordingly, flows are obtained by utilizing the scaled Fourier-Gauss-Radau collocation met...
• Compensator-Based Output Feedback Stabilizers for a Class of Planar Systems With Unknown Structures and Measurements AI翻译

  摘要：This article considers the problem of output feedback stabilization for a class of nonlinear planar systems with unknown structures and measurements, which prevent the construction of conventional state observers. By taking advantage of the stability-increasing capability of a lead compensator, we propose a dynamic output feedback controller to globally stabilize the uncertain planar systems. For the special case of linear planar systems with unknown coefficients, a finite-time output feedback...
• Transfer-Entropy-Regularized Markov Decision Processes AI翻译

  摘要：We consider the framework of transfer-entropy-regularized Markov decision process (TERMDP) in which the weighted sum of the classical state-dependent cost and the transfer entropy from the state random process to the control input process is minimized. Although TERMDPs are generally formulated as nonconvex optimization problems, an analytical necessary optimality condition can be expressed as a finite set of nonlinear equations, based on which an iterative forward-backward computational proced...
• Policy Evaluation and Seeking for Multiagent Reinforcement Learning via Best Response AI翻译

  摘要：Multiagent policy evaluation and seeking are long-standing challenges in developing theories for multiagent reinforcement learning (MARL), due to multidimensional learning goals, nonstationary environment, and scalability issues in the joint policy space. This article introduces two metrics grounded on a game-theoretic solution concept called sink equilibrium, for the evaluation, ranking, and computation of policies in multiagent learning. We adopt strict best response dynamics (SBRDs) to mode...
• Distributed Fault Accommodation of Multiple Sensor Faults for a Class of Nonlinear Interconnected Systems AI翻译
  作者：Zhao, Dong; Polycarpou, Marios M.
  作者单位：University of Cyprus; University of Cyprus
  摘要：This article considers the design and analysis of a distributed sensor fault accommodation scheme for a class of nonlinear systems, modeled as interconnected subsystems. Each subsystem is subject to possible local sensor faults or may be impacted by a sensor fault in a neighboring subsystem due to the exchange of information between neighboring controllers. The proposed adaptive approximation-based distributed fault accommodation scheme is triggered in the event that a sensor fault is detected...
• Nonlinear Robust Coordinated PSS-AVR Control for a Synchronous Generator Connected to an Infinite Bus AI翻译
  作者：Verrelli, Cristiano Maria; Marino, Riccardo; Tomei, Patrizio; Damm, Gilney
  作者单位：University of Rome Tor Vergata; Universite Gustave-Eiffel
  摘要：The transient stabilization and voltage regulation problem for a synchronous generator connected to an infinite bus is addressed, in this article, in the presence of all uncertain physical parameters. First, new interpretations for the desensitized four loops regulator, here referred to as robust coordinated power system stabilizer and automatic voltage regulator (PSS-AVR) are derived in terms of minimum phase properties with respect to a suitably chosen output for the linearized error system....
• Angle-Based Sensor Network Localization AI翻译
  作者：Jing, Gangshan; Wan, Changhuang; Dai, Ran

  摘要：This article studies angle-based sensor network localization (ASNL) in a plane, which is to determine locations of all sensors in a sensor network, given locations of partial sensors (called anchors) and angle measurements obtained in the local coordinate frame of each sensor. First, it is shown that a framework with a nondegenerate bilateration ordering must be angle fixable, implying that it can be uniquely determined by angles between edges up to translations, rotations, reflections, and un...
• The Effect of Time Delay on the Average Data Rate and Performance in Networked Control Systems AI翻译

  摘要：This article studies the performance of a feedback control loop closed via an error-free digital communication channel with transmission delay. The system comprises a discrete-time noisy linear time-invariant plant, whose single measurement output is mapped into its single control input by a causal, but otherwise arbitrary, coding and control scheme. We consider a single-input multiple-output channel between the encoder-controller and the decoder-controller, which is lossless and imposes rando...
• Generalized Proportional Allocation Policies for Robust Control of Dynamical Flow Networks AI翻译
  作者：Nilsson, Gustav; Como, Giacomo

  摘要：We study a robust control problem for dynamical flow networks. In the considered framework, traffic flows along the links of a transportation network-modeled as a capacited multigraph-and queues up at the nodes, whereby control policies determine which incoming queues are to be allocated service simultaneously, within some predetermined scheduling constraints. We first prove fundamental performance limitations on the system performance by showing that for a dynamical flow network to be stabili...
