• Equi-Normalized Robust Positively Invariant Sets AI翻译
  作者：Rakovic, Sasa V.; Zhang, Sixing
  作者单位：Beijing Institute of Technology; Beijing Information Science & Technology University
  摘要：This note revisits the equi-normalization process of robust positively invariant sets so as to enable its use for more general disturbance sets and to provide a systematic, dynamically compatible, and computationally inexpensive design of the collections of points that generate equi-normalized robust positively invariant sets.
• Bearing-Based Formation With Disturbance Rejection AI翻译
  作者：Cheng, Haoshu; Huang, Jie
  作者单位：Chinese University of Hong Kong
  摘要：This article considers the problem of the bearing-based formation control with disturbance rejection for a group of agents under the leader-follower structure. The disturbances are in the form of trigonometric polynomials with arbitrary unknown amplitudes, unknown initial phases, and known or unknown frequencies. For the case of the known frequencies, we employ the canonical internal model to solve the problem, and, for the case of the unknown frequencies, we combine the canonical internal mod...

  摘要：We propose a method for analyzing the distributed random coordinate descent algorithm for solving separable resource allocation problems in the context of an open multiagent system, where agents can be replaced during the process. In particular, we characterize the evolution of the distance to the minimizer in expectation by following a time-varying optimization approach which builds on two components. First, we establish the linear convergence of the algorithm in closed systems, in terms of t...
• Methodologies for Quantifying and Optimizing the Price of Anarchy AI翻译

  摘要：The use of game theory for the analysis and design of socio-technological systems has received significant attention as it enables the quantification of the system-level performance while accounting for the presence of individual decision makers. In this context, a popular metric for analyzing the system-level performance is the price of anarchy (PoA), which measures the loss in efficiency caused by distributed decision making. Over the past two decades, significant effort has been devoted to ...
• Distributed Estimation and Control for LTI Systems Under Finite-Time Agreement AI翻译
  作者：Fioravanti, Camilla; Makridis, Evagoras; Oliva, Gabriele; Vrakopoulou, Maria; Charalambous, Themistoklis
  作者单位：University Campus Bio-Medico - Rome Italy; University of Cyprus
  摘要：This article considers a strongly connected network of agents, each capable of partially observing and controlling a discrete-time linear time-invariant (LTI) system that is jointly observable and controllable. Additionally, agents collaborate to achieve a shared estimated state, computed as the average of their local state estimates. Recent studies suggest that increasing the number of average consensus steps between state estimation updates allows agents to choose from a wider range of state...
• Optimization-Free Control of Safety-Critical Systems Subject to the Intersection of Multiple Time-Varying Concave Constraints AI翻译
  作者：Hosseinzadeh, Mehdi
  作者单位：Washington State University
  摘要：The explicit reference governor (ERG) is an add on unit that provides the constraint handling capability to a prestabilized system by providing the system with an applied reference which is the best approximation of the desired reference at any time and converges to the desired reference. One of the main strengths of ERG is that it does not make use of any online optimization, which makes it an appropriate solution for real-time applications; in particular, it has been shown that ERG has poten...
• Distributed MPC for Self-Organized Cooperation of Multiagent Systems AI翻译
  作者：Koehler, Matthias; Mueller, Matthias A.; Allgoewer, Frank
  作者单位：University of Stuttgart; Leibniz University Hannover
  摘要：In this article, we present a sequential distributed model predictive control (MPC) scheme for cooperative control of multiagent systems with dynamically decoupled heterogeneous nonlinear agents subject to individual constraints. In the scheme, we explore the idea of using tracking MPC with artificial references to let agents coordinate their cooperation without external guidance. Each agent combines a tracking MPC with artificial references, the latter penalized by a suitable coupling cost. T...
• RL-ARNE: A Reinforcement Learning Algorithm for Computing Average Reward Nash Equilibrium of Nonzero-Sum Stochastic Games AI翻译

  摘要：Stochastic games model the strategic interactions between two or more players that occur in a sequence of stages. In this article, we focus on computing the average reward Nash equilibrium (ARNE) of a nonzero-sum stochastic game when the transition probabilities of the game and reward structure of the players are unknown. We note that the current state-of-the-art reinforcement learning (RL) algorithms that compute the ARNE of nonzero-sum stochastic games require solving a matrix game correspon...
• Acoustic Boundary Output Feedback Stabilization of Dynamic n-τ Model Flame via Duct With Variable Cross Section AI翻译
  作者：Wilhelmsen, Nils Christian A.; Di Meglio, Florent
  作者单位：Universite PSL; MINES ParisTech
  摘要：We propose an output feedback controller to stabilize thermoacoustic instabilities in a duct with variable cross section, by actuating and sensing the acoustic boundary opposite from the flame. A linear parametric state-space model, taking into account both time-delay effects from the classical n - tau model and low-pass filtering effects, models the flame subsystem. For the acoustics, a distributed model taking into account variations in the cross-sectional area along the duct is developed an...
• Adaptive Pseudoinverse Observers for Output Redundant Discrete-Time Linear Systems AI翻译
  作者：Cristofaro, Andrea; Zaccarian, Luca
  作者单位：Sapienza University Rome; Universite de Toulouse; Centre National de la Recherche Scientifique (CNRS); University of Trento
  摘要：We address the problem of output redundancy in discrete-time linear systems, with the aim of obtaining an optimized combination of sensors for structurally rejecting certain disturbances.We frame our goal as the design problem of a nonlinear observer consisting in a linear Luenberger structure augmented with an adaptive weighted pseudoinverse combination of the available measurements. A novel optimization algorithm is proposed for the update of the dynamic weights of the pseudoinverse, togethe...
