  摘要：This article reports an algorithm formultiagent distributed optimization problems with a common decision variable, local linear equality, and inequality, constraints and set constraints with convergence rate guarantees. The algorithm accrues all the benefits of the alternating direction method of multipliers (ADMM) approach. It also overcomes the limitations of existing methods on convex optimization problems with linear inequality, equality, and set constraints by allowing directed communicat...
• Reduced Model Reconstruction Method for Stable Positive Network Systems AI翻译
  作者：Sato, Kazuhiro
  作者单位：University of Tokyo; University of Tokyo
  摘要：We consider a reconstruction problem of a reduced stable positive network system with the preservation of the original interconnection structure based on an H-2 optimal model reduction problem with constraints. To this end, we define an important set using the Perron-Frobenius theory of nonnegative matrices such that all elements of the set are stable and Metzler. Using the projection onto the set, we propose a cyclic projected gradient method to produce a better reduced model than an initial ...
• Event-Triggered Adaptive Control of a Parabolic PDE-ODE Cascade With Piecewise-Constant Inputs and Identification AI翻译
  作者：Wang, Ji; Krstic, Miroslav
  作者单位：Xiamen University; University of California System; University of California San Diego
  摘要：We present an adaptive event-triggered boundary control scheme for a parabolic partial differential equation-ordinary differential equation (PDE-ODE) system, where the reaction coefficient of the parabolic PDE and the system parameter of a scalar ODE, are unknown. In the proposed controller, the parameter estimates, which are built by batch least-square identification, are recomputed and the plant states are resampled simultaneously. As a result, both the parameter estimates and the control in...
• On the Admissibility and Stability of Multiagent Nonlinear Interconnected Positive Systems With Heterogeneous Delays AI翻译

  摘要：Many multiagent interconnected systems include typical nonlinearities, which are highly sensitive to inevitable communication delays. This makes their analysis challenging and the generalization of results from linear interconnected systems theory to those nonlinear interconnected systems very limited. This article deals with the analysis of multiagent nonlinear interconnected positive systems (MANIPS). The main contributions of this work are twofold. Based on Perron-Frobenius theorem, we firs...
• Abstraction Refinement for Attractivity Controllers Using Quantitative Synthesis AI翻译

  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...
• Zero-Sum Games for Finite-Horizon Semi-Markov Processes Under the Probability Criterion AI翻译
  作者：Huang, Xiangxiang; Guo, Xianping; Wen, Xin
  作者单位：Dongguan University of Technology; Sun Yat Sen University; Sun Yat Sen University
  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 ...
• Leader-Follower Consensus of Linear Multiagent Systems With Magnitude and Rate Saturation and an Active Leader AI翻译
  作者：Li, Pengyuan; Jabbari, Faryar; Sun, Xi-Ming
  作者单位：Dalian Maritime University; University of California System; University of California Irvine; Dalian University of Technology
  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....
• Kernel-Based Models for System Analysis AI翻译
  作者：van Waarde, Henk J.; Sepulchre, Rodolphe
  作者单位：University of Groningen; University of Cambridge
  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 ...
• Ellipsoidal Set-Membership Filtering for Discrete-Time Linear Time-Varying Systems AI翻译
  作者：Wang, Zhenhua; Zhang, Yilian; Shen, Mouquan; Shen, Yi
  作者单位：Harbin Institute of Technology; Shanghai Maritime University; Nanjing Tech University
  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...
• Distributed Estimation in Network Systems Using Event-Driven Receding Horizon Control AI翻译
  作者：Welikala, Shirantha; Cassandras, Christos G.
  作者单位：University of Notre Dame; Boston University; Boston University
  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...
