• Robust Controller Design for Stochastic Nonlinear Systems via Convex Optimization AI翻译
  作者：Tsukamoto, Hiroyasu; Chung, Soon-Jo

  摘要：This article presents ConVex optimization-based Stochastic steady-state Tracking Error Minimization (CV-STEM), a new state feedback control framework for a class of Ito stochastic nonlinear systems and Lagrangian systems. Its innovation lies in computing the control input by an optimal contraction metric, which greedily minimizes an upper bound of the steady-state mean squared tracking error of the system trajectories. Although the problem of minimizing the bound is nonconvex, its equivalent c...
• On Zeno Behavior in Event-Triggered Finite-Time Consensus of Multiagent Systems AI翻译
  作者：Yu, Hao; Chen, Tongwen
  作者单位：University of Alberta
  摘要：This article studies Zeno behavior, where an infinite number of events occur in a finite-time interval, in the event-triggered multiagent systems that aim at achieving consensus in finite time. Two popular scenarios in the first-order multiagent systems with model-based event-triggered controllers are considered. One is that the event trigger in each agent samples the absolute information, and decides when to broadcast the information to its neighbors, and the other is that the update of contr...
• Toward a Comprehensive Theory for Stability Regions of a Class of Nonlinear Discrete Dynamical Systems AI翻译
  作者：Dias, Elaine Santos; Costa Alberto, Luis Fernando; Amaral, Fabiolo Moraes; Chiang, Hsiao-Dong

  摘要：A comprehensive theory for the stability boundaries and the stability regions of a general class of nonlinear discrete dynamical systems is developed in this article. This general class of systems is modeled by diffeomorphisms and admits as limit sets only fixed points and periodic orbits. Topological and dynamical characterizations of stability boundaries are developed. Necessary and sufficient conditions for fixed points and periodic orbits to lie on the stability boundary are derived. Numer...
• Sparse Polynomial Zonotopes: A Novel Set Representation for Reachability Analysis AI翻译
  作者：Kochdumper, Niklas; Althoff, Matthias
  作者单位：Technical University of Munich
  摘要：We introduce sparse polynomial zonotopes, a new set representation for formal verification of hybrid systems. Sparse polynomial zonotopes can represent nonconvex sets and are generalizations of zonotopes, polytopes, and Taylor models. Operations like Minkowski sum, quadratic mapping, and reduction of the representation size can be computed with polynomial complexity w.r.t. the dimension of the system. In particular, for reachability analysis of nonlinear systems, the wrapping effect is substan...
• The Set of Linear Time-Invariant Unfalsified Models With Bounded Complexity is Affine AI翻译
  作者：Mishra, Vikas Kumar; Markovsky, Ivan
  作者单位：Vrije Universiteit Brussel
  摘要：We consider exact system identification in the behavioral setting: Given an exact (noise-free) finite time series, find the set of bounded complexity linear time-invariant systems that fit the data exactly. First, we modify the notion of the most powerful unfalsified model for the case of finite data by fixing the number of inputs and minimizing the order. Then, we give necessary and sufficient identifiability conditions, i.e., conditions under which the true data generating system coincides w...
• Angle Rigidity and Its Usage to Stabilize Multiagent Formations in 2-D AI翻译
  作者：Chen, Liangming; Cao, Ming; Li, Chuanjiang
  作者单位：University of Groningen; Harbin Institute of Technology
  摘要：Motivated by the challenging formation stabilization problem for mobile robotic teams wherein no distance or relative position measurements are available but each robot can only measure some of relative angles with respect to its neighbors in its local coordinate frame, we develop the notion of angle rigidity for a multipoint framework, named angularity, consisting of a set of nodes embedded in a Euclidean space, and a set of angle constraints among them. Different from bearings or angles defi...

  摘要：Proportional-integral (PI) control/loop has been widely used in numerous industrial processes. This article focuses on integrating uncertainty estimator into PI controller for better robustness and transient performance against uncertain nonlinear coupling dynamics and time-varying disturbances. First, the descriptions for the sizes of three kinds of uncertainties in a class of multi-input-multi-output nonlinear systems are discussed. Then, the tuning laws of the typical uncertainty estimator,...
• A Switching Multiplicative Watermarking Scheme for Detection of Stealthy Cyber-Attacks AI翻译
  作者：Ferrari, Riccardo M. G.; Teixeira, Andre M. H.
  作者单位：Delft University of Technology; Uppsala University
  摘要：This article addresses the detection of stealthy attacks on sensor measurements. Inspired in authentication schemes with weak cryptographic guarantees, we propose a watermarking approach to validate the data and its source. In particular, we propose a multiplicative scheme, where the sensor outputs are watermarked by a bank of filters, then transmitted through the possibly unsecured communication network. The original measurement data are finally reconstructed by a watermark remover. To allow ...
• Efficient Estimation of Equilibria in Large Aggregative Games With Coupling Constraints AI翻译

  摘要：Aggregative games have many industrial applications, and computing an equilibrium in those games is challenging when the number of players is large. In the framework of atomic aggregative games with coupling constraints, we show that variational Nash equilibria of a large aggregative game can be approximated by a Wardrop equilibrium of an auxiliary population game of smaller dimension. Each population of this auxiliary game corresponds to a group of atomic players of the initial large game. Th...
• Adaptive Output Feedback Funnel Control of Uncertain Nonlinear Systems With Arbitrary Relative Degree AI翻译
  作者：Liu, Yong-Hua; Su, Chun-Yi; Li, Hongyi
  作者单位：Guangdong University of Technology
  摘要：This article considers the problem of output feedback funnel control for a class of uncertain nonlinear systems with arbitrary known relative degree. By utilizing the funnel control approach with a barrier Lyapunov function, a novel adaptive output feedback controller is constructed recursively, which accomplishes the output tracking with prescribed transient behavior. The developed control scheme features that the precise knowledge of system nonlinearities, including generally required boundi...
