  摘要：As multi-agent systems proliferate and more user data, new approaches are needed to protect sensitive data while still enabling system operation. To address this need, this article presents a private multiagent LQ control framework. Agents' state trajectories can be sensitive, and we therefore protect them using differential privacy. We quantify the impact of privacy along three dimensions: the amount of information shared under privacy, the control-theoretic cost of privacy, and the tradeoffs...
• Restart of Accelerated First-Order Methods With Linear Convergence Under a Quadratic Functional Growth Condition AI翻译
  作者：Alamo, Teodoro; Krupa, Pablo; Limon, Daniel

  摘要：Accelerated first-order methods, also called fast gradient methods, are popular optimization methods in the field of convex optimization. However, they are prone to suffer from oscillatory behavior that slows their convergence when medium to high accuracy is desired. In order to address this, restart schemes have been proposed in the literature, which seek to improve the practical convergence by suppressing the oscillatory behavior. This article presents a restart scheme for accelerated first-...
• DC Power Grids With Constant-Power Loads-Part II: Nonnegative Power Demands, Conditions for Feasibility, and High-Voltage Solutions AI翻译
  作者：Jeeninga, Mark; De Persis, Claudio; van der Schaft, Arjan

  摘要：In this two-part article, we develop a unifying framework for the analysis of the feasibility of the power flow equations for dc power grids with constant-power loads. Part II of this article, explores further implications of the results in Part I. We present a necessary and sufficient linear matrix inequality (LMI) condition for the feasibility of a vector of power demands (under small perturbation), which extends a necessary condition in the literature. The alternatives of these LMI conditio...

  摘要：A high-order sliding-mode adaptive observer is proposed to solve the problem of an adaptive estimation, i.e., the simultaneous estimation of the state and parameters, for a class of uncertain nonlinear systems in the presence of external disturbances, which do not need to satisfy a relative degree condition equal to one. This approach is based on a high-order sliding-mode observer and a nonlinear parameter identification algorithm. The practical, global, and uniform asymptotic stability of the...
• Optimal Selection and Tracking Of Generalized Nash Equilibria in Monotone Games AI翻译
  作者：Benenati, Emilio; Ananduta, Wicak; Grammatico, Sergio
  作者单位：Delft University of Technology
  摘要：A fundamental open problem in monotone game theory is the computation of a specific generalized Nash equilibrium (GNE) among all the available ones, e.g., the optimal equilibrium with respect to a system-level objective. The existing GNE seeking algorithms have in fact convergence guarantees toward an arbitrary, possibly inefficient, equilibrium. In this article, we solve this open problem by leveraging results from fixed-point selection theory and in turn derive distributed algorithms for the...
• Detection and Localization of Stealthy Cyberattacks in Cyber-Physical Discrete Event Systems AI翻译
  作者：Fritz, Raphael; Zhang, Ping
  摘要：The widespread use of cyber-physical systems not only brings new opportunities with it but also introduces the risk of cyberattacks on the system. One of the most dangerous and sophisticated types of attacks are the stealthy attacks that can hide their influence and are not detectable by conventional anomaly detection schemes. In this article, a detection method for the replay attack and the covert attack on discrete event systems is proposed. Unexpected behavior is introduced into the transmi...
• A Compositional Dissipativity Approach for Data-Driven Safety Verification of Large-Scale Dynamical Systems AI翻译
  作者：Lavaei, Abolfazl; Soudjani, Sadegh; Frazzoli, Emilio

  摘要：This work is concerned with a compositional data-driven approach for formal safety verification of large-scale continuous-time dynamical systems with unknown models. The proposed framework enjoys the interconnection matrix and joint dissipativity-type properties of subsystems, described by the notion of stochastic storage certificates. In the first part of the paper, we cast the required conditions for constructing storage certificates as a robust optimization program (ROP). Since the proposed...
• Luenberger-Like Observer Design and Optimal State Estimation of Logical Control Networks With Stochastic Disturbances AI翻译
  作者：Li, Yalu; Li, Haitao; Xiao, Gaoxi
  作者单位：Shandong Normal University; Nanyang Technological University
  摘要：State estimation is important for the synthesis of nonlinear systems with stochastic disturbances. This work devotes to tackling the optimal state estimation problem of logical control networks (LCNs) with stochastic disturbances. First, based on the algebraic form of LCNs with stochastic disturbances, an effective approach is proposed to design the Luenberger-like observer. Second, by resorting to the Luenberger-like observer, a new criterion is presented to obtain the optimal state estimator...
• Frequency Domain Identification of Continuous-Time Hammerstein Systems With Adaptive Continuous-Time Rational Orthonormal Basis Functions AI翻译

  摘要：In this article, we propose a new identification method for continuous-time Hammerstein systems. This method is based on the adaptive generalized rational orthonormal basis functions. In particular, we use the strategy in which poles of basis functions are selected one by one in terms of a criterion. By doing this, we not only take advantage of the variability of the generalized orthogonal basis functions, but also reduce the computational burden. The proposed algorithm is adaptive. Meanwhile,...
• A Lyapunov Function for Robust Stability of Moving Horizon Estimation AI翻译

  摘要：We provide a novel robust stability analysis for moving horizon estimation (MHE) using a Lyapunov function. In addition, we introduce linear matrix inequalities (LMIs) to verify the necessary incremental input/output-to-state stability (delta-IOSS) detectability condition. We consider an MHE formulation with time-discounted quadratic objective for nonlinear systems admitting an exponential delta-IOSS Lyapunov function. We show that with a suitable parameterization of the MHE objective, the del...
