  摘要：This article investigates the distributed optimal coordination problem and distributed constrained optimal coordination problem for multiple heterogeneous linear systems over a directed communication network. The objective is to develop distributed optimization algorithms for a set of heterogeneous linear agents over a directed communication network, which will drive the decision variables of the agents to the optimal state with optimal system performance. First, a new distributed optimal coor...
• Switching-Based Deployment of Multiagent Systems Using Kuramoto-Sivashinsky Model AI翻译
  作者：Zhang, Jing; Kang, Wen; Wang, Jun-Min

  摘要：This article addresses the switching-based deployment of multiagent systems using the Kuramoto-Sivashinsky model. Based on the output measurements, a switching control law is proposed to select only one leader for data transmission. The leader-actuated closed-loop system is modeled by a nonlinear Kuramoto-Sivashinsky equation. Sufficient conditions are derived to guarantee the exponential stability of the resulting system via the time-delay approach and Halanay's inequality. Finally, simulatio...
• An LMI Formulation of Small-Gain Theorems for 2-Contraction of Nonlinear Interconnected Systems AI翻译

  摘要：This article introduces small-gain sufficient conditions for 2-contraction of feedback interconnected systems, on the basis of individual gains of suitable subsystems arising from a modular decomposition of the second additive compound matrix variational equation. The gains are computed through the solution of suitable linear matrix inequality conditions. The criterion applies even to cases when individual subsystems might fail to be contractive, thanks to the extra margin of contraction affor...
• A Polynomial-Based Approach of Reachable Set Estimation for Periodic Time-Varying Systems AI翻译

  摘要：This article is focused on estimating reachable sets for periodic time-varying systems, whose dynamics are represented by trigonometric series through Fourier theory. Given the difficulty of dealing with coupled time-varying coefficients in reachable set estimation, a constructive polynomial-based approach is utilized to transform time-varying nonconvex constraints into constant vertex constraints through the property of multiaffine matrix polynomials. Based on that, when the decay rate parame...
• Matrix-Scheduling of QSR-Dissipative Systems AI翻译
  作者：Moalemi, Sepehr; Forbes, James Richard
  作者单位：McGill University
  摘要：This article considers gain-scheduling of quadratic supply rate (QSR)-dissipative subsystems using scheduling matrices. The corresponding QSR-dissipative properties of the overall matrix-gain-scheduled system, which depends on the QSR properties of the subsystems scheduled, are explicitly derived. The use of scheduling matrices is a generalization of the scalar scheduling signals used in the literature, and allows for greater design freedom when scheduling systems, such as in the case of gain-...
• Homotopic Gaussian Mixture Filtering for Applied Bayesian Inference AI翻译

  摘要：Bayes' rule, although a powerful framework for performing state estimation, is often intractable for real-world, nonlinear dynamic systems. As a result, estimation algorithms typically rely on a simplifying assumption, such as the linearity of the measurement model or Gaussianity of the likelihood function. For nonlinear, non-Gaussian systems, these approximations can introduce statistical inconsistencies into the underlying estimator. To mitigate approximation errors, a homotopic scheme is pr...
• Dynamic Event-Triggering Mechanism and Its Application to Dynamic Average Tracking AI翻译
  作者：Xu, Tao; Yi, Xiaojian; Duan, Zhisheng; Chen, Guanrong; Wen, Guanghui

  摘要：As reported in the studies of dynamic average tracking, many existing solutions are not robust to initialization, in the sense that their design and implementation require specific and stringent initial conditions. All agents need to be reinitialized if the original initial conditions are violated due to network disruptions. This article aims to overcome this common issue existing in the control problem of distributed event-driven dynamic average tracking for networked multiple linear systems ...
• Finite-time Bipartite Synchronization of Homogeneous and Heterogeneous Multiple Agents with Input Saturation: A TVRE-Based Gain Approach AI翻译
  作者：Zhou, Yuan; Liu, Yongfang; Zhao, Yu; Li, Zhongkui
  作者单位：Hong Kong Polytechnic University; Northwestern Polytechnical University; Peking University
  摘要：Pursuing faster convergence rates and smaller input magnitudes seem to be two conflicting goals in studying multiagent systems. To give a tradeoff between the two, this article focuses on the bipartite synchronization problems over signed topologies and aims to achieve finite-time control for general linear agents subject to input saturation constraints. First, this article considers homogeneous agents and presents a class of bipartite synchronization protocols with saturation constraint, whic...

  摘要：This article formulates algorithms to upper-bound the maximum value-at-risk (VaR) of a state function along trajectories of stochastic processes. The VaR is upper bounded by two methods: minimax tail-bounds (Cantelli/Vysochanskij-Petunin) and Expected Shortfall (ES)/Conditional VaR. Tail-bounds lead to an infinite-dimensional second order cone program (SOCP) in occupation measures, while the ES approach creates a linear program (LP) in occupation measures. Under compactness and regularity cond...
• On the Relationship Between Stochastic Turnpike and Dissipativity Notions AI翻译

  摘要：In this article, we introduce and study different dissipativity notions and different turnpike properties for discrete-time stochastic nonlinear optimal control problems. The proposed stochastic dissipativity notions extend the classic notion of Jan C. Willems to $\mathit {L<^>{r}}$ random variables and to probability measures. Our stochastic turnpike properties range from a formulation for random variables via turnpike phenomena in probability and in probability measures to the turnpike prope...
