  摘要：In this article, the problem of lossless state compression of Boolean control networks is first investigated. Two compression protocols are introduced, based on which an inequality relation between the smallest compressed state walk and a source state walk is established to search all the eligible compressed state walks. Then, by defining indistinguishable trajectories and utilizing the semitensor product approach, some matrix-based conditions for the solvability of lossless state compression ...
• Adaptive Synchronization of Uncertain Underactuated Euler-Lagrange Agents AI翻译

  摘要：This article proposes a framework for adaptive synchronization of uncertain underactuated Euler-Lagrange (EL) agents. The designed distributed controller can handle both state-dependent uncertain system dynamics terms and state-dependent uncertain interconnection terms among neighboring agents. No structural knowledge of such terms is required other than the standard properties of EL systems (positive definite mass matrix, bounded gravity, velocity-dependent friction bound, etc.). The study of...
• A Lyapunov--Krasovskii Method for Semiglobal Stabilization of a Class of Time-Delay Nonlinear Systems With Uncontrollable Linearization by Linear Feedback AI翻译

  摘要：This article presents a seemingly surprising yet simple solution to the open problem of when and how time-delay nonlinear systems with uncontrollable linearization is stabilizable by linear feedback. We show that if a less aggressive control objective, namely, semiglobal asymptotic stabilization (SGAS) instead of GAS is sought, instantaneous linear state feedback would be sufficient for the control of a class of nonlinear systems with state delays, despite the lack of local exponential stabili...
• Small-Gain Theorem for Safety Verification Under High-Relative-Degree Constraints AI翻译

  摘要：This article develops a small-gain technique for the safety analysis and verification of interconnected systems with high-relative-degree safety constraints. To this end, a high-relative-degree input-to-state safety (ISSf) approach is proposed to quantify the influence of external inputs on the subsystem safety. With a coordination transformation, the relationship between ISSf barrier functions (ISSf-BFs) and the existing high-relative-degree (or high-order) barrier functions is established to...
• Strong Consistency and Rate of Convergence of Switched Least Squares System Identification for Autonomous Markov Jump Linear Systems AI翻译

  摘要：In this article, we investigate the problem of system identification for autonomous Markov jump linear systems (MJS) with complete state observations. We propose switched least squares method for identification of MJS, show that this method is strongly consistent, and derive data-dependent and data-independent rates of convergence. In particular, our data-independent rate of convergence shows that, almost surely, the system identification error is ( O root log (T)/(T) where T is the time horiz...
• Geometric Characterization of the H-Property for Step-Graphons AI翻译

  摘要：In a recent article (Belabbas et al., 2022), we have exhibited a set of conditions that are necessary for the $H$-property to hold for the class of step-graphons. In this article, we prove that these conditions are essentially sufficient.
• Data-Driven Observability Analysis for Nonlinear Stochastic Systems AI翻译
  作者：Massiani, Pierre-Francois; Buisson-Fenet, Mona; Solowjow, Friedrich; Di Meglio, Florent; Trimpe, Sebastian

  摘要：Distinguishability and, by extension, observability are key properties of dynamical systems. Establishing these properties is challenging, especially when no analytical model is available and they are to be inferred directly from measurement data. The presence of noise further complicates this analysis, as standard notions of distinguishability are tailored to deterministic systems. In this article, we build on distributional distinguishability, which extends the deterministic notion by compar...
• Flexible Single-Link Manipulators Control Based on a Full-Order Transfer Function Model AI翻译
  作者：Mohsenipour, Reza; Liu, Guangjun
  作者单位：Toronto Metropolitan University; University of Cambridge
  摘要：This article presents a solution for the problem of flexible single-link robotic manipulators control in the frequency domain based on a full-order transfer function model. A transfer function model is derived from the partial differential equations of the flexible single-link manipulator system without any model order reduction. Conditions are obtained for the stability of the derived model that takes into account the payload mass changes. Employing these conditions, desired regions are obtai...
• Adaptive Synchronization of Complex Dynamical Networks: Dealing With Uncertain Impulses AI翻译

  摘要：The synchronization problem of complex dynamical networks with impulsive effects has been extensively addressed. However, great challenges arise when applying the existing synchronization criteria to networks with uncertain impulses. In this article, we investigate the adaptive synchronization problem of complex networks with uncertain impulses. First, the adaptive control gain is proved to be bounded for both synchronizing and desynchronizing impulses. Then, adaptive synchronization criteria ...
• Event-Triggered Dynamic Quantization for Nonlinear Systems With One-Bit Data Transmission AI翻译

  摘要：In this article, we study the problem of output feedback control for nonlinear systems under event-triggered implementation and dynamic quantization. We focus on the case where the initial output measurement is unknown and we propose a novel dynamic quantization policy to capture the output in a finite time. Next, the event-triggering mechanism that we design relies on a dynamic variable, which allows for reducing the amount of transmissions over the network. The dynamic quantizer is binary in...
