• Control Barrier Functions for Stochastic Systems and Safety-Critical Control Designs AI翻译
  作者：Nishimura, Yuki; Hoshino, Kenta
  作者单位：Kagoshima University; Kyoto University
  摘要：In recent years, the analysis of a control barrier function has received considerable attention because it is helpful for the safety-critical control required in many control application problems. While the extension of the analysis to a stochastic system studied by many researchers, it remains a challenging issue. In this article, we consider sufficient conditions for reciprocal and zeroing control barrier functions ensuring safety with probability one and design a control law using the funct...

  摘要：A cascade connection comprising a delay, a partial differential equation (PDE), and an ordinary differential equation (ODE) is referred to as distributed if an integral operator of the functional state of the delay or the PDE enters, as a scalar, the next system in the cascade, or if the ODE state acts as an input to the PDE throughout the PDE's domain. While boundary control of systems involving PDEs or delays typically calls for the PDE backstepping approach, such distributed interconnection...
• An Adaptive Distributed Observer for a Class of Uncertain Linear Leader Systems Over Jointly Connected Switching Networks and Its Application AI翻译

  摘要：The early results on the adaptive distributed observer for uncertain leader systems have three limitations. The adaptive distributed observer is state-based, the communications among the follower subsystems are undirected, and the communication network is static. Despite years of efforts, these issues have not been fully addressed. In this article, we develop an output-based adaptive distributed observer for a class of uncertain linear leader systems over jointly connected switching networks. ...
• Prescribed-Time Observer Design for Nonlinear Triangular Systems With Delayed Measurements AI翻译

  摘要：In this article, we propose a prescribed-time observer for nonlinear triangular systems with delayed outputs. The proposed observer is endowed with prescribed-time stability and relies on a scaling function and Lyapunov-Razumikhin-based conditions. We establish that the observer design derives a delay-independent stability condition in terms of linear matrix inequalities that guarantees prescribed-time convergence to zero of the estimation error. Additionally, we derive an explicit relation be...
• Static Output Energy-to-Peak Control for Semi-Markov Jump Linear Systems With Phase-Type Distributions and Hidden Modes AI翻译

  摘要：This article studies the L-2-L-infinity (also known as energy-to-peak) static output feedback control for continuous-time semi-Markov jump systems, with the jump times modeled through phase-type distributions. It is also assumed that the post-jump state variable of the semi-Markov model is not directly accessible and the controller has only access to an observed process related to this variable. The goal is to provide sufficient conditions for the design of static output feedback controllers s...
• Chaotic Chattering in Sliding Mode Control Systems AI翻译

  摘要：Chattering in sliding mode (SM) control is known as fast self-excited periodic motions (oscillations) that occur due to the combination of two factors: nonlinearities that are not Lipschitz continuous and additional dynamics of actuators and sensors (the dynamics not accounted for in SM control system design). It is found in the present research that under certain combinations of parameters of the discontinuous homogeneous SM controller and actuator, the chattering is manifested not as periodi...
• Distributed Nash Equilibrium Seeking for Constrained Multicluster Games of Second-Order Nonlinear Multiagent Systems AI翻译
  作者：Deng, Zhenhua; Chen, Tao
  作者单位：Central South University
  摘要：This article investigates multicluster games (MCGs) of multiagent systems, where the players are subject to nonlinear inequality constraints. In contrast to existing MCGs, our problem involves the second-order nonlinear dynamics of players. Due to the second-order nonlinear dynamics, existing Nash equilibrium (NE) seeking algorithms cannot deal with our problem. Also, the second-order nonlinear dynamics and the nonlinear inequality constraints make it difficult to design and analyze distribute...
• Innovation-Based Remote State Estimation Secrecy With No Acknowledgments AI翻译
  作者：Kennedy, Justin M.; Ford, Jason J.; Quevedo, Daniel E.; Dressler, Falko
  作者单位：Queensland University of Technology (QUT); Technical University of Berlin
  摘要：Secrecy encoding for remote state estimation in the presence of adversarial eavesdroppers is a well studied problem. Typical existing secrecy encoding schemes rely on the transmitter's knowledge of the remote estimator's current performance. This performance measure is often shared via packet receipt acknowledgments. However, in practical situations the acknowledgment channel may be susceptible to interference from an active adversary, resulting in the secrecy encoding scheme failing. Aiming t...
• An Internal Model Approach to Cooperative Output Regulation Over Switching Graphs AI翻译
  作者：Koru, Ahmet Taha; Sarsilmaz, Selahattin Burak; Kartal, Yusuf; Lewis, Frank L.; Yucelen, Tansel; Muse, Jonathan A.; Davoudi, Ali

  摘要：This article considers the cooperative output regulation problem of heterogeneous linear time-invariant multiagent systems over switching graphs. A sufficient condition for an internal model-based distributed dynamic state feedback control law to solve this problem is the asymptotic stability of the origin of the unforced switched closed-loop system under graph-theoretic and algebraic assumptions. Notably, the asymptotic stability depends on the properties of the switching signal. To this end,...
• Zonotope-Based Symbolic Controller Synthesis for Linear Temporal Logic Specifications AI翻译

  摘要：This article studies the controller synthesis problem for nonlinear control systems under linear temporal logic (LTL) specifications using zonotope techniques. A local-to-global control strategy is proposed for the desired specification expressed as an LTL formula. First, a novel approach is developed to divide the state space into finite zonotopes and constrained zonotopes, which are called cells and allowed to intersect with the neighbor cells. Second, from the intersection relation, a graph...
