  摘要：This article explores the automatic verification of bounded synchronization for heterogeneous polynomial networked systems (HPNSs) with polynomial coupling function. In our method, the generalized blended dynamics is presented to analyze the heterogeneity of systems. By utilizing polynomial Lyapunov functions, the synchronization criterion for HPNSs under directed topology is presented, along with a bounded set where the synchronization errors of HPNSs reside when the time progresses towards i...
• Output Feedback-Based Adaptive Optimal Output Regulation for Continuous-Time Strict-Feedback Nonlinear Systems AI翻译

  摘要：This article investigates the optimal output regulation problem for continuous-time strict-feedback nonlinear systems, in which the full states are not measurable in real-time, and a priori knowledge of system dynamics and an admissible control policy are both unavailable. Fundamental challenges here differing from existing works are twofold: 1) only output data rather than full state data are available; 2) policy iteration cannot be performed since admissible control policy is not available. ...

  摘要：In this article, we address a coordination-control problem of multiagent systems with various types of relative measurements in a unified way. To this end, we express relative measurements in the agents' own frames using the frame transformation introduced in this article. This transformation is expressed with a subset of semidirect products, and it describes different types of practical measurement information, such as uncertain measurements in positions and bearings. Second, a distributed co...

  摘要：This article proposes a novel state estimation strategy with globalized robustness for a class of systems under uncertainty. Departing from the classical minimax estimation, this article focuses on the globalized robust estimation (GRE), which minimizes the estimator's fragility to attain an acceptable loss compared with the nominal model. The GRE problem has an easily specified hyperparameter as compared to the maximal radius in the classical minimax estimation. Besides, it considers all poss...
• Global Exponential Stability Preservation Under Sampling and Approximated Delay-Dependent Feedbacks for Nonlinear Systems With Time-Varying Delays AI翻译

  摘要：This manuscript shows the global exponential stability preservation for the class of fully nonlinear retarded globally Lipschitz systems with time-varying delays under suitably fast sampling while considering at the same time the problem of the nonavailability in the buffer device of the system variables at some past (delayed) times. To this aim, a spline interpolation scheme is exploited to derive the digital control law, which has the benefit of ease of implementation. Main theoretical resul...

  摘要：Rapid advancements of artificial neural networks for computer sciences, inspired by biological neuron interaction mechanisms, may be leveraged in reverse to synthetic biology by providing advanced molecular programming paradigms capable of autonomously learning and executing complex tasks. A challenging exploration is to implement neural network functionalities through biochemical reaction networks (BCRNs), a language that is inherently compatible with in vivo, with difficulties especially in ...
• Distributed Resilient Interval Observer Synthesis for Nonlinear Discrete-Time Systems AI翻译

  摘要：This article introduces a novel recursive distributed estimation algorithm aimed at synthesizing input and state interval observers for nonlinear bounded-error discrete-time multiagent systems. The considered systems have sensors and actuators that are susceptible to unknown or adversarial inputs. To solve this problem, we first identify conditions that allow agents to obtain nonlinear bounded-error equations characterizing the input. Then, we propose a distributed interval-valued observer tha...
• Chance Constrained Mobile Robot Trajectory Optimization in Partially Known Environments AI翻译
  作者：Liu, Tianhao; Chai, Runqi; Chen, Kaiyuan; Carrasco, Joaquin; Lennox, Barry

  摘要：This article studies a mobile robot trajectory optimization problem where the control path constraints are affected by stochastic parameters and the obstacle information is limited. Based on online measured data, an upper confidence bound (UCB) is designed such that the estimated obstacle regions are guaranteed to cover the real obstacles with a predefined probability, thus avoiding collisions. Using the proposed approach, the control path constraints are transformed into deterministic constra...
• Robustness and Scalability of Consensus Networks: The Role of Memory Information AI翻译
  作者：Wang, Jiamin; Liu, Jian; Xiao, Feng; Zheng, Yuanshi
  作者单位：Xidian University; North China Electric Power University
  摘要：It has been reported that local memory information could enhance certain consensus performance of multiagent networks, such as protecting privacy and accelerating consensus. This article aims to investigate whether memory information can improve the robustness and scalability of consensus networks. The robustness is measured by the & ell;(2) gains from disturbances to consensus errors, and the scalability means that consensus can be preserved without retuning control parameters as the network ...
• New Method for SISO Strong Stabilization With Advantages Over Nevanlinna-Pick Interpolation AI翻译

  摘要：Linear time-invariant single-input single-output (SISO) systems which satisfy a parity interlacing property (PIP) can be stabilized with a stable controller in a single feedback loop. We consider such stabilization of plants with rational transfer functions of relative degree 0, 1, or 2. Finding such controllers requires an interpolant U(s) with specific properties. Existing methods for finding U(s) use an iterative manual calculation or, when the plant's right half plane zeros are simple, a m...
