• Simultaneous Arrival to Origin Convergence: Sliding-Mode Control Through the Norm-Normalized Sign Function AI翻译
  作者：Li, Dongyu; Ge, Shuzhi Sam; Lee, Tong Heng

  摘要：In this article, simultaneous arrival to origin (SATO) convergence is defined-all state elements arriving at the origin at the same time. Accordingly, a relevant sufficient condition is proposed for SATO convergence. Based on this formulation of SATO convergence, the classical and norm-normalized (NN) sign functions are revisited. Their differences are studied with applications in sliding-mode control design. Both functions (expectedly when properly invoked) contribute to system stability, whi...

  摘要：For a class of generalized Persidskii systems, whose dynamics are described by superposition of a linear part with multiple sector nonlinearities and exogenous perturbations, the conditions of practical stability, instability, and oscillatory behavior in the sense of Yakubovich are established. For this purpose, the conditions of local instability at the origin and global boundedness of solutions (practical input-to-state stability) are developed in the form of linear matrix inequalities. The ...
• Automatic Trajectory Synthesis for Real-Time Temporal Logic AI翻译

  摘要：Many safety-critical systems, such as autonomous vehicles and service robots, must achieve high-level task specifications with performance guarantees. Much recent progress toward this goal has been made through an automatic controller synthesis from temporal logic specifications. Existing approaches, however, have been limited to relatively short and simple specifications. Furthermore, existing methods either consider some prior discretization of the state space, deal only with a convex fragme...

  摘要：This article considers balanced truncation of discrete-time Hankel k-positive systems, characterized by Hankel matrices whose minors up to order k are nonnegative. Our main result shows that if the truncated system has order k or less, then it is Hankel totally positive (8-positive), meaning that it is a sum of first-order lags. This result can be understood as a bridge between two known results: the property that the first-order truncation of a positive system is positive (k = 1), and the pro...
• Observer Design for a Class of Semilinear Hyperbolic PDEs With Distributed Sensing and Parametric Uncertainties AI翻译
  作者：Holta, Haavard; Aamo, Ole Morten
  作者单位：Norwegian University of Science & Technology (NTNU)
  摘要：We study a class of heterodirectional semilinear hyperbolic partial differential equations, where the distributed state vector is partially measured. An observer estimating the unmeasured part of the state vector is designed. The design is, for instance, applicable to multiphase 1-D fluid models, where the pressure is measured, but the distributed flow and phase concentrations are not. Furthermore, the observer is extended to systems with parametric uncertainties appearing in the dynamics of t...
• Input Delay Tolerance of Nonlinear Systems Under Smooth Feedback: A Semiglobal Control Framework AI翻译
  作者：Wang, Yuanjiu; Lin, Wei

  摘要：This article studies the problem of when a globally asymptotically stabilizable nonlinear system by smooth feedback is tolerable with respect to input delay. We illustrate, by means of theoretic and practical examples, some fundamental limitations including: 1) A globally exponentially stabilizable (GES) nonlinear system may not guarantee global asymptotic stabilizability (GAS) of the nonlinear system even with an arbitrarily small input delay; 2) GAS cannot even ensure semiglobal asymptotic s...
• Distributed Model Predictive Control for Tracking: A Coalitional Clustering Approach AI翻译
  作者：Chanfreut, Paula; Maestre, Jose Maria; Ferramosca, Antonio; Muros, Francisco Javier; Camacho, Eduardo F. F.
  作者单位：University of Sevilla; University of Bergamo
  摘要：In this article, a coalitional robust model predictive controller for tracking target sets is presented. The overall system is controlled by a set of local control agents that dynamically merge into cooperative coalitions or clusters so as to attain an efficient tradeoff between cooperation burden and global performance optimality. Within each cluster, the agents coordinate their inputs to maximize their collective performance, while considering the coupling effect with external subsystems as ...
• Degeneracy-Free Particle Filter: Ensemble Kalman Smoother Multiple Distribution Estimation Filter AI翻译
  作者：Murata, Masaya; Kawano, Isao; Inoue, Koichi
  作者单位：Japan Aerospace Exploration Agency (JAXA)
  摘要：We propose the ensemble Kalman smoother multiple distribution estimation filter (EnKS-MDEF) for nonlinear state estimation problems. The EnKS-MDEF is an example of the multiple distribution estimation filter (MDEF), which is a particle filter (PF) that estimates the filtered state probability density function (pdf) using multiple conditional state pdfs. The one step behind (OSB) smoothed state pdf used for calculating the filtered state pdf of the MDEF is approximated by the ensemble Kalman sm...
• Finite-Memory Supervisory Control of Discrete Event Systems for LTL[F] Specifications AI翻译
  作者：Sakakibara, Ami; Urabe, Natsuki; Ushio, Toshimitsu
  作者单位：Sapienza University Rome; University of Osaka; Max Planck Society
  摘要：In this article, we study a supervisory control problem under a constraint on memory size as well as a constraint described by a class of quantitative linear temporal logic, which enables us to consider how well the specification is satisfied. Our control objective is to design a finite-memory supervisor such that the satisfaction value of the specification formula on the controlled system is larger than or equal to a given threshold. We adopt a Safraless synthesis methodology and reduce the p...
• Finite-Time Composite Disturbance Rejection Control for Discrete-Time Markovian Jump Systems AI翻译
  作者：Zhang, Jinhui; Wu, Zheng-Guang; Xia, Yuanqing
  作者单位：Beijing Institute of Technology; Zhejiang University; Chengdu University
  摘要：In this article, the compositedisturbance rejection control approach is established for discrete-time Markovian jump systems with unknown external disturbance. With the transformed system in the regular form, a new mode-dependent disturbance observer is proposed to estimate the unknown disturbance in the absence of the exosystem of the disturbance. Then, the chattering-free controller is designed in the backstepping framework, and the disturbance estimate is incorporated to achieve active dist...
