• The Implicit Maximal Positively Invariant Set AI翻译
  作者：Rakovic, Sasa V.; Zhang, Sixing
  作者单位：Beijing Institute of Technology; Beijing Institute of Technology
  摘要：This article introduces an alternative characterization, together with indirect computation and implicit representation, of the maximal positively invariant set for the nonlinear dynamics and closed constraints. The introduced alternative characterization, indirect computation, and implicit representation of the maximal positively invariant set are novel features that, when combined together, overcome successfully dimensionality related limitations of the standard explicit computation of the m...

  摘要：This article proposes an event-triggered variational Bayesian filter for remote state estimation with unknown and time-varying noise covariances. After presetting multiple nominal process noise covariances and an initial measurement noise covariance, a variational Bayesian method and a fixed-point iteration method are utilized to jointly estimate the posterior state vector and the unknown noise covariances under a stochastic event-triggered mechanism. The proposed algorithm ensures low communi...
• Adaptive Tracking Control With Global Performance for Output-Constrained MIMO Nonlinear Systems AI翻译

  摘要：In this article, a novel adaptive tracking control technique is developed for multiple-input-multiple-output nonlinear systems with model uncertainty and under output constraints occurring in a limited time interval (OCOLT). The OCOLT, which is a type of constraints occurring sometime after (rather than the beginning of) system operation and with limited duration, can be found in many practical systems and has not been effectively addressed in the literature until now. By designing a new shift...
• Smoother Entropy for Active State Trajectory Estimation and Obfuscation in POMDPs AI翻译
  作者：Molloy, Timothy L.; Nair, Girish N.

  摘要：In this article, we study the problem of controlling a partially observed Markov decision process (POMDP) to either aid or hinder the estimation of its state trajectory. We encode the estimation objectives via the smoother entropy, which is the conditional entropy of the state trajectory given measurements and controls. Consideration of the smoother entropy contrasts with previous approaches that instead resort to marginal (or instantaneous) state entropies due to tractability concerns. By est...
• Reactive Symbolic Planning and Control in Dynamic Adversarial Environments AI翻译

  摘要：Satisfying both safety and reachability requirements in dynamic adversarial environments is very challenging, particularly when little or no information about the dynamics and intentions of the adversarial objects is available. Therefore, this article addresses the problem of path planning and control of autonomous vehicles in a dynamic adversarial reach-avoid scenario with two noncooperative vehicles and their competitive objectives: 1) reaching a target and avoiding the other vehicle for one...
• Robust Uncertainty Bounds in Reproducing Kernel Hilbert Spaces: A Convex Optimization Approach AI翻译

  摘要：The problem of establishing out-of-sample bounds for the values of an unknown ground-truth function is considered. Kernels and their associated Hilbert spaces are the main formalism employed herein, along with an observational model where outputs are corrupted by bounded measurement noise. The noise can originate from any compactly supported distribution, and no independent assumptions are made on the available data. In this setting, we show how computing tight, finite-sample uncertainty bound...
• Resource-Aware Discretization of Accelerated Optimization Flows: The Heavy-Ball Dynamics Case AI翻译
  作者：Vaquero, Miguel; Mestres, Pol; Cortes, Jorge

  摘要：This article proposes a methodology for discretizing accelerated optimization flows while retaining their convergence properties. Inspired by the success of resource-aware control in developing efficient closed-loop feedback implementations on digital systems, we view the last sampled state of the system as the resource to be aware of. We illustrate our design methodology for discretization on a newly introduced continuous-time dynamics, the heavy-ball dynamics with displaced gradient. Our alg...
• Using Memoryless Output Feedback to Semiglobally Stabilize a Class of SISO Nonlinear Systems With Input Delay AI翻译
  作者：Lin, Wei; Sun, Jiwei
  作者单位：University System of Ohio; Case Western Reserve University
  摘要：Using the semiglobal control idea from the recent work (Wang and Lin, 2022), we present a different semiglobal method without invoking the dynamic extension technique to prove that in the single-input-single-output (SISO) case, certain nonaffine systems with input delay are semiglobally asymptotically stabilizable (SGAS) via n-dimensional memoryless output feedback. A dynamic output compensator is constructed and composed of an n-dimensional nonlinear observer and an observer-based controller,...

  摘要：This article introduces a closed-loop frequency analysis tool for reset control systems. To begin with sufficient conditions for the existence of the steady-state response for a closed-loop system with a reset element and driven by periodic references are provided. It is then shown that, under specific conditions, such a steady-state response for periodic inputs is periodic with the same period as the input. Furthermore, a framework to obtain the steady-state response and to define a notion of...
• Fixed-Time Consensus Tracking for Multi-Agent Systems With a Nonholomonic Dynamics AI翻译

  摘要：In this article, we investigate the control strategy of fixed-time leader-following consensus for chained-form systems with matched disturbances. A new decentralized observer is designed under a directed topology to estimate the leader state in a fixed time for each follower. Then, a novel control protocol is developed to track the estimated leader state in a prescribed finite time. Different from existing results, the bound we derive for the setting time does not depend on the initial conditi...
