  摘要：This article provides a nonsingular predefined-time terminal sliding mode control scheme for perturbed chains of integrators. Based on the linear delayed feedback technique, a class of nonsingular smooth prescribed-time sliding surfaces with artificial time-delays is constructed, and the control scheme can achieve predefined-time control for perturbed chains of integrators with matched and mismatched disturbances. Especially, for double integrators, an initial-condition-based sufficient condit...

  摘要：This article investigates the online identification problem of binary-valued moving average systems. A stochastic approximation-based algorithm without projections or truncations is proposed. To analyze the convergence property of the algorithm, the distribution tail of the parameter estimate is proved to be exponentially convergent through an auxiliary stochastic process. Under uniform persistent excitations, the almost sure and mean square convergence of the algorithm is obtained. When the s...
• Robust Recursive Regulator for Polytopic Markovian Jump Linear Systems With Random State Delays AI翻译

  摘要：The control problem of dynamic systems that undergo sudden changes and rely on past data is known to be challenging to solve and has received a lot of attention in the past years. Meanwhile, the optimal control theory has been widely used to develop efficient conditions for stability analysis and control synthesis. In this article, we propose a robust regulation strategy for Markovian jump linear systems subject to delayed states and polytopic uncertainties. The time-varying delay belongs to a...

  摘要：This article tackles the predefined-time control problem for nonlinear systems subject to preassigned performance metrics (PPMs) and state constraints. To meet the PPMs and state constraints, the preassigned performance control-based barrier Lyapunov functions are designated to acquire the performance metrics and the satisfaction of state constraints. The proposed control approach combines the predefined-time control with the recursive design of command-filter backstepping to achieve the prese...
• Nonexistence of Upper Bound to Inferencing Level in Decentralized Discrete Event Control AI翻译

  摘要：In the authors' earlier work, the notion of inference-observability was introduced to characterize the existence of decentralized supervisors that perform multilevel inferencing against self-ambiguity and the ambiguities of others to jointly arrive at a correct control decision. When the property of $N$-inference-observability holds, $N$-levels of inferencing are needed. We show in this article that the class of $N$-inference-observable languages increases strictly monotonically as the paramet...
• Distributed Optimal Consensus Control of Constrained Multiagent Systems: A Nonseparable Optimization Perspective AI翻译

  摘要：The optimal consensus control problem of constrained multiagent systems is studied in this article. Considering the transient performance, the final consensus state and constraints simultaneously, the problem is formulated as a constrained nonseparable optimization problem accounting for the control inputs and the final consensus state. A distributes hybrid gradient projection alternating direction method of multipliers is designed to separate the coupled problem to independent subproblems sol...

  摘要：In this article, the robust quantized sampled-data tracking control problem of nonlinear systems affected by actuation disturbances and observation errors is studied. In particular, results concerning the robustification and the quantized sampled-data implementation of tracking controllers are provided for nonlinear systems in control-affine form. Inspired by the well-known notion of steepest descent feedbacks, the novel notion of steepest tracking feedback (STF) is introduced and the input-to...
• Stability of Asynchronous Networked Linear Control Systems With Direct-Feedthrough Terms and Scheduling Protocols AI翻译
  作者：Guo, Ziyi; Yu, Hao; Chen, Tongwen
  作者单位：University of Alberta; Beijing Institute of Technology
  摘要：In this article, we analyze the stability of a linear control system where the plant and controller, both containing direct-feedthrough terms, communicate asynchronously over a network using scheduling protocols. The overall system is modeled as a hybrid dynamical system and sufficient conditions for its closed-loop stability are derived using a new Lyapunov function. Additionally, we define a stability property that is associated with the feedthrough terms and the adopted scheduling protocols...
• Optimal Steady-State Regulation by State Feedback AI翻译
  作者：Hafez, Mohamed A.; Uzeda, Erick Mejia; Broucke, Mireille E.
  作者单位：University of Toronto
  摘要：This article formulates the optimal steady-state regulation (OSSR) problem. In addition to asymptotic stability and regulation, the problem includes a cost on maintaining steady-state inputs and outputs to controllers contributing to regulation, contrasting with standard optimal steady-state problems that only include a cost on the steady-state inputs and outputs of the plant. Motivated by applications in neuroscience, we develop a two-timescale adaptive control architecture to solve a specifi...

  摘要：This article deals with the existence and robust stability of hybrid limit cycles for a class of hybrid systems given by the combination of continuous dynamics on a flow set and discrete dynamics on a jump set. For this purpose, the notion of Zhukovskii stability, typically stated for continuous-time systems, is extended to the hybrid systems. Necessary conditions, particularly, a condition using a forward invariance notion, for existence of hybrid limit cycles are first presented. In addition...
