  摘要：In this article, we address the problem of global sampled-data output feedback stabilization for a class of nonlinear uncertain systems with delayed output using the continuous-discrete method. Thanks to the prediction technique and feedback domination method, a novel coupled design method of predictor-based continuous-discrete observer and linear controller is proposed when only delayed sampled-data output is accessible. The proposed predictor-based observer can effectively estimate the unkno...

  摘要：In this technical article, we analyze the performance improvement and optimality properties of the learning model predictive control (LMPC) strategy for linear deterministic systems. The LMPC framework is a policy iteration scheme where closed-loop trajectories are used to update the control policy for the next execution of the control task. We show that, when a linear independence constraint qualification (LICQ) condition holds, the LMPC scheme guarantees strict iterative performance improvem...
• Intermittent Static Output Feedback Control for Stochastic Delayed-Switched Positive Systems With Only Partially Measurable Information AI翻译
  作者：Ding, Kui; Zhu, Quanxin
  作者单位：Hunan Normal University
  摘要：This article is concerned with the L-1-stabilization of switched positive systems with stochastic interval delay by using an intermittent static output feedback control strategy. Different from previous results, this article mainly focuses on the system state, which is not only completely measurable due to external disturbance and sensor fault, rather than the result of continuous and complete measurement of the system, which is more in line with the actual system situation, but it also yields...
• LQG Graphon Mean Field Games: Analysis via Graphon-Invariant Subspaces AI翻译
  作者：Gao, Shuang; Caines, Peter E.; Huang, Minyi
  作者单位：McGill University; Carleton University
  摘要：This article studies approximate solutions to large-scale linear quadratic stochastic games with homogeneous nodal dynamics' parameters and heterogeneous network couplings within the graphon mean field game framework. A graphon time-varying dynamical system model is first formulated to study the finite and then limit problems of linear quadratic Gaussian graphon mean field games (LQG-GMFGs). The Nash equilibrium of the limit problem is then characterized by two coupled graphon time-varying dyn...
• Speeding-Up Backpropagation of Gradients Through the Kalman Filter via Closed-Form Expressions AI翻译

  摘要：In this article, we provide novel closed-form expressions enabling differentiation of any scalar function of the Kalman filter's outputs with respect to all its tuning parameters and to the measurements. The approach differs from the previous well-known sensitivity equations in that it is based on a backward (matrix) gradient calculation, which leads to drastic reductions in the overall computational cost. It is our hope that practitioners seeking numerical efficiency and reliability will bene...
• Event-Triggered Control for Nonlinear Uncertain Systems via a Prescribed-Time Approach AI翻译
  作者：Ning, Pengju; Hua, Changchun; Li, Kuo; Meng, Rui
  作者单位：Yanshan University
  摘要：The event-triggered control problem is investigated for nonlinear uncertain systems via a prescribed-time approach. Different from the existing event-triggered control methods that can only achieve bounded or finite-time stability, this article focuses on the prescribed-time stability under the event-based design method. First, a novel prescribed-time stability criterion is presented, which provides explicit theoretical supports and systematic guidelines for addressing the studied problem. The...
• Quantum Robust Optimal Control for Linear Complex Quantum Systems With Uncertainties AI翻译
  作者：Wang, Shi; Ding, Chao; Fang, Qiu; Wang, Yaonan
  作者单位：Hunan University
  摘要：The aim of this note is to study the quantum robust optimal control problem for a class of linear quantum systems with uncertainties. It is shown that such problem can be converted into a mixed linear quadratic Gaussian and H-infinity quantum control problem. A physical model described by complex quantum stochastic differential equations (CQSDEs) is presented for the quantum system with uncertainties. The quantum system described by CQSDEs is called a complex quantum system in terms of annihil...
• Adaptive Finite-Time Tracking Control of Nonlinear Systems With Dynamics Uncertainties AI翻译

  作者单位：Bohai University; Beijing Jiaotong University; Northeastern University - China
  摘要：In this article, the problem of adaptive backstepping finite-time tracking control is investigated for a class of strict-feedback nonlinear systems with unmodeled dynamics and dynamic disturbances. A modified finite-time dynamic signal is first introduced to dominate the dynamic disturbance. By using the adaptive control, backstepping technique, and finite-time stability theory, an adaptive finite-time tracking controller is developed. Under the proposed control scheme, the finite-time trackin...

  摘要：This article addresses the problem of achieving and maintaining the 2-D/3-D formation shape of networked manipulator end effectors. We first present a distributed formation controller for manipulators whose system parameters are perfectly known. The formation control objective is achieved by assigning virtual springs between end effectors and by adding damping terms at joints, which provides a clear physical interpretation of the proposed solution. Subsequently, we extend it to the case where ...

  摘要：For many stochastic hybrid systems in the real world, it is inappropriate to study if their solutions will converge to an equilibrium state (say, 0 by default) but more appropriate to discuss if the probability distributions of the solutions will converge to a stationary distribution. The former is known as the asymptotic stability of the equilibrium state while the latter the stability in distribution. This article aims to determine whether or not a stochastic state feedback control can make ...
