摘要：In this article, we address the problem of exponential mean-square stabilization control for cyber-physical systems (CPSs) characterized by time-varying parameters, random denial-of-service (DoS) attacks, and transmission delay. The motivation arises from the increasing complexity and vulnerability of CPSs, which are prone to various networked challenges, including random DoS attacks and transmission delays. In addition, the presence of time-varying parameters further exacerbates the difficult...

摘要：Projected dynamical systems (PDSs) form a class of discontinuous constrained dynamical systems, and have been used widely to solve optimization problems and variational inequalities. Recently, they have also gained significant attention for control purposes, such as high-performance integrators, saturated control, and feedback optimization. In this work, we establish that locally Lipschitz continuous dynamics, involving Control Barrier Functions (CBFs), namely, CBF-based dynamics, approximate ...

摘要：The framework of integral quadratic constraints is used to perform an analysis of gradient descent with varying step sizes. Two performance metrics are considered: convergence rate and noise amplification. We assume that the step size is produced from a line search and varies in a known interval. Modeling the algorithm as a linear parameter-varying (LPV) system, we construct a parameterized linear matrix inequality condition that certifies algorithm performance, which is solved using a result ...

摘要：Practical control applications frequently require state and input constraints. Even more, certain applications may require the controller to fit with a strict time scheduling. In this context, this article proposes a control scheme that ensures convergence to the origin in prescribed-time for both linear controllable systems and nonlinear systems in the normal form, under nonvanishing disturbances. In this, the settling time is an explicit parameter given by the designer. Moreover, a planning ...

摘要：We present a method to design a state-feedback controller ensuring exponential stability for nonlinear systems using only measurement data. Our approach relies on Koopman-operator theory and uses robust control to explicitly account for approximation errors due to finitely many data samples. To simplify practical usage across various applications, we provide a tutorial-style exposition of the feedback design and its stability guarantees for single-input systems. Moreover, we extend this contro...

摘要：This article introduces output prediction methods for two types of systems containing sinusoidal-input uniformly convergent (SIUC) elements. The first method considers these elements in combination with single-input single-output linear time-invariant (LTI) systems before, after, and in parallel to them. The second method considers a multiple-input multiple-output LTI system where each input is controlled by an SIUC element. The output prediction only requires frequency-response functions of t...

摘要：This article proposes a unifying design framework for dynamic feedback controllers that track solution trajectories of time-varying generalized equations, such as local minimizers of nonlinear programs or competitive equilibria (e.g., Nash) of noncooperative games. Inspired by the feedback optimization paradigm, the core idea of the proposed approach is to repurpose classic iterative algorithms for solving generalized equations (e.g., Josephy-Newton, forward-backward splitting) as dynamic feed...

摘要：This article considers a distributed Thompson sampling algorithm for a cooperative multiplayer multiarmed bandit problem. We consider a multiagent system in which each agent pulls an arm according to consensus-based Bayesian inference with probability matching. To estimate the reward probability of each arm, a group of agents shares the observed rewards with neighboring agents in a communication graph. Following the information exchange, each agent updates the estimation of the posterior distr...

摘要：The fragile common pool of resource (CPR) game is an instance of a resource sharing game where a common resource, which is prone to failure due to overuse, is shared among several players. Players have a fixed initial endowment and are faced with the task of investing in the common resource without forcing it to failure. The return from the common resource is subject to uncertainty and stochasticity, and is perceived by the players in a prospect-theoretic manner based on their behavioral chara...

摘要：In this article, mean-square leader-following consensus for multiagent systems is considered. In particular, nonidentical channel fading is involved in the systems which makes the consensus problem much more difficult. To overcome the difficulty, a novel distributed consensus protocol is proposed containing the relative measurement information and a feedforward controller. By applying a parameterized Riccati inequality and defining a Lyapunov function, sufficient conditions for the leader-foll...
