摘要：Analyzing event-triggered control's (ETC) sampling behavior is of paramount importance, as it enables formal assessment of its sampling performance and prediction of its sampling patterns. In this work, we formally analyze the sampling behavior of stochastic linear periodic ETC (PETC) systems by computing bounds on associated metrics. Specifically, we consider functions over sequences of state measurements and intersampling times that can be expressed as average, multiplicative or cumulative r...

摘要：In this article, an approach is proposed for the remote observation of a dynamical system through a data-rate constrained communication channel. The focus is put on discrete-time systems with a Lipschitz nonlinearity, driven by an external signal, and subject to bounded state perturbation and measurement error. The problem at hand is providing estimates of system's state at a remote location, which is connected via a channel, which can only sent limited numbers of bits per unit of time. A solu...

摘要：This article presents a new sliding-mode control (SMC) design method for linear uncertain impulsive systems, where the sliding function is designed to be linear with a time-varying projection matrix. When the time-varying projection matrix satisfies a so-called continuity condition, the sliding function is continuous along the state trajectories, which will facilitate the analysis and design of SMC laws. To obtain a tractable design algorithm on the time-varying projection matrix, a regular fo...

摘要：In this work, we address the problem of designing a control law for a system in feedforward form to be globally incrementally exponentially stable. To do that, we develop an incremental version of the so-called forwarding mod {LgV} approach. Then, we apply such a control design to the problem of compensating matched disturbances assumed to be given by the superimposition of a finite number of harmonics with unknown amplitude. For this, we propose a dynamic controller made of L linear oscillato...

摘要：This article addresses the problem of distributed Nash equilibrium (NE) seeking in strongly contractive aggregative multipopulation games subject to partial-decision information. In particular, we consider the scenario where the so-called payoff providers of the multiple populations communicate through a possibly noncomplete network, and we formulate some consensuslike dynamics for the payoff providers to distributedly compute their payoff signals using local information only. Moreover, by exp...

摘要：Conditions are investigated in this article for uniquely determining parameters of a descriptor system from time-domain noise-free input/output data, in which system matrices depend on its parameters through a linear fractional transformation. This model includes networked dynamic systems as its special cases. A bilinear matrix equality-based necessary and sufficient condition has been derived, which can be verified in principle for a low-dimensional system. Moreover, a computationally attract...

摘要：This article investigates event-based fixed-time control problem for a class of uncertain high-order nonlinear systems. Different from existing event-triggered results, which can only achieve bounded or finite-time stability, this article studies on fixed-time stability, and unknown control coefficients are allowed in the system. To compensate uncertainties, an adaptive controller is designed with a switching parameter by utilizing adding a power integrator method. A logic switching rule is co...

摘要：This brief note corrects the statements of Theorem 5.1 and Corollary 5.2 in (Tabuada and Gharesifard, 2023). The main consequence of these corrections is that the width of residual neural networks that suffices for universal approximation changes from n+1 to 2n+1. This is consistent with recent observations made in (Hwang, 2023) regarding the use of neural networks to approximate functions by diffeomorphisms.

摘要：The optimal control issue of fast sampling singularly perturbed systems is discussed throughout this article. As a new attempt, without using complete system dynamics, the composite controller is designed by using controller of the different subsystems along with the usage of the subsystem decomposition technique by means of singular perturbation theory. Compared with the existing policy iteration and value iteration algorithms, there is no enforced requirement for a stabilizing control strate...

摘要：This article establishes a mathematical framework for discrete-time linear time-invariant systems to compare the optimal state estimation performance of the set-membership estimator, set-valued observer, and interval observer in the polytopic representation. First, the ability of observer gains in reducing the conservatism of state estimation sets is characterized by the support function. Second, the optimal estimation results given by the set-valued and interval observers are derived rigorous...
