摘要:We consider functional regression models with noisy outputs resulting from linear transformations. In the setting of regularization theory in reproducing kernel Hilbert spaces (RKHSs), much work has been devoted to build uncertainty bounds around kernel-based estimates, hence characterizing their convergence rates. Such results are typically formulated using either the average squared loss for the prediction or the RKHS norm. However, in signal processing and in emerging areas, such as learnin...

摘要:In this article, we propose a novel event-triggered distributed privacy-preserving consensus scheme for linear continuous-time multiagent systems, which can be divided into three phases. First, for each agent, an event-triggered mechanism is designed to determine whether the current state is transmitted to the corresponding neighbor agents. Then, to protect the privacy of initial states from disclosure, the edge-based mutually independent standard white noise is added to each communication cha...

摘要:A general problem encompassing output regulation and pattern generation can be formulated as the design of controllers to achieve convergence to a persistent trajectory within the zero dynamics on which an output vanishes. We develop an optimal control theory for such design by adding the requirement to minimize theH2norm of a closed-loop transfer function. Within the framework of eigen structure assignment, the optimal control is proven identical to the standard H-2 control in form. However, ...

摘要:The present article proposes a general framework for the analysis of constraints satisfaction with respect to the trajectories of a dynamical system. The results are presented in a discrete-time framework and pertain to the class of set-theoretic methods. The main objective is to go beyond the state of the art by characterizing the intermittent constraint satisfaction along the evolution of the trajectories of a dynamical system. Two relaxed notions are introduced in this sense, one characteri...

摘要:A novel discontinuous observer design for nonlinear systems, whether stable or not, is presented in this article; it removes former limitations on matching and minimum-phase conditions, Lipschitz bounds, and linearity of outputs. Based on a pair of diffeomorphisms an observer error system can be written whose nonlinear nominal model depends entirely on the error, input, and output signals, thus allowing error-dependent domains of attraction where unstable signals are estimated. Nonlinear nomin...

摘要:Output feedback control of switched nonlinear planar systems (SNPSs) with quantized after being sampled information under arbitrary switchings is mainly investigated. Output signals are sampled by meticulously constructed switched dynamic event-triggered mechanisms (SDE-TMs). Then, the sampled information is further quantized by logarithmic quantizer, transmitted by network and converted to analog signals by a zero-order holder. Just leveraging this quantized-after-sampled information, switche...

摘要:This article introduces a decentralized state-dependent Markov chain synthesis (DSMC) algorithm for finite-state Markov chains. We present a state-dependent consensus protocol that achieves exponential convergence under mild technical conditions, without relying on any connectivity assumptions regarding the dynamic network topology. Utilizing the proposed consensus protocol, we develop the DSMC algorithm, updating the Markov matrix based on the current state while ensuring the convergence cond...

摘要:We show that a recent dissipativity approach to feedback stability analysis of potentially open-loop unstable systems, which encompasses the classical soft integral quadratic constraint (IQC) theorem, may be recovered by hard IQC theory. The latter is known to be subsumable by the more general soft IQC theory endowed with homotopies that are continuous in the gap topology. In addition, we demonstrate how the aforementioned classical soft IQC theorem, initially introduced for the analysis of a ...

摘要:In feedback control of dynamical systems, the choice of a higher loop gain is typically desirable to achieve a faster closed-loop dynamics, smaller tracking error, and more effective disturbance suppression. Yet, an increased loop gain requires a higher control effort, which can extend beyond the actuation capacity of the feedback system and intermittently cause actuator saturation. To benefit from the advantages of a high feedback gain and simultaneously avoid actuator saturation, this articl...

摘要:In this article, the zonotope-based distributed set-membership state estimation problem is considered for a class of nonlinear multirate complex networks (MRCN) subjected to unknown but bounded (UBB) noises and eavesdropping attacks. Both the process and measurement noises and the system linearization errors are constrained within known zonotopes. To ensure the communication security between the sensor and the estimator, an encryption-decryption mechanism (EDM) is proposed to prevent data from...
