摘要:Scenario optimization is a broad scheme for data-driven decision-making in which experimental observations act as constraints on the feasible domain for the optimization variables. The probability with which the solution is not feasible for a new, out-of-sample, observation is called the risk. Recent studies have unveiled the profound link that exists between the risk and a properly defined notion of complexity of the scenario solution. In the present article, we leverage these results to intr...

摘要:Structural identifiability is a property of a differential model with parameters that allows for the parameters to be determined from the model equations in the absence of noise. The method of input-output (IO) equations is one method for verifying structural identifiability. This method stands out in its importance because the additional insights it provides can be used to analyze and improve models. However, its complete theoretical grounds and applicability are still to be established. A su...

摘要:This article proposes the event-triggered state-feedback and dynamic output-feedback control of positive Markovian jump systems with intermittent actuator and sensor faults. An independent Markovian process is used to establish the mathematical model of the intermittent fault. An event-triggering condition based on 1-norm is proposed to implement the event-triggered scheme. An event-triggered state-feedback controller is designed using stochastic copositive Lyapunov functions. By virtue of a m...

摘要:The importance of estimating the region of attraction (ROA) on complex networks has drawn attention very recently. However, challenging problems arise when applying the existing theory to networks with delay. In this article, we estimate the ROA on controlled complex networks with time-varying delay. A delay-independent ROA estimation method is derived at first. This method can deal with general delay and is convenient to use due to its independence of the delay. Accordingly, it may cause cons...

摘要:This technical note investigates the problem of extended dissipative finite-time control for Markov jump systems (MJSs) with cyber-attacks and actuator failures. A probabilistic event-triggered mechanism (PETM) is proposed to relieve the communication burden by exploiting both the pattern variation of triggering thresholds and the time-varying characteristic of transmission delays. To characterize the actual control inputs, a stochastic actuator failure model (SAFM) is established using a rand...

摘要:This article tackles the problem of stability analysis for uncertain sampled-data systems consisting of the feedback interconnection between a nominal linear time-invariant (LTI) sampled-data system and a structured linear time-varying (LTV) model uncertainty. When the L-infinity norm and its induced norm are taken into account to characterize such uncertain systems, it has been shown that the necessary and sufficient condition for robust stability of such uncertain sampled-data systems is des...

摘要:This paper investigates the problem of securing exponentially fast consensus (exponential consensus for short) for identical agents with finite dimensional linear system dynamics over dynamic network topology. Our aim is to find the weakest possible conditions that guarantee exponential consensus using a Lyapunov function consisting of a sum of terms of the same functional form. We first investigate necessary conditions, starting by examining the system parameters. It is found that controllabi...

摘要:The solvability of certainty equivalence control problems for discrete-time multiagent systems over uniformly jointly connected switching networks relies on the stability/attractivity analysis for a class of perturbed switched systems with respect to a set of switching signals. To tackle this issue, in this article, a novel systematic and unified framework is established consisting of three key stability/attractivity results. First, the uniform global exponential stability for two dual cases o...

摘要:In this note, we study the prescribed-time (PT) synchronization of the multiweighted and directed complex networks (MWDCNs). Unlike finite-time and fixed-time synchronization, the time for synchronization can be prescribed as needed, which is independent of initial values and parameters, such as coupling matrix. At first, we define a class of regulatory functions whose improper integrals diverge, and it is proved to play a key role in PT stability for dynamical systems. Many special functions ...

摘要:This article studies the robustness of observability of a linear time-invariant system under sensor failures from a computational perspective. Our aim is to determine the minimum number of sensors that, if removed, would render the system unobservable, and to determine the minimum number of state variables that need to be shielded from direct measurement by existing sensors to destroy system observability, both in numerical and structural (or structured) system models. The first problem is clo...
