摘要：Studies carried out in real plants have shown thatrepeated and/or intermittent fault events occur frequently duringthe operation of a system. Regarding the occurrence of repeatedfault events, the problem becomes that of determining the numberof occurrences of the fault event, namely, for a given kappa is an element of Z & lowast;+,and based on the observation of events, be sure that the faultevent has occurred at least kappa times (kappa-diagnosability). In thisarticle, the problem of repeated...

摘要：This article considers gain-scheduling of quadratic supply rate (QSR)-dissipative subsystems using scheduling matrices. The corresponding QSR-dissipative properties of the overall matrix-gain-scheduled system, which depends on the QSR properties of the subsystems scheduled, are explicitly derived. The use of scheduling matrices is a generalization of the scalar scheduling signals used in the literature, and allows for greater design freedom when scheduling systems, such as in the case of gain-...

摘要：In this technical note, we investigate the stability of discrete-time 2-D linear inhomogeneous systems. Specifically, we establish sufficient conditions that guarantee both asymptotic and exponential stability. Compared to existing results, the conditions presented here relax the requirement for the negative definiteness of differences in (piecewise) Lyapunov functions, allowing these functions to grow over certain periods. Numerical examples are provided to illustrate the theoretical findings.

摘要：The aim of this article is to investigate how opinions propagate in presence of stubborn behavior (i.e., agents that tend to defend their stance) and of signed (i.e., antagonistic) interactions among the agents. The stability properties of the resulting system, denoted signed Friedkin-Johnsen (SFJ) model, are studied in detail, and also the convergence to consensus for a concatenation of such SFJ models. A noteworthy feature of the SFJ model is that the opinion dynamics need not be confined to...

摘要：In this article, the consensus problem of multiple Euler-Lagrange (EL) systems with time-varying asymmetric full-state constraints under a directed graph is investigated in a fully distributed way, where the global information dependence is removed. First, to prevent the violation of the full-state constraints of each EL system, a nonlinear state-dependent transformation is adopted for both the leader and followers, where the constraints will not be violated as long as the transformed states r...

摘要：This note focuses on the issue of whether or not the state of a plant can be estimated when the inputs of communication channel involve noise and disturbance simultaneously. It turns out to calculate the maximum capacity of stationary memoryless M-MQAC under nonstochastic information theory. It is shown that the maximum information rate over such a channel is determined by a convex hull spanned by the zero-error capacities, which are specified on the underlying sample spaces. Moreover, the sta...

摘要：This article introduces a class of model-free feedback methods for solving generic constrained optimization problems where the mathematical forms of the cost and constraint functions are not available. The proposed methods, termed projected zeroth-order (P-ZO) dynamics, incorporate projection maps into a class of continuous-time zeroth-order dynamics that use direct measurements of the cost function and periodic dithering for the purpose of gradient learning. In particular, the proposed P-ZO a...

摘要：In this article, we study control synthesis problems for multiagent systems (MASs) that must comply with spatio-temporal logic requirements. We define a logic called team spatio-temporal reach and escape logic (t-STREL) and a robustness metric for it that is continuous everywhere and differentiable almost everywhere. These properties facilitate the use of gradient-based optimization and learning-based control techniques, offering greater efficiency compared to traditional gradient-free methods...

摘要：In this article, we deal with stochastic optimization problems where the data distributions change in response to the decision variables. Traditionally, the study of optimization problems with decision-dependent distributions has assumed either the absence of constraints or fixed constraints. This work considers a more general setting where the constraints can also dynamically adjust in response to changes in the decision variables. Specifically, we consider linear constraints and analyze the ...

摘要：Attack design is indispensable for analyzing potential risks of networked control systems (NCSs). However, the remote control center is usually well protected and its knowledge is difficult to be disclosed, which becomes a major obstacle in developing stealthy false data injection (FDI) attack scheme because only partial system knowledge (i.e., the system matrices of the physical plant) could be used. To meet this challenge, a novel stealthy FDI attack scheme against the sensor measurement is ...
