摘要：In this article, we consider the problem of observer design for heat diffusion-reaction partial differential equations (PDEs) that are monitored through delayed boundary sensor measurements. The novelty with respect to the existing observers lies in the fact that the PDE is subject to parameter uncertainties coming not only in the domain but also in the sensor. We develop an adaptive observer that provides online accurate estimates of both the state and parameter estimates. The observer design...

摘要：This article reports necessary stability conditions for a parabolic partial differential equation (PDE) interconnected through the boundaries to an ordinary differential equation (ODE). We intend to propose numerical certificates for the instability of such interconnections. From one side, using spectral methods, we derive a necessary analytical condition based on root locus analysis, which can be tested in the parameters space. On the other side, using Lyapunov direct and converse approaches,...

摘要：We consider open games where players arrive according to a Poisson process with rate lambda and stay in the game for an exponential random duration with rate mu. The game evolves in continuous time, where each player n sets an exponential random clock and updates his/her action an is an element of{0,...,K}when it expires. The players take independent actions according to local decision rules that, uninterrupted, are designed to converge to an equilibrium. When lambda is small, the game spends ...

摘要：This article provides an linear matrix inequality (LMI)-based procedure for reaching time estimation of the multivariable super-twisting algorithm dealing with convex bounded parameter uncertainty and exogenous disturbances with norm-bounded time-derivative. For a class of Lyapunov functions, we are able to determine the optimal reaching time estimation that emerges from the solution of a surprisingly simple mathematical programming problem. As far as the reaching time estimation and validatio...

摘要：Advanced persistent threats (APTs) are stealthy attacks by intelligent adversaries. This article studies the detection of APTs that infiltrate cyber systems and compromise specifically targeted data and/or infrastructures. Dynamic information flow tracking is an information trace-based detection mechanism against APTs that tags suspicious information flows in the system and performs security analysis for unauthorized use of tagged data. In this article, we develop an analytical model for resou...

摘要：This article focuses on the problem of enforcing current-state opacity of a discrete event system via editing functions. In more detail, the observation exposed to an intruder is modified, either erasing or inserting some observations, so as to guarantee that the intruder is not able to discover the predefined secret. The notion of concealability, which formalizes the possibility of maintaining the secret hidden, is introduced starting from defining some illegal states on a particular structur...

摘要：This article considers the stabilization issue of highly nonlinear delayed stochastic networks (HNDSNs) based on periodic self-triggered intermittent control under sampled-data (PICS) for the first time. Therein, the linear growth condition is taken off, and some PICS-based stabilization conditions in previous works are weakened. It is worth pointing out that the existing results are suitable for highly nonlinear networks neither based on PICS nor considering the time-varying delay. Given this...

摘要：The purpose of this article is to develop a general framework of mean-square robust control in the presence of stochastic multiplicative uncertainties. We consider block diagonally structured stochastic uncertainties of a variety of structures including diagonal scalar, element-by-element, repeated scalar and full-block stochastic processes with prescribed variance bounds, which may arise from multiple sources and can be used to model various communication losses. In an important distinction f...

摘要：For a retarded nonlinear system with a Lipschitz nonlinearity on bounded sets outside the origin, this article proposes necessary conditions for application of the Lyapunov-Razumikhin method. The presented conditions are illustrated on the classes of linear and nonlinear homogeneous systems.

摘要：Decision-making mechanisms are typically either of imitation, that is, to copy the action of successful fellows, coordination, that is, to take an action if enough fellows have done so, or anticoordination, that is to take an action if few fellows have done so. The resulting decision-making dynamics of a mixture of individuals following these three mechanisms may either eventually reach an equilibrium state where no one tends to switch strategies or enter a nonsingleton positively invariant se...
