Generalized Detectability for Discrete Event Systems. [PDF]
Syst Control Lett, 2011 In our previous work, we investigated detectability of discrete event systems, which is defined as the ability to determine the current and subsequent states of a system based on observation. For different applications, we defined four types of detectabilities: (weak) detectability, strong detectability, (weak) periodic detectability, and strong ...

Detectability of Discrete Event Systems with Dynamic Event Observation. [PDF]
Syst Control Lett, 2010 Our previous work considers detectability of discrete event systems which is to determine the current state and subsequent states of a system based on event observation. We assume that event observation is static, that is, if an event is observable, then all its occurrences are observable.

Detectability of Timed Discrete Event Systems
IEEE Access, 2023 This paper introduces T-detectability, which extends detectability to timed discrete event systems within the context of communication networks. We propose network T-detectability to address the challenges posed by observation delays and losses in ...

Overview of Opacity in Discrete Event Systems
IEEE Access, 2020 In recent years, opacity has received increasing attention in terms of analyzing security and privacy problems. Opacity is a confidentiality property that characterizes a system's ability to hide its secret information from any external intruders.

Robust predictability in discrete event systems under sensor attacks
Frontiers in Physics, 2023 The problem of robust predictability against sensor attacks is investigated. The objective of a diagnoser is to predict the occurrence of a critical event of a discrete event system (DES) under partial observation.

Joint State Estimation Under Attack of Discrete Event Systems
IEEE Access, 2021 The problem of state estimation in the setting of partially-observed discrete event systems subject to cyber attacks is considered. An operator observes a plant through a natural projection that hides the occurrence of certain events.

Hidden Markov Models as a Process Monitor in Robotic Assembly [PDF]
Modeling, Identification and Control, 1999 A process monitor for robotic assembly based on hidden Markov models (HMMs) is presented. The HMM process monitor is based on the dynamic force/torque signals arising from interaction between the workpiece and the environment.

Detectability in Discrete Event Systems Using Unbounded Petri Nets
Mathematics, 2023 This paper investigated the verification of detectability for discrete event systems based on a class of partially observed unbounded Petri nets. In an unbounded net system, all transitions and partial places are assumed to be unobservable.

Event-Triggered Disturbance Rejection Control of Discrete Systems
IEEE Access, 2020 This paper considers event-triggered disturbance rejection control for discrete time linear systems. A novel event-based disturbance rejection controller is designed, and sufficient conditions are given to guarantee that the closed-loop system is ...

Event Scheduling in Simulation of Discrete Event Systems with Application on Queuing Systems. [PDF]
المجلة العراقية للعلوم الاحصائية, 2010 Queuing theory and other of discrete and continuous event systems have theory aesthetic but the more assumptions which indepent these theories are not accurate as compared with real situation, also the queue problem is one of the most scientific problems
