Modeling and Density Estimation of an Urban Freeway Network Based on Dynamic Graph Hybrid Automata [PDF]

open access: yesSensors, 2017
In this paper, in order to describe complex network systems, we firstly propose a general modeling framework by combining a dynamic graph with hybrid automata and thus name it Dynamic Graph Hybrid Automata (DGHA).

Cyberphysical System Modeled with Complex Networks and Hybrid Automata to Diagnose Multiple and Concurrent Faults in Manufacturing Systems

open access: yesApplied Sciences, 2023
Cyber–physical systems use digital twins to provide advanced monitoring and control functions, including self-diagnosis. The digital twin is often conceptualized as a 3D model, but mathematical models implemented in numerical simulations are required to ...

Improving HyLTL model checking of hybrid systems [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2013
The problem of model-checking hybrid systems is a long-time challenge in the scientific community. Most of the existing approaches and tools are either limited on the properties that they can verify, or restricted to simplified classes of systems.

Hybrid Automata as Coalgebras [PDF]

open access: yes, 2016
Able to simultaneously encode discrete transitions and continuous behaviour, hybrid automata are the de facto framework for the formal specification and analysis of hybrid systems. The current paper revisits hybrid automata from a coalgebraic point of view.

Optimization Control of Front-End Speed Regulation (FESR) Wind Turbine Based on Improved NSGA-II

open access: yesIEEE Access, 2019
Aiming at the power optimization control problem of front-end speed regulation (FESR) wind turbine, when the wind speed above rated wind speed, an optimal control strategy of variable pitch and variable torque based on improved NSGA-II algorithm is ...
