Cyber-Physical Distributed Systems de Huadong Mo

Cyber-Physical Distributed Systems

Autor Huadong Mo, Giovanni Sansavini, Min Xie
en Limba Engleză Hardback – 23 aug 2021

După parcurgerea acestui volum, cititorul va fi capabil să execute analize complexe de fiabilitate stocastică și să proiecteze strategii de control pentru sisteme distribuite unde interacțiunea dintre hardware și rețeaua digitală este critică. Găsim în această lucrare, semnată de Huadong Mo, Giovanni Sansavini și Min Xie, o abordare riguroasă a modului în care atacurile cibernetice și degradarea rețelei influențează stabilitatea infrastructurilor critice. Observăm o tranziție logică de la conceptele fundamentale de modelare la aplicații avansate în rețelele de energie, oferind instrumente matematice pentru gestionarea incertitudinii. Suntem de părere că forța acestui text rezidă în echilibrul dintre teorie și simulare practică. Structura este riguros etapizată: începe cu provocările sistemelor tradiționale, trece prin fundamentele Cyber-Physical Systems (CPS) și culminează cu tehnici de optimizare a performanței prin algoritmi precum PSO (Particle Swarm Optimization) și control automat al generării (AGC). Un element distinctiv este includerea simulatorului TrueTime, care permite verificarea modelelor într-un mediu controlat înainte de implementare. Complementar volumului Cyber Physical Systems Approach to Smart Electric Power Grid, care se concentrează strict pe rețelele inteligente, Cyber-Physical Distributed Systems acoperă zona critică a proceselor de îmbătrânire a componentelor și mentenanța preventivă în timp real, aspecte deseori omise în literatura de specialitate. De asemenea, spre deosebire de Distributed Linear Programming Models in a Smart Grid, care utilizează predominant programarea liniară, autorii de față propun un cadru mai larg, de tip „sistem-de-sisteme”, esențial pentru înțelegerea degradării rețelelor complexe.

Descriere

CYBER-PHYSICAL DISTRIBUTED SYSTEMS

Gather detailed knowledge and insights into cyber-physical systems behaviors from a cutting-edge reference written by leading voices in the field

In Cyber-Physical Distributed Systems: Modeling, Reliability Analysis and Applications, distinguished researchers and authors Drs. Huadong Mo, Giovanni Sansavini, and Min Xie deliver a detailed exploration of the modeling and reliability analysis of cyber physical systems through applications in infrastructure and energy and power systems. The book focuses on the integrated modeling of systems that bring together physical and cyber elements and analyzing their stochastic behaviors and reliability with a view to controlling and managing them.

The book offers a comprehensive treatment on the aging process and corresponding online maintenance, network degradation, and cyber-attacks occurring in cyber-physical systems. The authors include many illustrative examples and case studies based on real-world systems and offer readers a rich set of references for further research and study.

Cyber-Physical Distributed Systems covers recent advances in combinatorial models and algorithms for cyber-physical systems modeling and analysis. The book also includes:

  • A general introduction to traditional physical/cyber systems, and the challenges, research trends, and opportunities for real cyber-physical systems applications that general readers will find interesting and useful
  • Discussions of general modeling, assessment, verification, and optimization of industrial cyber-physical systems
  • Explorations of stability analysis and enhancement of cyber-physical systems, including the integration of physical systems and open communication networks
  • A detailed treatment of a system-of-systems framework for the reliability analysis and optimal maintenance of distributed systems with aging components

Perfect for undergraduate and graduate students in computer science, electrical engineering, cyber security, industrial and system engineering departments, Cyber-Physical Distributed Systems will also earn a place on the bookshelves of students taking courses related to reliability, risk and control engineering from a system perspective. Reliability, safety and industrial control professionals will also benefit greatly from this book.
