Summary Table of Contents Author Biography

This revised and updated edition deals with the modeling of physical systems and features extensive use of bond graphs to illustrate and model these systems. Its coverage encompasses electromechanical transducers, mechanical systems in plane motion, and formulas for computing hydraulic compliances and for modeling acoustic systems.

This is a revision of a book currently in its fourth edition which deals with the modeling of physical systems. With this edition (as with prior editions) one of the key features is the ... MOREextensive use of bond graphs to illustrate and model physical systems. Dynamic systems are taught either using bond graph or not - so the market for Karnopp's book is clearly defined. Bond graphs are a graphical breakdown of a system which illustrates the structure of the system focusing on the flow of information and energy. In this way engineers can better understand the overall system, the various components, and whether they are electrical, chemical, mechanical, etc. The book includes coverage of electromechanical transducers, mechanical systems in plane motion, and formulas for computing hydraulic compliances and for modeling acoustic systems. New chapters and sections are being added that cover the use of physical system models beyond simply predicting system performance - including automatic control, observers, parameter studies for system design, and concept testing. As with the previous editions there will be a solutions manual to accompany this edition.

An expanded new edition of the bestselling system dynamics book using the bond graph approach A major revision of the go-to resource for engineers facing the increasingly complex job of dynamic systems design, System Dynamics, Fifth Edition adds a completely new section on the control of mechatronic systems, while revising and clarifying material on modeling and computer simulation for a wide variety of physical systems. This new edition continues to offer comprehensive, up-to-date coverage of bond graphs, using these important design tools to help readers better understand the various components of dynamic systems. Covering all topics from the ground up, the book provides step-by-step guidance on how to leverage the power of bond graphs to model the flow of information and energy in all types of engineering systems. It begins with simple bond graph models of mechanical, electrical, and hydraulic systems, then goes on to explain in detail how to model more complex systems using computer simulations. Readers will find: New material and practical advice on the design of control systems using mathematical models New chapters on methods that go beyond predicting system behavior, including automatic control, observers, parameter studies for system design, and concept testing Coverage of electromechanical transducers and mechanical systems in plane motion Formulas for computing hydraulic compliances and modeling acoustic systems A discussion of state-of-the-art simulation tools such as MATLAB and bond graph software Complete with numerous figures and examples, System Dynamics, Fifth Edition is a must-have resource for anyone designing systems and components in the automotive, aerospace, and defense industries. It is also an excellent hands-on guide on the latest bond graph methods for readers unfamiliar with physical system modeling.
