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.‎ New chapters and sections treat the use of physical system models beyond simply predicting system performance‎,‎ including automatic control‎,‎ observers‎,‎ parameter studies for system design‎,‎ and concept testing‎.‎ In addition‎,‎ the text utilizes state‎-of‎-the‎-art software tools ‎(‎MATLAB and bondgraph software‎)‎ for examples and art generation‎.‎
