Introduction to System Dynamics

Rowell and Wormley use a linear graph approach. This contrasts with the bond graph approach or no graph approach. This is the first modern linear graph System Dynamics that has been published in 30 years. Chapters are organized so that introductory material is presented first, with more advanced topics coming later. Contains exceptionally clear presentation of Frequency response. Features detailed development of the construction of lumped-parameter system models from sets of primitive elements; and modeling techniques are presented using an energy based state-space formulation method that provides linkages to classical system representations.

Emphasizing applications to engineering systems, the authors (mechanical engineering, MIT) develop in detail the basis for constructing a lumped-parameter system model from a set of primitive elements, and understanding the transient and frequency response performance of the model. A sampling of topics: energy and power flow in state-determined systems, one-port primitive elements, energy- transducing system elements, operational methods for linear systems, linear state equations, system response by numerical simulation, impedence-based modeling methods, and partial fraction expansion of rational functions.
