Introduction to Engineering Systems [PDF ebook] 
Pergamon Unified Engineering Series

An Introduction to Engineering Systems discusses important aspects of systems engineering. It provides a background of analytical methods appropriate to hand-solution and computer solutions and shows the correlation that exists in alternate formulation. The book begins with an introduction to models and modeling of system elements. It then discusses the equilibrium formulations, signal flow graphs, and geometrical constraints of interconnected systems. After exploring aspects of system response and behavior in the time domain, the analyzes system response in the frequency domain. It also describes Z-transform methods and their application to discrete and continuous time systems. Finally, the book presents several approaches for testing the stability of linear systems. The text will provide students essential understanding of important methods of modern systems analysis.
