Written for the advanced undergraduate, this book has two unique features. The first is the overall understanding of the fundamentals of modeling and simulation as well as the understanding of software and hardware systems. The second is the scope and number of the carefully selected applications. The book contains a large number of examples, figures, problems, and references. Topics include nonlinear systems analysis and modeling, continuous-time and discrete-time linear systems, electric power systems modeling, and simulation. Several examples of the use of MATLAB for system simulation and analysis are provided.
