System Dynamics includes the strongest treatment of computational software and system simulation of any available text, with its early introduction of MATLAB® and Simulink®. The text's extensive coverage also includes discussion of the root locus and frequency response plots, among other methods for assessing system behavior in the time and frequency domains as well as topics such as function discovery, parameter estimation, and system identification techniques, motor performance evaluation, and system dynamics in everyday life.
