Control Systems presents a simplified approach to control systems theory and analysis, by rendering a full and explicit account of basic terms and concepts; theories and analyses; solved examples and demonstrations. The main topics of interest in control systems theories are covered in the book, including: linear systems and differential equation modeling; Mathematical modeling of physical systems; Laplace transforms; block diagram algebra; feedback analysis; time response; stability of control systems; frequency response; Nyquist stability analysis; Bode analysis and root locus.
