"Automatic Control Engineering" by Francis H. Raven, 5th edition, covers the design, analysis, and optimization of control systems. It begins with how control systems can be represented by block diagrams, including representing components and connecting diagrams. The book emphasizes nonlinear components and obtaining information from steady-state behavior. It also covers solving linear differential equations using Laplace transforms, transient behavior, root-locus method, analog computer simulation, state-space methods, digital control systems, frequency-response methods, and system compensation. Automatic control is used to maintain process variables at desired operating values. It is essential for automation and precision control in manufacturing processes.
