Features: This book systematically introduces the fundamental theories and applications of automatic control principles. Chapter 1 provides an in-depth yet accessible explanation of the basic concepts, classifications, and historical development of automatic control theory. Chapter 2 introduces mathematical modeling methods for control systems using practical examples such as mechanical and electrical systems. Chapter 3 discusses performance indicators of the time-domain response in second-order systems and the Routh-Hurwitz criterion for stability analysis. Chapter 4 covers the principles of root locus, its plotting methods, and system analysis based on root locus. Chapter 5 introduces frequency-domain methods for control system analysis, discussing the drawing of Nyquist plots and Bode plots based on logarithmic coordinates and their applications in system performance and stability analysis. Chapter 6 presents control system compensation and design methods for single-output linear time-invariant systems based on root locus and frequency-domain methods. Chapter 7 primarily discusses commonly used nonlinear system analysis methods such as the describing function method and phase plane method. Chapter 8 covers the fundamental theories, mathematical models, stability, steady-state error, and dynamic performance analysis methods of linear discrete systems. This book can be used as a textbook for undergraduate courses on "Automatic Control Principles" in electrical and information engineering disciplines, as well as a reference for relevant engineering professionals.
