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 development history of automatic control theory. Chapter 2 illustrates mathematical modeling methods for control systems using practical examples such as mechanical and electrical systems. Chapter 3 discusses performance indicators of time-domain responses in second-order systems and the Routh criterion for stability analysis. Chapter 4 introduces the principles of root locus, its plotting methods, and system analysis based on root locus. Chapter 5 presents frequency-domain methods for control system analysis, covering the construction of Nyquist plots and Bode plots (logarithmic frequency response) and their applications in system performance and stability analysis. Chapter 6 covers 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 common nonlinear system analysis methods such as the describing function method and phase-plane method. Chapter 8 introduces the fundamental theories, mathematical models, stability, steady-state error, and dynamic performance analysis methods for linear discrete systems. This book can serve as a textbook for undergraduate electrical and information engineering majors studying "Automatic Control Principles" and is also a valuable reference for related engineering professionals.
