Features: This book closely integrates engineering practice, systematically introducing the composition principles, analysis methods, and design methods of typical automatic control systems, along with practical system circuits and design examples. The content includes DC speed control systems, AC speed control systems, and position servo systems. The DC speed control system, after introducing pulse phase control and pulse width modulation speed control systems, takes the pulse phase control system as an example to explain various closed-loop control methods and the analysis and design methods of closed-loop control systems. The AC speed control system focuses on frequency conversion speed control, with an emphasis on the control concepts of slip frequency control, vector transformation control, and direct torque control. The position servo system primarily covers the analysis, design, debugging, and fault diagnosis of high-precision position servo systems. It also specially introduces nonlinear compensation, the effects of dry friction, mechanical resonance, and rotation gaps on servo systems and their compensation methods, as well as relatively newer topics such as the robustness, reliability, and electromagnetic compatibility of servo systems. The book also takes servo systems as examples to explain the digital control principles, analysis methods, and design methods of automatic control systems. The selection of material considers both fundamental theories and engineering practicality. The narrative is designed to be both in-depth and accessible, with typical circuits and diagrams. This book can serve as a textbook or reference for undergraduate and graduate students in automation, electromechanical, and related fields at universities. It is also suitable for researchers and engineering design personnel. National Defense Industry and Science Technology Commission "Fifteenth Five-Year Plan" Textbook · Control Science and Engineering.
