Digital Control Systems

This book provides a comprehensive introduction to sampled-data control systems, focusing on their theoretical foundations, mathematical modeling, and practical implementation. It begins with the structure and components of digital control systems, including ADCs, DACs, and digital controllers. Key concepts such as signal sampling, reconstruction, and the use of Zero-Order Hold circuits are discussed in depth. The book explores the Z-transform and its applications in analyzing discrete-time systems, followed by system modeling, stability analysis using criteria like Schur-Cohn and Jury, and system response evaluation. Further chapters cover controller design, static accuracy, digital PID synthesis, and advanced RST control techniques. Through a balanced mix of theory, mathematical tools, and illustrative diagrams, the book aims to equip students, engineers, and practitioners with essential knowledge for designing and analyzing robust digital control systems in real-world applications.
