"Computer-Controlled Systems: Theory and Design" Third Edition by Karl J. Åström and Björn Wittenmark provides a comprehensive overview of computer-controlled systems, covering both theoretical foundations and practical design methods. The book is structured into 13 chapters, each focusing on different aspects of computer-controlled systems. Chapter 1 introduces computer control, including computer technology and control theory. Chapter 2 discusses discrete-time systems, including sampling, state-space models, and the z-transform. Chapter 3 focuses on the analysis of discrete-time systems, including stability, sensitivity, and feedback loops. Chapter 4 presents pole-placement design using a state-space approach, while Chapter 5 explores a polynomial approach to pole-placement design. Chapter 6 provides an overview of design principles, including operational aspects and design methods. Chapter 7 covers process-oriented models, including sampling, reconstruction, and frequency response. Chapter 8 discusses approximating continuous-time controllers, including transfer functions and state models. Chapter 9 addresses the implementation of digital controllers, including programming and numerical methods. Chapter 10 explores disturbance models, including stochastic processes and sampling. Chapter 11 and 12 present optimal design methods, including linear quadratic control and polynomial approaches. Chapter 13 covers system identification, including model building and least squares methods. Appendices provide examples, matrix functions, and references. The book is a valuable resource for engineers and researchers in the field of computer-controlled systems, offering both theoretical insights and practical design techniques."Computer-Controlled Systems: Theory and Design" Third Edition by Karl J.
