Digital Control System analysis and design

This book is intended to be used primarily as a text for a first course in discrete-time control
systems at either the senior undergraduate or first-year graduate level. Furthermore, the text is
suitable for self-study by the practicing control engineer.Chapter 1 presents a brief introduction and an outline of the text. Chapters 2–11 cover
the analysis and design of discrete-time linear control systems. Some previous knowledge
of continuous-time control systems is helpful in understanding this material. The mathematics
involved in the analysis and design of discrete-time control systems is the z-transform and
vector-matrix difference equations; these topics are presented in Chapter 2. Chapter 3 is devoted
to the very important topic of sampling signals and the mathematical model of the sampler and
data hold. This model is basic to the remainder of the text. The implications and the limitations
of this model are stressed.
The next four chapters, 4–7, are devoted to the application of the mathematics of Chapter 2
to the analysis of discrete-time systems, emphasis on digital control systems. Classical design
techniques are covered in Chapter 8, with the frequency-response Bode technique emphasized.
Modern design techniques are presented in Chapters 9–11. Chapter 12 summarizes some case
studies in discrete-time control system design. Throughout these chapters, practical computer aided
analysis and design using MATLAB are stressed.
