Digital Control System Analysis & Design, 4th Edition, is a Pearson textbook that emphasizes practical aspects of designing and implementing digital control systems.

The volume addresses core topics in discrete-time controls, ranging from sampling and reconstruction to system time response and closed-loop behavior. It covers foundational tools such as the z-transform alongside methods for stability analysis and digital controller design.

Designed for a one-semester or two-quarter senior-level course in digital or discrete-time controls, the text also serves as a reference for practicing engineers. Simple physical systems introduced early in the book are reused in later chapters to illuminate more advanced material.
