: A simplified approach to the Nyquist criterion specifically tailored for the digital domain.
Furthermore, the book is lauded for its treatment of system stability. The mapping of the $s$-plane to the $z$-plane is a concept that often trips up students, yet Kuo’s graphical and analytical explanations demystify the stability criteria. The inclusion of Jury’s stability test and the bilinear transformation method provides engineers with the practical algorithms needed to verify if a digital controller will remain stable under real-world conditions. digital control systems benjamin kuo pdf
