Discrete Feedback Systems 1.

Classical Control


Nyquist Stability Criterion (CT)

The Nyquist stability criterion, as a stability test for LTI systems formulated in the FD, is based on the complex analysis result known as Cauchy’s principle of argument. The importance of Nyquist stability lies in the fact that it can also be used to determine the relative degree of system stability by producing the so-called phase and gain stability margins. These stability margins are needed for FD controller design techniques. The Nyquist method can also be used for studying the stability of linear systems with pure time delay. The Nyquist stability test is obtained by applying the Cauchy principle of argument to the complex function T(s)=11+C(s)G(s)=11+L(s).

The aim of the book is to provide a well-rounded exposure to analysis, control and simulation of discrete-time systems. Theoretical techniques for studying discrete-time linear systems with particular emphasis on the properties and design of sampled data feedback control systems are introduced. This book is intended to be used as a textbook in our MSc and PhD courses. We have tried to balance the broadness and the depth of the material covered in the book. The interested reader is also sent to consult the publications of the references list.
