Discrete Feedback Systems 1.

Classical Control

Sampled systems

Finding the discrete equivalent of a continuous system is desired when a discrete equivalent of a continuous plant is needed to simulate a sampled-data system. Recall that in a sampled-data system the controller is discrete while the plant is continuous. To simulate the entire system as a discrete-time system one needs to find the discrete equivalent of the plant preceded by a hold circuit, and followed by a sampler. Another choice is to design a digital controller for a continuous-time plant one may directly design a digital controller. Alternatively, one may take advantage of the knowledge available on continuous-control design by taking the following two steps: first design a continuous-time controller for the plant. Note that the designer should take into account the T/2 seconds delay introduced by sampling and hold device. Then, find the discrete equivalent of the CT design, for implementation by a digital computer. This design method is called emulation.

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.
