Digital Control Engineering: Analysis and Design Review

Average Reviews:

(More customer reviews)For many digital systems, linearity is assumed. The book then explains how an elegant control systems theory can be applied to design and understand such systems. The maths involves complex analysis, at the level of Marsden's treatment, Basic Complex Analysis. So you learn how to define a transfer function matrix and find its poles and zeros.
Luckily these days, for the grotty numerical stuff, you can use Matlab, and the book has simple sample Matlab code, that shows how easy that package is for engineers. A great improvement over the days when some of us [ie. me] had to resort to a calculator or hand written Fortran code to do the matrix manipulations.
The theory of Finite Impulse Response [FIR] filters is lightly touched upon. Nothing on Infinite Impulse Response [IIR], however.
There are numerous problems for each chapter, some of which can be done by hand, while others involve Matlab.

Digital controllers are part of nearly all modern personal, industrial, and transportation sytems.Every senior or graduate student of electrical, chemical or mechanical engineering should therefore be familiar with the basic theory of digital controllers.This new text covers the fundamental principles and applications of digital control engineering, with emphasis on engineering design. Extensive Use of computational tools:Matlab sections at end of each chapter show how to implement concepts from the chapter.Frees the student from the drudgery of mundane calculations and allows him to consider more subtle aspects of control system analysis and design.An engineering approach to digital controls:emphasis throughout the book is on design of control systems.Mathematics is used to help explain concepts, but throughout the text discussion is tied to design and implementation.For example coverage of analog controls in chapter 5 is not simply a review, but is used to show how analog control systems map to digital control systems. Review of Background Material: contains review material to aid understanding of digital control analysis and design.Examples include discussion of discrete-time systems in time domain and frequency domain (reviewed from linear systems course) and root locus design in s-domain and z-domain (reviewed from feedback control course).Inclusion of Advanced TopicsIn addition to the basic topics required for a one semester senior/graduate class, the text includes some advanced material to make it suitable for an introductory graduate level class or for two quarters at the senior/graduate level.Examples of optional topics are state-space methods, which may receive brief coverage in a one semester course, and nonlinear discrete-time systems.Minimal Mathematics PrerequisitesThe mathematics background required for understanding most of the book is based on what can be reasonably expected from the average electrical, chemical or mechanical engineering senior.This background includes three semesters of calculus, differential equations and basic linear algebra.Some texts on digital control require more mathematical maturity and are therefore beyond the reach of the typical senior.
