Digital Control Engineering: Analysis and Design

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.
