Provides an introduction to the design of industrial control systems using the polynomial systems design approach. The author demonstrates the value of a frequency domain approach to robust design using H-inf or LQG design and provides the results of polynomial systems theory for the design of industrial controllers and filters. Applications chapters provide a range of realistic industrial control design studies, and the book is accompanied by a disc that provides a MATLAB toolbox and PROGRAM CC macros that can be used to evaluate the case study examples.
