Feedback Systems

This book was the first and remains the only book to give a comprehensive treatment of the behavior of linear or nonlinear systems when they are connected in a closed-loop fashion, with the output of one system forming the input of the other. The study of the stability of such systems requires one to draw upon several branches of mathematics but most notably functional analysis.

Feedback Systems includes the most basic concepts of matrices and norms, the important fundamental theorems in input-output stability, and the requisite background material in advanced topics such as the small gain theorem and the passivity theorem.

Feedback Systems covers:

• The most basic concepts of matrices nd norms
• The important fundamental theorems in input-output stability.
• The requisite background material in advanced topics such as the small gain theorem and passivity theorem.
