From the reviews:

„This book is focused mainly on the analysis of so-called nonlinear flat systems. … The book is published in the mathematical engineering series, and as a consequence the differential geometry content is presented in a very accessible applied mathematics way.“ (Guy Jumarie, Zentralblatt MATH, Vol. 1167, 2009)

“This book provides an introduction to the theory of deterministic, continuous-time, finite-dimensional, nonlinear control systems from the particular ‘differential-algebraic’ point of view, with the notion of ‘flatness’ as the fundamental underlying principle. … this book is the first extensive treatment of the notion of flatness in monograph form. As such, it is certainly a useful addition to the control-theory literature. A particular strength of the book is its detailed treatment of many examples … .” (Kevin A.
