About this book

The book deals with continuous piecewise linear differential systems in the plane with three pieces separated by a pair of parallel straight lines. Moreover, these differential systems are symmetric with respect to the origin of coordinates. This class of systems driven by concrete applications is of interest in engineering, in particular in control theory and the design of electric circuits. By studying these particular differential systems we will introduce the basic tools of the qualitative theory of ordinary differential equations, which allow us to describe the global dynamics of these systems including the infinity. The behavior of their solutions, their parametric stability or instability and their bifurcations are described. The book is very appropriate for a first course in the qualitative theory of differential equations or dynamical systems, mainly for engineers, mathematicians, and physicists.

Reviews

From the book reviews:

“This book is devoted to the study of piecewise linear differential systems (PWLSs), from the point of view of the qualitative theory of differential equations. … this book could serve well both as a textbook for a course in piecewise linear differential equations and as a reference in which important tools of current research are thoroughly explained and their use is illustrated.” (Claudio Pessoa, Mathematical Reviews, November, 2014)

“The monograph presents a detailed study of an important family of continuous piecewise linear differential systems. … The book is of great interest for researches working on planar piecewise linear differential systems. It can also serve as a reference book for those interested in the global phase portraits and the bifurcation sets of fundamental systems. The book is also highly suitable for students and engineers wishing to learn the theory of planar piecewise linear systems … .” (Valery Romanovski, zbMATH, Vol. 1286 (2), 2014)
