Negative Positive
Title: hard book
Review: The book is not readable and you have to be an expert in the geometric nonlinearcontrol area to follow the book. Before reading the book, you have to masterthe related concepts of differential geometry.The differential geometry summary given in the book is not easy to understand and digest.The book does not have enough examples also.Finally, it just involves geometric control techniques and not others.Hence, its title should be geometric nonlinear control.This book is not a book to learn different nonlinear control techniques in the nonlinear control area.
Is the review positive or negative?
