Preface
Dear Students,
It gives us great pleasure to present to you this book on
“Mechatronics” written specially for you.
This text book has been written strictly as per the revised Syllabus prescribed by Pune University for Fourth Year Mechanical Engineering students.
An attempt have been made by us to write this book in a simple and lucid language with neat and self-explanatory diagrams which could be easily understood by an average student. We have also kept in mind the examination requirement of the students.
The unique features of this book are :
(1) Self explanatory diagrams and pointwise explanation of each topics.
(2) A special introductory topic on Laplace Transform has been provided for easy understanding of Control System portion for students.
(3) Solutions of University Paper on Mechatronics for Mech Sandwich Branch has been provided.
(4) Complete symbols of JIC/ISO has been provided for familiarization with PLC ladder diagrams.
Every care has been taken to make the book error free. However if you find any mistake please do let us know, because that will help us for further improvement of the book.
