EBOOK - Analysis and Design of control Systems using Matlab (Rao V. Dukkipati)


Control Systems Engineering is an exciting and challenging field and is a multidisciplinary subject. This book is designed and organized around the concepts of control systems engineering using MATLAB, as they have been developed in the frequency and time domain for an introductory undergraduate or graduate course in control systems for engineering students of all disciplines.
Chapter 1 presents a brief introduction to control systems.
The fundamental strategy of controlling physical variables in systems is presented. Some of the terms commonly used to describe the operation, analysis, and design of control systems are described.
An introduction to MATLAB basics is presented in Chapter 2. Chapter 2 also presents MATLAB commands.

MATLAB is considered as the software of choice. MATLAB can be used interactively and has an inventory of routines, called as functions, which minimize the task of programming even more. Further information on MATLAB can be obtained from: The MathWorks, Inc., 3 Apple Hill Drive, Natick, MA 01760. In the computational aspects, MATLAB has emerged as a very powerful tool for numerical computations involved in control systems engineering. The idea of computer-aided design and analysis using MATLAB with the Symbolic Math Tool box, and the Control System Tool box has been incorporated.
Chapter 3 consists of many solved problems that demonstrate the application of MATLAB to the analysis and design of control systems. Presentations are limited to linear, time-invariant continuous time systems.
Chapters 2 and 3 include a great number of worked examples and unsolved exercise
problems to guide the student to understand the basic principles and concepts in control systems engineering.
I sincerely hope that the final outcome of this book helps the students in developing an appreciation for the topic of analysis and design of control systems.
An extensive bibliography to guide the student to further sources of information on control systems engineering is provided at the end of the book. All the end-of chapter problems are fully solved in the Solution Manual available only to Instructors.
