Varmah K. Modern Control Theory 2018

Textbook in PDF format

All the theories and the methods employed in the analysis and design of linear control systems are not applicable to nonlinear systems.
State space techniques are applicable, equally well, to both linear and nonlinear systems. This book introduces students to the modern control theory based on state variables and state space. It gives a basic approach to the design and analysis of continuous time control systems using state space representations.
The main objective of writing this second level book in control systems is the feeling that very few text books are available that cater to the needs of students: a book that presents the theories and explanations in a simple and lucid manner that help students to learn and imbibe the concepts without much difficulty.
Each chapter ends with a summary of subject matter discussed. Many practice problems and review questions are included that.
enable the students to test their understanding of the subject.
