Linear Control Systems: For PTU is a comprehensive text designed to cover the complete syllabus of the subject offered at Punjab Technical University (PTU), at the undergraduate level. The book begins with various modeling techniques of control system viz Transfer function approach, block diagram representation and signal flow graphs. The characteristics and performance of control systems has been dealt with in details. Concept of stability and various techniques for determining stability through Routh-Hurwitz criteria, Root locus Techniques, Bode plot and Nyquist stability criteria have been discussed. Design and compensation of control components have been explained.
