Introduction to control systems

by D. K. Anand

Since the second edition of this classic text for students and engineers appeared in 1984, the use of computer-aided design software has become an important adjunct to the study of control system analysis and design. With this in mind the entire text has been recast, enlarged and updated. In addition the scope of the book has been extended so that it is suitable for students of mechanical and electrical engineering, as well as other students of control systems. Many of the classical analytical and graphical techniques have been retained because of their important conceptual role in understanding control system design, although the use of computer techniques in their application is encouraged and emphasized. The concept of a system S has been highlighted in the text, and various mathematical representations of it by the transfer function and State equation are carefully examined in early chapters. In discussing feedback control, the concept of robustness is introduced as a means of stud
