Automatic control plays an important role in the advance of engineering and science. It is of extreme importance in most of the engineering fields; such as the aerospace engineering, chemical engineering, robotic systems, automotive and mobile equipment engineering as well as manufacturing and industrial processes. Automatic control provides the means of understanding the problems of stability and precision of dynamic systems. Actually most engineers must have good understanding of this field.

The majority of textbooks on automatic control are most appropriated for electrical engineers. The main problem in designing and analyzing a control loop for non-electrical systems normally arises when deducing adequate mathematical model for the system. Generally, the components cannot readily be represented by simple discrete ideal elements. The classical approach based on the transfer function and associated techniques of analysis is more easily comprehended and related to practice by the beginners than is the modern control theory. Therefore this text is prepared for the mechanical engineering students. It deals with the basics of linear control theory. The text includes simple examples enabling applicants to understand the problems of dynamic systems accuracy and stability. The text includes examples and exercises that facilitate the comprehension of the control theory, especially for the mechanical engineering students. The text is arranged in ten chapters dealing with the following topics:
