Automatic Control for Mechanical Engineers- for free


It is essential for engineers to understand the nature of the dynamic behavior of a system and the available methods to analyze and improve its stability and accuracy. As for mechanical engineers, they must be able to analyze and design dynamic systems with a variety of physical properties. For example, a simple electro-hydraulic servo valve may contain electrical, magnetic, hydraulic, and mechanical components.

Thus, an increasing percentage of engineers are familiar not only with the fundamentals of control theory, but also with modeling of systems in complex domains.

Automatic control plays an important role in the advancement of engineering and science. It is of critical importance in most engineering disciplines, including aerospace engineering, chemical engineering, robotic systems, automotive engineering, mobile equipment engineering, and manufacturing and industrial processes.

Automatic control provides a means of understanding issues of stability and accuracy in dynamic systems. In fact, most engineers should have a good understanding of this field.

About the Book

Most textbooks on automatic control are intended for electrical engineers. The main problem in designing and analyzing control loops of non-electrical systems usually arises in deducing an appropriate mathematical model of the system. In general, the components cannot be easily represented by simple discrete ideal elements. Classical approaches based on transfer functions and associated analytical techniques are easier for the beginning student to understand and relate to practice than modern control theory.

Therefore, this book was prepared for students of mechanical engineering. It deals with the fundamentals of linear control theory. It includes simple examples to help students understand the problems of accuracy and stability of dynamic systems. Includes examples and exercises that facilitate understanding of control theory, especially for students of mechanical engineering. The book consists of 10 chapters covering the following topics:

  • An introduction showing basic definitions and methods of system representation, Chapter1.
  • Review of mathematical topics, Chapter2.
  • Reasoning about transfer functions using mathematical models, block diagrams, and signal flow graphs, Chapters3, 4, and 5.
  • Analysis of the transient and frequency response of a system, the shape of the transfer function and how the response changes with input excitation. How the transfer function is determined by practical testing of the system is also discussed in Chapters 6 and 7.
  • An analysis of the accuracy and stability of the feedback system, Chapter8.
  • Trajectory analysis, Chapter9.
  • Improving system stability through the introduction and design of various compensators, primarily P, PI, and PID controllers, Chapter10.
