Control Theory and Applications

Control Theory and Applications

Control Theory and Applications contains two parts. In the first part, you will study a few examples of mechanical devices that are controllable using three basic rules of operation: torque, position and angular velocity. You will find examples of systems that use various forms of feedback, and you will learn how to formulate the basic law of conservation of energy. You will also study some well-known problems, like planetary orbit, and consider their underlying physics. In the second part, you will study the theory of free-return navigation, and then build a simple controllable device that can be used to control the behavior of a free-returning spacecraft. The resultant installation will be a case study, in which the control systems are well known and proven.

Principles of Control Theory

• They involve feedback loops with real-world, time-varying dependence on one or more sources of inputs (or demands). A feedback loop is a continuous sequence of one or more steps in which the inputs are varied, and the output is dictated by the current state of the system.
• A first-order system is one where the sum of the amplitudes of all cycles is zero.
• First-order control theory is concerned with the evolution of a system in response to disturbances (often initiated by external stimuli) that cause variations in the system. These disturbances have physical causes that may be external (e.g., sound, light, chemical) or internal (e.g., information).
• A second-order system has further subdivisions.

Applications

The applications are given as "Blaise Pascal Approaches" for students studying electrical engineering and computer science, in an effort to avoid confusion between control theory and computing. Book Review Why Control Systems? Why Small Systems? From fundamental and applied issues such as problem definition, learning, and control theory to methodological problems like understanding the limitations of mathematics, the limits of reason, or the fine line between methodological and theoretical constructs and, finally, applications the book provides the reader with the mental scaffolding he or she needs to understand these topics.

Conclusion

The IEEE Control Systems Society makes it available for the first time to members of the community a paper that presents the most complete presentation of the basics of control theory and applications. It covers issues of fundamental importance to almost all systems. It illustrates the evolution of control theory from linear to nonlinear and more recently considers the synergies between classical and modern control theory. It will be of interest to engineers in virtually any field of engineering, including computer science, telecommunications, aerospace, automotive, and power engineering.
