8 Fundamentals of Control Systems
The term control refers to the process of modifying the dynamic behavior of a system in order to achieve some desired outputs.
Control systems exist in many devices and fields. As pointed out in Chapter 1, the theory of control has been employed by economists, medical personnel, financial experts, political scientists, biologists, and engineers, to name but a few.
Within the field of mechanical engineering, the heating system and water heater in a house, or the heating, ventilation, and air conditioning (HVAC) system in a modern building, employ control systems.
In aerospace, the control of aircrafts, helicopters, satellites, and missiles requires very sophisticated advanced control systems.
In shipbuilding industries, control systems are often employed.
