Main Objectives of Control System
1. To define a control system.
2. To explain why control systems are important.
3. To introduce the basic components of a control system.
4. To give some examples of control-system applications.
5. To explain why feedback is incorporated into most control systems.
6. To introduce types of control systems.
Over the past five decades, control systems have assumed an increasingly important role in the development and advancement of modern civilization and technology. Practically every aspect of our day-to-day activities is affected by some type of control system. For instance, in the domestic domain, we need to regulate the temperature and humidity of homes and buildings for comfortable living.
For transportation, various functionalities of the modern automobiles and airplanes involve control systems. Industrially, manufacturing processes contain numerous objectives for products that will satisfy the precision and cost-effectiveness requirements.
A human being is capable of performing a wide range of tasks, including decision making. Some of these tasks, such as picking up objects and walking from one point to another, are commonly carried out in a routine fashion. Under certain conditions, some of these tasks are to be performed in the best possible way.
For instance, an athlete running a 100-yd dash has the objective of running that distance in the shortest possible time. A marathon runner, on the other hand, not only must run the distance as quickly as possible, but, in doing so, he or she must also control the consumption of energy and devise the best strategy for the race. The means of achieving these “objectives” usually involve the use of control systems that implement certain control strategies.
Control systems are found in abundance in all sectors of industry, such as:
"Quality control of manufactured products, Automatic assembly lines.
Machine tool control, Space technology, Computer control, Transportation systems, Power systems.
Robotics, Micro-electro-mechanical systems (MEMS), Nano-technology, and many others."
Even the control of inventory and social and economic systems may be approached from the control system theory. More specifically, applications of control systems benefit many areas, including.
Control systems abound in modern civilization.
• Process control: Enable automation and mass production in industrial setting.
• Machine tools: Improve precision and increase productivity.
• Robotic systems: Enable motion and speed control.
• Transportation systems: Various functionalities of the modern automobiles and airplanes involve control systems.
• MEMS: Enable the manufacturing of very small electromechanical devices such as microsensors and micro actuators.
• Lab-on-a-chip: Enable functionality of several laboratory tasks on a single chip of only millimeters to a few square centimeters in size for medical diagnostics or environmental monitoring.
• Biomechanical and biomedical. Artificial muscles, drug delivery systems, and other assistive technologies.
