A control system manages, orders, directs or regulates the behavior of other devices or systems that use control loops. It can range from a single domestic heating controller that uses a thermostat that controls a domestic boiler to large industrial control systems that are used to control processes or machines.
For continuously modulated control, the feedback control system is used to automatically control a process or operation. The control system compares the value or status of the process variable (PV) to be controlled with the desired value or set point (SP), and applies the difference as a control signal to carry the variable process output the plant at the same value as the control signal.
A control system is a system of devices or a set of devices that manages, orders, directs or regulates the behavior of other device (s) or system (s) to achieve the desired results. In other words, the definition of control system can be rewritten as a control system A is a system that controls another system. As human civilization is modernised day by day, the demand for automation increases accordingly. Automation requires a lot of device control.
In recent years, control systems have played a major role in the development and advancement of modern technology and civilization. Virtually every aspect of our daily lives is affected less or more by some control system. A toilet tank, a refrigerator, an air conditioner, a geezer, an iron, an automobile, all are control systems. These systems are also used in industrial processes for more results. We found a control system in product quality control, weapons system, transportation systems, power system, space technology, robotics and many more. The principles of control theory apply to both engineering and engineering.
