Example Of Automatic Control System

Traffic lights control system having sensor at the input is an example of a closed loop control system. Automation is the technology by which a process or procedure is performed with minimal human assistance. A control system manages commands directs or regulates the behavior of other devices or systems using control loops it can range from a single home heating controller using a thermostat controlling a domestic boiler to large industrial control systems which are used for controlling processes or machines.

Such system takes feedback from outut and performs the required action accordingly.

Example of automatic control system. The entire construction requires a sensor for taking input some sort of controller which performs the action and a feedback taken from the output. As the user is not a part of the system this system is called open loop system. Given below are 10 examples of closed loop control systems. An automatic toaster with feedback is taken as an example of the practical closed loop control system.

Measurement comparison computation correction in the water tank level control system in the example above the level transmitter measures the level within the tank. The system input is also ineffective to disturbance produced in the toaster due to loss of addition of heat from surroundings. In this combination the output of the control system is adjusted automatically till we get the desired response. For continuously modulated control a feedback controller is used to automatically.

Functions of automatic control in any automatic control system the four basic functions that occur are. Automation or automatic control is the use of various control systems for operating equipment such as machinery processes in factories boilers and heat treating ovens switching on telephone networks steering and stabilization of ships aircraft and other applications and vehicles with. B practical closed loop system. The automatic control system of the iot automatic additional manure supplement device photograph 6 3 5 automatically controls the ec value the density of the manure in the culture solution and the ph value the culture solution in its tank is provided to the cultivation tray inside the cells through the supply nozzles at each stage by the pump.

Hence the closed loop control systems are also called the automatic control systems.
