Open loop systems

The system which doesn’t have any feedback loops connected to it is called "Open loop feedback system", as there is no feedback loop, no data is transferred back to the open loop systems.
It is a type of continuous control system. These systems do not take into account the output signa in the control action.


Here we have some examples of an open loop control systems:
-Washing machines
-light switches
-gas ovens 
-fans
For example, when we turn on a fan, it operates regardless of the room temperature.

We use open loop control systems in many applications of our day to day life, for example, a TV remote control and an electric hand drier
