What's the difference between open loop control and closed loop control?

Dear Albay Callon,

I will give you an example to understand about open loop control system and closed loop control systems.

Suppose we are flying a kite. If we want the kite to go higher then we have to loose the thread first and then immediately pulling the thread so that it can go higher. Here, loosing of thread and pulling of thread is the input to the system and the decision of pulling and loosing is coming through feedback and with this the kite is controlled to fly in the sky.   Now here, Input = through thread, System = kite, feedback = eye and output = happily flying kite, so this type of controlled system is known as closed loop control system.

Now come to open loop: Suppose we are considering the same system of flying kite. This time we are going to face the kite from the back side and there is no connection of eye with the kite, means that either loos the thread or pull the thread, it is not in your hand to make a stable fly or one can say controlled fly of the kite. Now here, Input = through thread, System = kite, feedback = no feedback and output = unhappy flying kite, so this type of controlled system is known as open loop control system.

Hope this explanation will help you to understand about open and closed loop control system.

An open-loop control system takes input under the consideration and doesn’t react on the feedback to obtain the output. But a closed loop system is also referred as a feedback control system

We can save our meterials when we closed loop

the cloosed loop has a feedback 

open loop control means there is The beginning of loop & end of it, but closed loop meand frist device in loop its last device also
