Closed Loop Control System

This is a control term.

In any control system you have an 'input', 'process' and 'output'

But there is fourth item that may - or may not - be present. This item is called 'feedback'.

Feedback is a method of letting the input know what the output is doing. This means feedback can affect the way the control system works.

A control system is said to be 'closed loop' if it includes feedback

A control system is said to be 'open loop' of it does not contain feedback.

A Closed Loop Control system is where the output of the system can affect the next decision.

For example a closed loop central heating system coming up to its proper temperature will start to affect the way the boiler is turning off and on based on the current room temperature.
