Air conditioner system senses the room temperature and then decides how much cooling has to be provided to room as per the setting. Say u need only 20 degree Celsius only.
To elaborate, in a closed loop system, the output in some way shape or form is fed back into the input of the control system. With an air conditioning system, the output is temperature. This temperature is read, and fed back into the control system to determine if additional cooling is needed or not.
An example of an open loop system would be if you programmed the air conditioning to turn on from 11AM to 5PM, then turn off. The output of the system (temperature) doesn't effect the input (when the system runs).
A closed loop system is one where the output is fed back into the control system. In the case of an air conditioner, the output (cold air) may be fed back to determine if the air conditioner should continue to run (it's still too hot), or if it should turn off.
closed loop system
A Closed loop system basically will have a feedback which enables the rectification of the error in the main process,whereas it is not possible in an open loop system
The closed loop control refers to a system whereby an input forcing function is usually determined in part by the system response.
A cruise control is an example of a closed loop servo.
Sensitivity of a closed loop system for a change in the system gain is 1/(1+GH)

Yes it is
yes
stability and repeatability
Open loop (single cycle) involves a break requiring a restart, easily adapted to closed loop.
The Nyquist stability criterion, named after Harry Nyquist, provides a simple test for stability of a closed-loop control system by examining the open-loop system's Nyquist plot. Under many circumstances, stability of the closed-loop control system may be determined directly by computing the poles of the closed-loop transfer function. In contrast, the Nyquist stability criterion allows stability to be determined without computing the closed-loop poles

open (in terms of thermo chemistry) ! It cannot be proved with science yet! BUT WHEN ONE TOUCHES SOMEONE, LOOKS THEM IN THE EYE, so forth one feels the exchange of energy(emotions). they are being effected by the surrounding !
A control system that appears to be self-regulating. Closed-loop systems employ feedback and a reference of correctness (norm or set point). Deviations from the norm are detected and corrections made in order to maintain a desired state in the system. Closed loop systems provide the homeostatic mechanism of many physiological functions (see negative-feedback) and also control some movement patterns, where feedback from proprioceptors and other receptors play an important part. Compare open-loop-system.
A closed loop control system is a set of mechanical or electronic devices that automatically regulates a process variable to a desired state or set point without human interaction. Closed loop control systems contrast with open loop control systems, which require manual input.
