Sensitivity of a closed loop system for a change in the system gain is 1/(1+GH)
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.
no
An open loop traffic signal just cycles on a schedule and has no "knowledge" of traffic patterns or current traffic. A closed loop system would have sensors letting it know when traffic was present and a controller that would make decisions based on the traffic conditions.
The sensitivity of an open loop control system is always 1, it is due to no feedback involved in open loop.

Brown bear have a close circulation system
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 !
Open loop (single cycle) involves a break requiring a restart, easily adapted to closed loop.
In a closed loop system the gain without the feed back loop being closed is called open loop gain!!! e.g if forward gain is "A" and feed back factor is "B" then open loop gain is "AB" and closed loop gain will be [A/(A+B)]
its costly than open loop system and bulky, too.
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.
