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
Negative feedback is a feedback where it is used in negative side in a closed loop system.Such as a inverting side feedback in op-amp.
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 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.
Yes it is
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.
