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.

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
Sensitivity of a closed loop system for a change in the system gain is 1/(1+GH)
A closed loop system for the purpose of feeding back the output signal to the input side requires sophisticated sensors, which make this scheme expensive to implement. Initial tuning of the system is also difficult(feedback serves the purpose of fine tuning).

Yes it is
In industry closed control is a closed loop feedback where a pump or motor has an encoder or feedback device to keep the operation regulated.
yes
stability and repeatability
It refers to asystem whereby the loop of control is closed to outside interference.
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
The four different control modes are open-loop control, closed-loop control, feedforward control, and feedback control. Open-loop control operates without measuring the output, while closed-loop control adjusts actions based on output feedback. Feedforward control anticipates changes and adjusts inputs proactively, and feedback control continuously monitors outputs to correct any deviations from the desired performance. Each mode serves different applications depending on system requirements and desired accuracy.
