select all the answers that describe how a control engineer uses negative feedback. Stabilize an unstable system, Reduce the impact of disturbances. C make a system more sensitive to parameter variations improve transient response. simplify performance calculations.

Solution

Reduce the impact of disturbances: Beacuse the cloose loop reduce the error of the system, the eror singnal

e=input(s)-outpu(s) ----->(thanks to the cloose loop)

is given to the controller, the controller will adjust the output taking as reference the error signal, then the impact of disturbances are lower.
