Positive-Feedback Control Systems

Question

Positive-feedback control systems:
A)have no effect on the deviation from set point.
B)accelerate a change.
C)ignore a change.
D)do not exist in human systems.

Accepted Answer

Positive-feedback control systems are designed to accelerate a change towards the set point rather than maintaining a steady state. They amplify the effect of the deviation from the set point, which can be useful in some scenarios but can also lead to instability if not properly controlled. Hence, option B is the correct choice. The other options are incorrect as they do not accurately describe the function of positive-feedback control systems.
