PI controllers:

a) can eliminate constant disturbances from the output but they cannot increase the Bandwidth of the loop.

b)can eliminate constant disturbances from the output and always increase the Bandwidth of the loop.

c)cannot eliminate constant input disturbances from the output but they increase the Bandwidth of the loop.

c)can eliminate constant disturbances from the output and always decrease the Bandwidth of the loop.

d)None of the above.

Solution

PI controllers can eliminate constant disturbances from the output and always increase the bandwidth of the loop.

Therefore the correct option is (B).
