QUESTION: 3

### The transfer function represent a

Solution:
QUESTION: 4

A lag compensation network
(a) increases the gain of the original network without affecting stability.
(b) reduces the steady state error.
(c) reduces the speed of response
(d) permits the increase of gain of phase margin is acceptable.
In the above statements, which are correct

Solution:
QUESTION: 5

Phase lag controller:

Solution:

Phase lag controller is the integral controller that creates the phase lag and does not affect the value of the damping factor and that tries to reduce the steady state error.
