Reason (R): A PI controller introduces a pole at either the origin or at a desired points on the negative real axis.
A. Both assertion and reason are true and R is correct explanation of A
B. Both A and R true but R is not correct explanation of A
C. A is true but R is false
D. A is False but R is true
Answer:A
Reason (R): A PI controller introduces a pole at either the origin or at a desired points on the negative real axis.
A. Both assertion and reason are true and R is correct explanation of A B. Both A and R true but R is not correct explanation of A C. A is true but R is false D. A is False but R is true
Explanation: I is proportional +integral controller. Thus integral controller add a pole either at origin or at the desired point on the negative real axis, so order of the system gets increased but it reduces the steady state error of the offset error.
