Question

Assertion (A): Feedback compensation is preferred to series compensation.

Reason (R): No amplification is required as the energy flows from higher to lower levels.

(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

I had been asked this question in a national level competition.

I'm obligated to ask this question of Effect of Adding a Zero to a System in chapter Time Response Analysis, Design Specifications and Performance Indices of Control Systems

Answer 1

Right option is (a) Both assertion and reason are true and R is correct explanation of A

The explanation is: Feedback compensation is preferred to series compensation or cascade compensation because:

In a feedback compensator energy transfer is from higher to a lower one thereby obviating the need for the feedback amplification.
