The block diagram of a feedback compensated system is given below: Which of the following statements are correct? a) When Kt = 0, the feedback compensation is in-effective and the system is uncompensated b) When Kt = 0, the feedback compensation is most effective and system is compensated c) The performance of the compensated system depends on Kt and T d) The performance of the compensated system does not depend on T

The block diagram of a feedback compensated system is given below: Which of the following statements are correct? a) When Kt = 0, the feedback compensation is in-effective and the system is uncompensated b) When Kt = 0, the feedback compensation is most effective and system is compensated c) The performance of the compensated system depends on Kt and T d) The performance of the compensated system does not depend on T Correct Answer (a) and (c)

In a feedback compensated system topology, the resultant compensated system’s parameter depends on the original system and on the compensation network parameter.

 

Comparing this with the standard Compensated network, and from equation (2), it is clear that the roots of the characteristic equation depend on both Kt and T.

So, option (1) is correct.

Consider the following statements with respect to the feedback from the control systems: 1. The feedback can improve stability or be harmful to stability if it is not properly applied. 2. The feedback can always improve stability. 3. In many situations, the feedback can reduce the effect of noise and disturbance on system performance. 4. In general, the sensitivity of the system gain of a feedback system of a parameter variation depends on where the parameter is located. Select the correct statements.
