Detailed Solution for Test: Introduction to Control Systems- 2 - Question 10

The advantages of a closed-loop system (with feedback)

i) Improved sensitivity performance (the system is lesser sensitive to parameter variations)

ii) The bandwidth of the system increases.

iii) Effect of internal disturbances reduces.

speed ∝ bandwidth

The disadvantages are

i) Reduced gain – gain reduces by a factor 1 + GH

ii) The system can be unstable.
