Advantages:
Accuracy: They are more accurate than open loop system due to their complex construction. They are equally accurate and are not disturbed in the presence of non-linearities.
Noise reduction ability: Since they are composed of a feedback mechanism, so they clear out the errors between input and output signals, and hence remain unaffected to the external noise sources.
Disadvantages:
Construction: They are relatively more complex in construction and hence it adds up to the cost making it costlier than open loop system.
Since it consists of feedback loop, it may create oscillatory response of the system and it also reduces the overall gain of the system.
Stability: It is less stable than open loop system but this disadvantage can be striked off since we can make the sensitivity of the system very small so as to make the system as stable as possible.
