Advantage and Disadvantage of Closed loop systems.

General

Advantage

  • The closed loop systems are accurate.
  • The closed loop systems are accurate even in the presence of non-linearities.
  • The sensitivity of the systems may be made small to make the system more stable.
  • The closed loop systems are less affected by noise.

Disadvantage

  • The closed loop systems are complex and costlier.
  • The feedback in closed loop system may lead to oscillatory response.
  • The feedback reduces the overall gain of the system.
  • Stability is a major problem in closed loop system and more care is needed to design a stable closed loop system.
