  on the control action of the input signal or
  system set point.
• Examples /application Washing Machine TV
  Remote Control.

• Key Differences between Open Loop and Closed Loop
  System

1. The open loop system means the output of the
   system is free from their input. In the
   closed-loop system, the desired output depends on
   their input.
2. The open loop system is called the non-feedback
   system while the closed loop is the feedback
   system.
3. The open loop system is more stable as compared
   to a closed loop system. Here the word stable
   means the output of the system remains constant
   even after the disturbances.
4. The open loop system is not optimized, whereas
   the closed-loop system is optimized.
5. The calibration of open loop system is difficult
   as compared to the closed-loop system.
