The system without feedback is known as open loop system. The examples of the open loop system are bread toaster, oven ,washing machine. The open loop systems are inaccurate & less complex.

The sensitivity of an open loop control system is always 1, it is due to no feedback involved in open loop.

• The open loop system is simple and economical
• easier to construct
• stable

A Closed loop system basically will have a feedback which enables the rectification of the error in the main process,whereas it is not possible in an open loop system
