Basis For Comparison Open Loop System Closed Loop System
Definition The system whose control action is free from the output is known as the open loop control system. In closed loop, the output depends on the control action of the system.
Other Name Non-feedback System Feedback System
Components Controller and Controlled Process. Amplifier, Controller, Controlled Process, Feedback.
Construction Simple Complex
Reliability Non-reliable Reliable
Accuracy Depends on calibration Accurate because of feedback.
Stability Stable Less Stable
Optimization Not-Possible Possible
Response Fast Slow
Calibration Difficult Easy
System Disturbance Affected Not-affected
Linearity Non-linear Linear
Examples Traffic light, automatic washing machine, immersion rod, TV remote etc. Air conditioner, temperature control system, speed and pressure control system, refrigerator, toaster.
