OPEN LOOP VS CLOSED LOOP

In an open loop control system the control action is

• Dependent on output

• based on feedback from the system

• independent of the output

• Automatically corrected

Which of the following is an example of an closed loop system?

• Electric iron with timer

• Toaster without sensors

• roomheater with thermostat

• Washing machine with fixed timer

The main advantage of an closed loop system is

• Simple design

• Cost effective

• High Accuracy

• Fast operation

In a closed loop system, feedback is used to

• Increase Complexity

• Improve manual control

• Compare output with desired value

• set input manually

Which of the following is true for an open loop system?

• it uses sensors to adjust output

• it corrects errors

• it operates without monitoring output

• it cannot be used in real life
