Question

Define close loop and open loop system with example

Answer 1

Open-loop System. ... In the past, electrical control systems were basically manual or what is called an Open-loop System with very few automatic control or feedback features built in to regulate the process variable so as to maintain the desired output level or value. For example, an electric clothes dryer.

Answer 2

One type of control system in which the output has no influence or effect on the control action of the input signal is called an Open-loop system. An “open-loop system” is defined by the fact that the output signal or condition is neither measured nor “fed back” for comparison with the input signal or system set point.
