A) In open loop system the input is independent of output but output is depends on input.
A-1. no feedback path in open loop s/m
-2. less accuracy than close loop s/m.
Ex. Washing machine, Electric heater, fan etc
B) similarly for close loop system the output is dependent on input and also input is dependent on output value,
B-1 feedback path is provided in C.L system.
-2. high bandwidth.
-3. high accuracy.
Ex. Air conditioner ( AC ), rocket launcher, radar system, etc
