  • What is the difference between open loop and closed loop

    In open loop system there is no any feedback circuit and the system is not automatic. Control can be made manually. e.g- A.C with temperature sensor and control circuit is a feedback system. When any one ride a bicycle the speed is controlled manually by rider is an example of open loop system.
