Open Loop System :-An open loop system is one in which the control action is independent of the desired output. The actuating signal depends only on the input command and output has no control over it Closed Loop System:- A closed loop system is one in which control action is some how dependent on the output. In this case the controlled output is feedback through a feedback element and compared with the reference input. Thus the actuating signal is the difference of desired output and reference input. | |
