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 âopen-loop systemâ is defined by the fact that the output signal or condition is neither measured nor âfed backâ for comparison with the input signal or system set point.he overall transfer function is: Then the Open-loop Gain is given simply as: When G represents the Transfer Function of the system or subsystem, it can be rewritten as: G(s) = Î¸o(s)/Î¸i(s). Open-loop control systems are often used with processes that require the sequencing of events with the aid of âON-OFFâ signals.
