Which of the following statements is not necessarily correct for open control system ?

A Input command is the sole factor responsible for providing the control action
B Presence of non-linearities causes malfunctioning
C Less expensive
D Generally free from problems of non-linearities

Correct Answer: Presence of non-linearities causes malfunctioning

When the input to a system is independent of the output from the system, then the system is called an open-loop or unmonitored system. It is also called as a calibrated system. Most measuring instruments are open-loop control systems, as for the same input signal, the readings will depend upon things like ambient temperature and pressure.
