1.	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-linearitiesThis question was posed to me in final exam.This is a very interesting question from Observer Systems topic in portion State Variable Analysis and Design of Control Systems
Answer» The correct option is (b) PRESENCE of non-linearities causes malfunctioning To elaborate: OPEN LOOP control system are the systems which have no feedback and cannot be used to obtain the DESIRED response and non-linearities does not cause malfunctioning.
