1.	Which among the following is not an advantage of an open loop system?(a) Simplicity in construction & design(b) Easy maintenance(c) Rare problems of stability(d) Requirements of system re-calibration from time to timeI had been asked this question in an internship interview.The above asked question is from The Design Problem topic in section Design of Control Systems
Answer» Right choice is (d) Requirements of system re-calibration from TIME to time The best I can EXPLAIN: Open loop system is the system with no feedback and the parameter variations in the open loop system are more as compared to the CLOSED loop system and the system has to be re-calibrated as per the requirement as automatic calibration is not PRESENT in this system.
