1.	Which of the statements are the advantages of closed loop systems over the open loop system:(a) The overall reliability of the open loop system is more than the closed loop system is more than closed loop system.(b) The transient response in closed loop system decays more quickly than in open loop system.(c) In open loop system closing the loop increases the gain of the system(d) In open loop system the effect of parameter variation is reducedThe question was asked in class test.I'd like to ask this question from Feedback Compensation topic in section Design of Control Systems
Answer» Right option is (b) The transient RESPONSE in closed loop system decays more quickly than in open loop system. The explanation: Speed of response REFERS to the time taken to give the FINAL output and it depends UPON the rise and settling time of the transient response and speed of response of closed loop system is more than that of open loop system.
