DBATU Model MCQ – Control System Spread the love Views: 127 [adinserter block="1"] Welcome to your Control System, dated August 4, 2021 1. Find out the Transfer function for the closed loop control system given belowDeselect AnswerG(s)/(1+G(s)*H(s))G(s)/(1- G(s)*H(s))G(s)+H(s)G(s)-H(s) 2. Signal flow graph is used to find _________Deselect AnswerStability of the systemControllability of the systemTransfer function of the systemPoles of the system 3. Gain cross - over frequency is defined asDeselect Answer|G(jω)H(jω)|=1|G(jω)H(jω)|=0|G(jω)H(jω)|=∞|G(jω)H(jω)|=1/2 4. The Transfer function C/R of the block diagram given below isDeselect AnswerG1+(G2/(1+G2H1+H2))G1 G2/(1+G1 H2 H1 H2)G1 G2/( G2H1+ G1 G2 H2+1)G1 G2/(1+G2 H1+ G1 H2) 5. A unity feedback system has Open loop Transfer system (s+1), Then Closed loop Transfer function isDeselect Answers+1s-1s-1/s+3s+1/s+2 6. A system with transfer function G(s) = (s-5)(s-7). Then the zeros are located atDeselect Answers = 1, s=-j+5s = 5, s = 7s = j-5 , s = j-7s = j+5 , s = j+7 7. Find out the Transfer function for the given Pole – Zero plotDeselect Answers-1/s+2s+1/s-2s+1/s2+4s+5s+j/s+2 8. For the first order system having Transfer system 1/(1-sT),the unit impulse response isDeselect Answere –t/TT e –t/T(1/T) * e t/TT2 e –t/T 9. As compared to a Closed loop system an Open loop system isDeselect AnswerMore stable as well as more accurateLess stable as well as less accurateLess stable but more accurateMore stable but less accurate 10.
