Problem 9: For a system, you would like the system behavior to have 16% OS and reach steady state in 2 second with 2% error bound. Where are the dominant poles? ANS: (a) -3.2 +4.62 (b) -1.6 +j3.46 (C) -2 +j3.46 (d) -2.5 +j1.46 Problem 10: If the desired closed-loop system has poles at -4 and -3 tj 2.5, then for a full order where you possibly select the ploes for the observer? ANS: (a) 2 and 3 tj 2.5 (b) -2 and 3 tj 2.5 (C) -5 and -3 +3 5.5 (d) 20 and -15 +j 3.5
