Need b and c [Q-1, 12 Marks] Answer the following briefly: (Imprecise answers will get zero marks) 1· (a) Check if the dominant poles concept is applicable (show your pole-zero skctch) to the system 630 G(s) (s2 16s 63) (s1.4s 2) and if it is, then i. Obtain the equivalent second order system transfer function i. Calculate the time to peak, overshoot and settling time iii. Sketch the second order system step response with the calculated parameters marked in the sketch (b For the following loop transfer functiorn G3(s +4) i. Find the maximum P gain before the system becomes unstable ii. Find al closed loop poles at this maximum P gain (c) Sketch an ideal op-amp circuit with component values clearly marked to implement the PID controller C(s) 2.50.01s Show ground on the op-amp input terminals as appropriate.
