Question 1

A second order process having transfer function G(s) = is cascaded with a standard PD controller in unity feedback configuration. If the closed loop system have velocity error constant KV = 300 and damping ratio ζ = 0.6, then the value of controller gain (kP) is

Question 2

The transfer function of a lag compensator is given as, G(s)=k
If this lag compensator is designed by the RC circuit shown below, then the value of α will be

Question 3

The lead compensator has pole at s= -4 and a zero at s= -2. Then the maximum phase lead m and the corresponding frequency m is

Question 4

The transfer function of a PID controller is given by G(s) = 10[1++2s] as ω tends to zero

Question 5

A lead compensator network includes a parallel combination of R and C in the feed-forward path. If the transfer function of the compensator is Description: D:\GradeStack Courses\GATE Tests (Sent by Ravi)\GATE EC 10-Mar\GATE-ECE-2015-Paper-1_files\image253.png, the value of RC is _________.
