● The initial slope is – 20dB/d it means system is type 1.
● At ω1 there is – 20dB/d more means there is a pole i.e., 1/(1 + sT1)
where T1 = 1 ω1
● At ω2 there is increase in 20dB/d means a zero i.e., (1 + sT2),
where T2 = 1/ω2
● At ω3 there is – 20dB/d more means there is a pole i.e., 1/(1 + sT3)
where, T3 = 1/ω3
Now, the general form of the open-loop transfer function isG(s)H(s) = K(sT2 + 1) s(sT1 + 1)(sT3 + 1)
Correct Option: A
