Q5.If the closed-loop transfer function of a control system is given as then It is
Answer : Option DExplaination / Solution:
In a minimum phase system, all the poles as well as zeros are on the left half of the s −plane. In given system as there is right half zero (s = 5), the system is a non-minimum phase system.
