The open-loop transfer function of a unity feedback system is K/(s^^2 (s+5))The system is unstable for(a) K>5(b) K0(d) All of the mentionedThe question was posed to me during an interview.This question is from Construction of Phase-Trajectories in section Nonlinear Systems of Control Systems

Answer»

Correct option is (d) All of the mentioned

The explanation: The open loop transfer FUNCTION of a unity feedback SYSTEM is used to CALCULATE the conditional stability by using the Routh Hurwitz CRITERIA or the Root locus technique.
