Hello
I have question about an exercise, I don't know how can I solve it :
The open loop transfer function of a unity feedback control system is given by
G(s)*H(s)=K/(s(s+1)(2s+1)(3s+1))
First question :
What is the value of K which will cause sustained oscillations in the closed loop system ?
Second question :
What is the frequency of sustained oscillations ?
Do you know how can I do ? what is the method to answer them ?
regards
