The open loop transfer function of a negative feedback closed loop system is \(\frac{K}{{\left( {{s^2} + 4s} \right)}}\) where K is a non-negative real valued parameter.
1
The closed loop system is stable for only K > 2
2
The closed loop system is an underdamped second order system for K > 4
3
For K > 4, the system has a settling time less than 4s
4
The damping ratio is 0.8 for K = 2.
