A unity feedback control system is characterized by the open loop tra...
Where, N = number of encirclements of the critical point.
P = number of open loop poles lying in the RHS of s-plane.
Z = number of closed loop poles lying in the RHS of s-plane.
Here 0
Now finding value of P
Use Routh array to find the number of roots of open loop system lying in the RHS of s-plane.
S3+as2+b
Since a>0, b>0
Therefore, number of sign changes = 2
Hence, P = 2
So, N = P-Z
0 = 2-Z
Z = 2
Hence, two closed loop poles are lying in the RHS of s-plane.
