The given characteristic equation s4+s3+2s2+2s+3=0 has:
A. Zero root in the s-plane
B. One root in the RHS of s-plane
C. Two root in the RHS of s-plane
D. Three root in the RHS of s-plane
Answer:C
The given characteristic equation s4+s3+2s2+2s+3=0 has:
A. Zero root in the s-plane B. One root in the RHS of s-plane C. Two root in the RHS of s-plane D. Three root in the RHS of s-plane
Explanation: The stability analysis is done using Routh-Hurwitz criterion and hence the number of roots on the right is calculated.
