Routh Criterion(A)-The sufficient and necessary condition is: All the data of the first column of Routh's array must be positive
Routh Criterion (A) – The sufficient and necessary condition is: All the data of the first column of Routh’s array must be positive
Routh criterion: the number of roots on the right half plane is equal to the number of sign changes in the first column of the routh array l+G(s)H(s)=S°+4s3+3s4+2s+s2+4s+4=0 (B) 314 4 04 0 76 15 4 Two roots on the right half plane- system is unstable
(B)
