Stability Theory » Exercise - 133. If the system has non repeated poles on the jω axis, the system is : (a) stable (b) unstable (c) marginally stable (d) conditionally stable
Stability Theory » Exercise - 132. If all the roots of the characteristic equation have negative real parts, then the system is : (a) stable (b) unstable (c) conditionally stable (d) marginally stable
Stability Theory » Exercise - 130. The characteristic equation 1 + G(s)H(s) = 0 of a system is given by s4 + 8s3 +12s2 +8s + K = 0 For the system to remain stable, the value of gain K should be : (a) zero (b) 0< K (c) >11 (d) positives
