The transfer function in the following case is defined as

On substituting the value of G(s), we have T(s) =

On simplifying we have

Applying R-H criteria,

First of all k > 0 for R - H criteria to be valid

Clearly, 6 − 3k > 0 in order for the system, to be stable. K < />

Thus, sum of maximum and minimum value of k is = 2
