Q3: A unity feedback control system is characterized by the open loop transfer function G(s)= k(S+13) (S+3)(s+7)s using the Routh Criterion a) Calculate the range of values of k for the system to be stable, b) What is the marginal value of k for stability ? Determine the frequency of oscillations if any. c) Check if for k=1, all the roots of the characteristic equation of the above system have the damping factor greater than 0.5.
