Problem 5. Root Locus: Open loop transfer function for a system is given as L(s) = k 6(s+8/3)(s+100) 100s(s - 2) a) Plot the root locus for L. b) What is minimum value of k for this system to become stable? (Hint: First, approximate L at low frequencies, i.e., w << 100 rad/sec) c) What is maximum value of k for this system to become unstable?
