b) The open loop transfer function of a unity feedback system is: G(s)=2s5+16s4+8s3+32s2+6s16 Apply Routh-Hurwitz criteria to check the stability of the system. i. Is this system stable, unstable, or marginal stable? ii. What is the distribution of the roots of the characteristic equation? (i.e., how many roots are in the LHP, RHP and on the imaginary axis). iii. Find the values of roots on the imaginary axis
