Problem 12.3

A process has the transfer function, G(s) = 2e-0 2s! (s + 1). Compare the PI controller settings for the following design approaches: (a) Direct Synthesis method (Tc = 0.2) (b) Direct Synthesis method (Tc = 1.0) (c) ITAE performance index (disturbance) (d) ITAE performance index (set point) (e) Which controller has the most conservative settings? Which has the least conservative? (t) For the two controllers of part (e), simulate the closedloop responses to a unit step disturbance, assuming that Gd(s) = G(s).
