Consider the PCM distillation column module of ApC\ pendix
Chapter 15, Problem 15.14(choose chapter or problem)
Consider the PCM distillation column module of ApC\ pendix E. Assume that distillate methanol composition ~ xv is the CV, reflux ratio R is the MV, and feed composition xp is the DV. (a) Using the transfer functions given below, design a feedforward control system. (b) Design a PID controller based on IMC tuning and a reasonable value of Tc (c) Simulate the FF, FB, and combined FF-FB controllers for a sudden change in d at t = 10 min, from 0.50 to 0.55 (mole fraction). Which controller is superior? Justify your answer. Xv R G = 0.126e-l3Ss P 762s +
