1- Devise a cascade control structure for this exothermic reactor and show the control loops on the schematic diagram 2. Construct the control loops on a block diagram 3. Jerive and develop the closed loop transfer functions relating the primary control objective to the setpoint and to the Feed-in disturbance flow Hint: use Gp(i), Gd(i), Go(i), Gm(i) and Gv(i) to denote the transfer functions of the different processes, disturbances d, controllers, measurement devices and final control elements (i=1,2)
