In allyl chloride production plant, the experimental process reaction curve data was collected and tabulated in the following table. The data of open loop system was obtained for PI controller. a. Plot time vs measurement of output. b. Obtain the change in input and the ultimate value of output variable. c. Approximate the open-loop response with that of a first-order system plus dead time, K, t and ta. d. Determine the controller settings using Cohen-Coon technique.
