Chemical Engineering Department University of Florida ECH 4323L FINAL PROJECT COMPUTER SIMULATION STUDIES OF PID CONTROL LOOP DYNAMICS USING SIMULINK Student Name:_______________________________ 1.0 Create a SIMULINK program as illustrated in the figure below, that carries out a computer simulation of a closed-loop system consisting of a first-order plus dead time process y ( s ) = Κ τσ + 1 ε - θσ υ ( σ 29 + δ ( 29 where d ( s ) is a disturbance signal, and a standard PID controller with transfer function u ( s ) = χ 1+ 1 τ Ι + ( 29 where e ( s ) = ρ ( 29 - ψ ( 29 is the feedback error. 1.1 Consider the case where the process parameters are K = 2 , = 1, and θ = 5 . 1.1.1 Tune the controller for P-only servo-performance using the following tuning techniques: (a) the Ziegler-Nichols process reaction curve method, and (b) the © Oscar D.

ECH 4323L Final Project 2 Cohen-and-Coon method. Report the values of the controller parameters for (a)-(b) in a table . Carry out a servo test (unit-step set-point change, zero disturbance) for each one of the cases (a) and (b). Create a graph consisting of two plots in one page. The top plot should show the set point and each of the two servo responses as a function of time, and the bottom plot should display each of the input-signals as a function of time. Write a brief paragraph describing which controller tuning is more aggressive, and whether offset is fully eliminated. Notes : - Use different line types for each of curve in a given plot. Include a legend when the plot has one more than curve. - The title of the top plot should read “FINAL PROJECT, Problem 1.1.1”, followed by your name. Hint 1 : Use the MATLAB commands subplot(121), subplot(122), grid, xlabel, ylabel, axis, and legend . Hint 2 : When using the SIMULINK sink entitled “ To Workspace ”, make sure to double-click on the sink and select the Save Format as Array . Then click on the Apply button. 1.1.2
